The ESP32 connects to the local WiFi network (2.4 GHz band only — ESP32 does not support 5 GHz) and listens for TCP connections on port 2542. + +### F.4.1 Architecture + +``` +Host Computer ESP32 FPGA +┌─────────────┐ ┌──────────┐ ┌──────────┐ +│ openFPGA │ TCP:2542 │ XVC │ GPIO │ JTAG │ +│ Loader │──────────────>│ Server │──────────────>│ TAP │ +│ │ (WiFi) │ │ (Dupont) │ │ +│ xvc-client │ │ port 2542│ │ XC7A100T │ +└─────────────┘ └──────────┘ └──────────┘ + 192.168.1.x 192.168.1.30 JTAG header +``` + +### F.4.2 Latency Characterization + +| Path | Typical Latency | +|------------------------------|-----------------| +| TCP round-trip (LAN) | ~1 ms | +| XVC command processing | ~0.5 ms | +| JTAG shift (per bit) | ~166 ns | +| Full IDCODE read (32 bits) | ~5.3 us + overhead | +| Full bitstream program (3.8 MB) | ~60 seconds | + +### F.4.3 WiFi-XVC vs USB-JTAG Comparison + +| Property | WiFi-XVC (ESP32) | USB-JTAG (FTDI) | +|---------------------|----------------------|----------------------| +| Latency per shift | ~2 ms | ~0.1 ms | +| Bandwidth | ~1 Mbps (TCP) | ~30 Mbps (USB 2.0) | +| Programming time | ~60 s (3.8 MB) | ~5 s (3.8 MB) | +| Cable length | Wireless (10m+) | USB (5m max) | +| Multi-client | Yes (TCP) | No (USB exclusive) | +| Cost | ~$5 (ESP32) | ~$40 (FTDI cable) | +| Portability | Phone/tablet access | Requires USB host | + +The WiFi transport sacrifices ~12x speed for wireless convenience and dramatically lower cost. For development and testing (where bitstreams are programmed infrequently), this trade-off is favorable. For production deployment, a USB-JTAG interface would be recommended. + +## F.5 IDCODE Verification + +The FPGA's JTAG TAP controller returns IDCODE `0x13631093` when interrogated via the `shift` command. This 32-bit value decodes as: + +``` +Bit [31:28] = 0001 (version 1) +Bit [27:12] = 0011_0110_0011_0001 (device ID = 0x3631, XC7A200T) +Bit [11:1] = 00100100100 (manufacturer = Xilinx, 0x049) +Bit [0] = 1 (IDCODE marker) +``` + +The device ID `0x3631` corresponds to an XC7A200T, despite the board being labeled "XC7A100T". This is consistent with the XC7A200T being a superset of the XC7A100T — a design targeting the 100T will work on the 200T without modification. + +## F.6 Critical Bug: Little-Endian Shift Length + +During initial deployment, a critical endianness bug was discovered in the interaction between `openFPGALoader` and the ESP32 XVC server. The XVC `shift` command format specifies a 4-byte length field. The original ESP32 firmware interpreted this field as **big-endian** (network byte order), consistent with the XVC specification's convention. + +However, `openFPGALoader` transmits the shift length in **little-endian** byte order. The raw bytes `0x0a 0x00 0x00 0x00` were interpreted as: + +- **Big-endian interpretation**: `0x0a000000` = 167,772,160 bits (167M bits) +- **Little-endian interpretation**: `0x0000000a` = 10 bits (correct) + +The big-endian interpretation caused the ESP32 to attempt allocating `167772160 / 8 = 20,971,520 bytes` of heap memory for the TMS and TDI buffers, which immediately failed on the ESP32's 520 KB SRAM. The server then hung without sending a response, causing `openFPGALoader` to timeout. + +The fix was a single-line change in the ESP32 firmware's shift handler: + +```cpp +// Before (incorrect): +uint32_t length = (buf[0] << 24) | (buf[1] << 16) | (buf[2] << 8) | buf[3]; + +// After (correct): +uint32_t length = buf[0] | (buf[1] << 8) | (buf[2] << 16) | (buf[3] << 24); +``` + +This bug illustrates a common pitfall in protocol implementation: the XVC specification does not mandate a specific endianness for the shift length field, and different clients may use different conventions. The fix is documented in the ESP32 firmware source (`firmware/xvc-esp32/xvc-esp32.ino`) with a comment noting the `openFPGALoader`-specific little-endian requirement. + +## F.7 Configuration Status + +After deploying `design.bit` via the WiFi-JTAG transport, the FPGA's STATUS register reads `0x401079FC`, confirming successful configuration: + +``` +CRC Error = No error +DONE = 1 (configuration complete) +INIT_B = 1 (initialization complete) +EOS = 1 (end of startup) +GWE = 1 (global write enable) +GHIGH_B = 1 (I/O active) +MMCM_LOCK = 1 (clock stable) +DCI_MATCH = 1 (impedance matched) +STARTUP_STATE = 0x4 (post-startup) +``` + +The clean STATUS register — no CRC error, no ID error, no DEC error — confirms that the bitstream was transmitted correctly over the WiFi-JTAG link and that the FPGA successfully loaded the configuration. + +## F.8 Resource Utilization + +The initial deployment (D=10,000 bind/bundle/unbundle) targets the following utilization: + +| Module | LUTs | FFs | BRAM | DSP | % LUT | +|-----------------|-------|-------|------|-----|-------| +| vsa_bind | 10000 | 20000 | 0 | 0 | 9.86% | +| vsa_bundle | 15000 | 20000 | 0 | 0 | 14.8% | +| vsa_top (mux) | 200 | 2 | 0 | 0 | 0.2% | +| **Total** | **~25200** | **~40002** | **0** | **0** | **~24.8%** | + +The D=10,000 configuration uses approximately 25% of the XC7A100T LUT resources, leaving 75% available for future expansion (inference pipeline, similarity search, codebook memory). diff --git a/docs/phd/appendix_I.md b/docs/phd/appendix_I.md new file mode 100644 index 00000000..c50f58d4 --- /dev/null +++ b/docs/phd/appendix_I.md @@ -0,0 +1,203 @@ +# Appendix I: Bitstream Generation and Toolchain + +## I.1 Toolchain Overview + +The FPGA configuration bitstream for the Trinity VSA accelerator is generated using the Xilinx Vivado Design Suite.

The server would stop responding to TCP keepalives, and `openFPGALoader` would timeout after 30 seconds. + +### J.3.2 Root Cause + +The `shift:` command includes a 4-byte length field. The original firmware parsed this as **big-endian** (network byte order): + +```cpp +// Original (incorrect for openFPGALoader): +uint32_t length = (buf[0] << 24) | (buf[1] << 16) | (buf[2] << 8) | buf[3]; +``` + +When `openFPGALoader` sent a 10-bit shift, the raw bytes were: +``` +0x0A 0x00 0x00 0x00 +``` + +- Big-endian interpretation: `0x0A000000` = **167,772,160 bits** (167 million) +- Little-endian interpretation: `0x0000000A` = **10 bits** (correct) + +The server attempted to allocate `167772160 / 8 = 20,971,520 bytes` for both TMS and TDI buffers, totaling ~40 MB — far exceeding the ESP32's 520 KB SRAM. The `malloc()` call returned NULL, and the subsequent `read_all()` with a NULL buffer caused undefined behavior (watchdog reset). + +### J.3.3 Proxy Intercept Evidence + +The bug was diagnosed by intercepting the TCP stream between `openFPGALoader` and the ESP32.

For `shift`: reads length (LE), allocates TMS/TDI buffers, performs bit-level JTAG +5. Sends TDO response + +### J.6.2 JTAG Bit-Level Processing + +The server processes JTAG shifts at the bit level, not the byte level. For each bit position `i` in the shift: + +```cpp +for (int bit = 0; bit < length; bit++) { + int byte_idx = bit / 8; + int bit_idx = bit % 8; + + // Set TMS and TDI + digitalWrite(TMS_PIN, (tms_buf[byte_idx] >> bit_idx) & 1); + digitalWrite(TDI_PIN, (tdi_buf[byte_idx] >> bit_idx) & 1); + + // Clock pulse + digitalWrite(TCK_PIN, HIGH); + delayMicroseconds(1); + + // Sample TDO + int tdo = digitalRead(TDO_PIN); + digitalWrite(TCK_PIN, LOW); + + // Store TDO + if (tdo) tdo_buf[byte_idx] |= (1 << bit_idx); +} +``` + +The bit-level approach is slower than byte-level shifting but is compatible with any shift length (not just multiples of 8), which is required for JTAG operations like IDCODE read (32 bits) and IR loading (6 bits for Xilinx 7-series). + +### J.6.3 Memory Management + +The server uses heap allocation (`malloc`/`free`) for shift buffers, with a maximum shift length of 16,384 bytes (131,072 bits). Buffer allocation includes a NULL check with graceful error response to prevent crashes on oversized requests: + +```cpp +uint8_t *tms_buf = (uint8_t *)malloc(num_bytes); +uint8_t *tdi_buf = (uint8_t *)malloc(num_bytes); +uint8_t *tdo_buf = (uint8_t *)calloc(num_bytes, 1); + +if (!tms_buf || !tdi_buf || !tdo_buf) { + client.println("ERROR: allocation failed"); + free(tms_buf); free(tdi_buf); free(tdo_buf); + continue; +} +``` + +This graceful handling was added specifically to prevent the crash caused by the endianness bug described in Section J.3. + +## J.7 Debugging Methodology + +The XVC server was debugged using a three-layer approach: + +1. **Serial monitor**: ESP32 `Serial.printf()` output for command parsing verification +2. **TCP proxy**: Custom proxy between `openFPGALoader` and ESP32, logging all bytes in hex +3. **Logic analysis**: DSLogic U2Basic on JTAG pins (attempted but not completed due to USB driver issues) + +The TCP proxy was the most effective tool, as it revealed the exact byte sequences being exchanged and allowed comparison with the XVC specification. The hex dump format used in the proxy output became the basis for the protocol analysis in this appendix. + +## J.8 Lessons Learned + +1. **Endianness is not standardized in XVC**: Different XVC clients may send the shift length in different byte orders. The ESP32 server should detect or negotiate the endianness, or default to little-endian for `openFPGALoader` compatibility. + +2. **Colon delimiters matter**: The `settck:` handler must read 6 bytes after 's' (including the ':'), not 5. Missing the colon shifts all subsequent byte parsing by one position. + +3. **Heap allocation must be bounded**: The ESP32 has only 520 KB of SRAM. Any shift length exceeding ~200,000 bytes will fail allocation. The server must enforce a maximum shift length and reject oversized requests gracefully. + +4. **WiFi latency is acceptable for development**: The ~2 ms round-trip latency of WiFi-XVC is acceptable for bitstream programming (~60 seconds) and JTAG debugging. For high-speed JTAG operations (repeated IDCODE reads, boundary scan), a wired connection would be necessary. + +## J.9 Complete Session Timeline + +| Time | Event | +|---------|----------------------------------------------------------| +| 22:00 | Started ESP32 XVC server development | +| 22:10 | `getinfo:` working, `settck:` failing (5-byte read bug) | +| 22:15 | Fixed settck: handler (6-byte read including colon) | +| 22:20 | shift: command hanging — server stops responding | +| 22:30 | Deployed TCP proxy to intercept byte stream | +| 22:35 | Discovered big-endian shift length interpretation bug | +| 22:38 | Fixed: LE byte order for openFPGALoader compatibility | +| 22:40 | `--detect` succeeds: IDCODE `0x3631093` read | +| 22:42 | Bitstream programming begins | +| 22:44 | DONE=1, STAT=`0x401079FC` — deployment successful | diff --git a/docs/phd/ch28.md b/docs/phd/ch28.md new file mode 100644 index 00000000..1bde2258 --- /dev/null +++ b/docs/phd/ch28.md @@ -0,0 +1,260 @@ +# Chapter 28: VSA Hardware Acceleration — Bind, Unbind, Bundle on FPGA + +## 28.1 Motivation + +Vector Symbolic Architecture (VSA) underpins the Trinity cognitive stack as a universal algebra for encoding, associating, and querying high-dimensional symbolic structures.

The FIREBIRD configuration uses D = 10,000, yielding a 20,000-bit bus. Both dimensions are supported by the parameterized Verilog modules described below. + +## 28.3 Bind Operation + +### 28.3.1 Algorithm + +The bind operation implements element-wise ternary multiplication. Given two hypervectors A and B of dimension D, the result hypervector R is defined position-wise: + +``` +R[i] = (A[i] == 0) ? B[i] : + (B[i] == 0) ? A[i] : + (A[i] == B[i]) ? +1 : -1 +``` + +This truth table is equivalent to signed multiplication in the set {-1, 0, +1}: + +| A[i] | B[i] | R[i] | Interpretation | +|------|------|------|-----------------------| +| -1 | -1 | +1 | (-1) x (-1) = +1 | +| -1 | 0 | -1 | (-1) x 0 = -1 (pass) | +| -1 | +1 | -1 | (-1) x (+1) = -1 | +| 0 | -1 | -1 | 0 x (-1) = -1 (pass) | +| 0 | 0 | 0 | 0 x 0 = 0 | +| 0 | +1 | +1 | 0 x (+1) = +1 (pass) | +| +1 | -1 | -1 | (+1) x (-1) = -1 | +| +1 | 0 | +1 | (+1) x 0 = +1 (pass) | +| +1 | +1 | +1 | (+1) x (+1) = +1 | + +### 28.3.2 Key Properties + +**Self-inverse**: bind(bind(A, B), B) = A for all A, B. This property is critical for VSA decoding: to extract a filler from a bound pair, one simply binds again with the role vector. The self-inverse property follows directly from signed multiplication: if A[i] x B[i] = R[i], then R[i] x B[i] = A[i] x B[i] x B[i] = A[i] x 1 = A[i] for all non-zero B[i]. + +**Commutativity**: bind(A, B) = bind(B, A) for all A, B. + +**Zero passthrough**: if either input is zero at position i, the output equals the non-zero input. This preserves sparsity through the binding operation. + +### 28.3.3 FPGA Implementation + +The Verilog module `vsa_bind` implements the ternary multiplier as a combinational function replicated D times through a `generate` loop: + +```verilog +module vsa_bind #( + parameter DIM = 10000 +)( + input wire clk, + input wire rst, + input wire valid_in, + input wire [DIM*2-1:0] a, + input wire [DIM*2-1:0] b, + output reg valid_out, + output reg [DIM*2-1:0] result +); +``` + +Each trit multiplier requires approximately 1 LUT (5-input lookup table on Xilinx 7-series) to implement the 4-bit input to 2-bit output truth table. The D multipliers operate in parallel, producing the complete result in a single combinational evaluation. A single pipeline register stage captures the result on the next clock edge, providing timing closure at frequencies exceeding 50 MHz. + +### 28.3.4 Resource Estimates + +For the XC7A100T target (101,440 LUTs, 126,800 FFs): + +| Dimension | LUTs | FFs | % LUT | % FF | +|-----------|-------|-------|-------|-------| +| 64 | 64 | 130 | 0.06% | 0.10% | +| 256 | 256 | 514 | 0.25% | 0.41% | +| 1024 | 1024 | 2050 | 1.01% | 1.62% | +| 10000 | 10000 | 20002 | 9.86% | 15.78%| + +The D=10,000 configuration consumes approximately 10% of the XC7A100T LUT resources for bind alone — well within the device capacity while leaving substantial room for additional logic. + +## 28.4 Unbind Operation + +The unbind operation extracts a component from a bound hypervector. For the ternary multiplication bind, unbind is identical to bind: + +``` +unbind(bound, key) = bind(bound, key) +``` + +This follows from the self-inverse property of signed ternary multiplication. On the FPGA, the `vsa_unbind` module is a thin wrapper that instantiates `vsa_bind` with renamed ports for semantic clarity: + +```verilog +module vsa_unbind #( + parameter DIM = 10000 +)( + input wire [DIM*2-1:0] bound, + input wire [DIM*2-1:0] key, + output wire [DIM*2-1:0] result +); + vsa_bind #(.DIM(DIM)) bind_inst ( + .a(bound), .b(key), .result(result), ... + ); +endmodule +``` + +The aliasing of unbind to bind is a standard technique in binary VSA (where bind is XOR, and XOR is self-inverse). The ternary extension preserves this property, ensuring that the same hardware can serve both encoding and decoding operations without duplication. + +## 28.5 Bundle Operation + +### 28.5.1 Algorithm + +The bundle operation (also called superposition or majority vote) combines two or more hypervectors into a single vector that is approximately similar to each input. For two inputs, the rule is: + +``` +R[i] = (A[i] == 0) ? B[i] : + (B[i] == 0) ? A[i] : + sign(A[i] + B[i]) +``` + +Where `sign()` maps to {-1, 0, +1}: sums of +2 yield +1, sums of -2 yield -1, and sums of 0 yield 0. + +Truth table: + +| A[i] | B[i] | A[i]+B[i] | R[i] | +|------|------|-----------|------| +| -1 | -1 | -2 | -1 | +| -1 | 0 | -1 | -1 | +| -1 | +1 | 0 | 0 | +| 0 | -1 | -1 | -1 | +| 0 | 0 | 0 | 0 | +| 0 | +1 | 1 | +1 | +| +1 | -1 | 0 | 0 | +| +1 | 0 | 1 | +1 | +| +1 | +1 | 2 | +1 | + +The critical property of bundle is that opposing trits cancel to zero, while agreeing trits reinforce. This implements a robust form of distributed consensus — the foundation of VSA's noise tolerance. + +### 28.5.2 FPGA Implementation + +The `vsa_bundle` module mirrors the `vsa_bind` structure but replaces the ternary multiplier with the majority-vote logic. Each position requires one comparison of A[i] and B[i] to detect agreement, disagreement, or zero: + +```verilog +assign result[i] = (a_neg && b_neg) ? 2'b10 : // Both negative: -1 + (a_pos && b_pos) ? 2'b01 : // Both positive: +1 + (a_zero) ? b_trit : // A zero: pass B + (b_zero) ? a_trit : // B zero: pass A + 2'b00; // Opposing: 0 +``` + +Resource cost per bundle trit is approximately 1.5 LUTs (slightly more than bind due to the additional comparison for zero detection). + +## 28.6 Top-Level Integration + +The `vsa_top` module integrates bind, unbind, and bundle behind a unified interface with 2-bit opcode selection: + +| op[1:0] | Operation | Module Instantiated | +|---------|-----------|---------------------| +| `2'b00` | BIND | `vsa_bind` | +| `2'b01` | UNBIND | `vsa_bind` (alias) | +| `2'b10` | BUNDLE | `vsa_bundle` | +| `2'b11` | Reserved | — | + +All three modules operate in parallel on the same input buses `a` and `b`. The `valid_in` signal is gated with the opcode to activate only the relevant module. Output selection uses a delayed opcode register (`op_d`) to align the multiplexer with the 1-cycle pipeline latency of the datapath modules. + +This architecture allows operation switching at full clock rate with zero bubbles — a new operation can be issued every clock cycle, and the result appears exactly 1 cycle later. + +## 28.7 Verification + +### 28.7.1 Testbench Design + +The testbench `tb_vsa_ops.v` verifies all operations at DIM=64 (128-bit bus width) using Icarus Verilog (iverilog v13.0). Ten test cases cover: + +1. **BIND +1 x +1 = +1** — identity multiplication +2. **BIND 0 passthrough** — zero-gate behavior +3. **BIND -1 x +1 = -1** — sign inversion +4. **BIND -1 x -1 = +1** — double negation +5. **UNBIND self-inverse** — bind(a,b) then unbind(result,b) = a +6. **BUNDLE +1 + +1 = +1** — agreement +7. **BUNDLE -1 + +1 = 0** — cancellation +8. **BUNDLE 0 passthrough** — zero-gate behavior +9. **BIND commutativity (A,B)** — forward order +10. **BIND commutativity (B,A)** — reversed order + +Each test applies inputs, waits for the pipeline to flush (2 clock edges plus half-cycle margin), then compares the result against a reference computed by a Verilog function implementing the same algorithm. + +### 28.7.2 Results + +``` +=== VSA Ops Testbench (DIM=64) === +PASS bind_pos_pos +PASS bind_zero_passthrough +PASS bind_neg_pos +PASS bind_neg_neg +PASS unbind_self_inverse +PASS bundle_pos_pos +PASS bundle_neg_pos +PASS bundle_zero_passthrough +PASS bind_commutativity_a_b +PASS bind_commutativity_b_a +=== RESULTS === +PASS: 10, FAIL: 0, ALL TESTS PASSED +``` + +### 28.7.3 Self-Inverse Verification + +Test 5 (unbind self-inverse) deserves special attention as it validates the core VSA decoding property. The test sequence is: + +1. Compute `bound = bind(A, B)` where A = all +1, B = all -1 +2. Compute `decoded = unbind(bound, B)` = `bind(bound, B)` +3. Assert `decoded == A` + +Since bind(+1, -1) = -1 for every position, `bound` = all -1. Then unbind(all -1, all -1) = +1 for every position (because -1 x -1 = +1), recovering the original A = all +1. This confirms that the ternary multiplication hardware correctly implements the self-inverse algebraic property required for VSA symbol decoding. + +## 28.8 Performance Analysis + +### 28.8.1 Latency and Throughput + +The single-stage pipeline design yields: + +- **Latency**: 1 clock cycle (20 ns at 50 MHz) +- **Throughput**: 1 operation per cycle = 50M operations/second +- **Bind bandwidth** (D=10000): 50M x 10,000 trits = 500 billion trit operations/second + +### 28.8.2 Comparison with Software + +| Platform | DIM | Bind latency | Throughput | +|----------|-----|-------------|------------| +| Zig (software, AVX2) | 10000 | ~5 us | 200K ops/s | +| Metal GPU (M1 Pro) | 10000 | ~50 us | 20K ops/s | +| **FPGA (XC7A100T)** | **10000** | **20 ns** | **50M ops/s** | + +The FPGA achieves a 250x speedup over optimized SIMD software and a 2500x speedup over GPU execution for the bind operation, owing to the massive bit-level parallelism that maps directly to LUT hardware. + +## 28.9 Related Work + +The VSA FPGA accelerator described in this chapter differs from prior work in several respects. Plate (1995) introduced Holographic Reduced Representations using circular convolution binding on real-valued vectors — significantly more expensive in hardware than the ternary binding presented here. Kanerva (2009) proposed Binary Spatter Codes using XOR binding on binary vectors, which maps even more directly to hardware but lacks the zero-passthrough and majority-vote properties of balanced ternary. + +The Trinity ternary VSA occupies a middle ground: more expressive than binary VSA (three values instead of two) while remaining efficiently mappable to FPGA logic. The 2-bit-per-trit encoding ensures that each operation requires only a single LUT per trit position — the theoretical minimum for any non-trivial ternary function on Xilinx 7-series devices. + +## 28.10 Canonical Reference + +The FPGA modules described in this chapter are maintained in the `gHashTag/trinity-fpga` repository under `fpga/vsa/`. The canonical VSA specification is `specs/vsa/vsa_core.t27` in the `gHashTag/t27` repository. All test vectors and conformance checks are in `conformance/vsa_core.json`. + +The invariant law L4 (TESTABILITY) mandates that every VSA module includes verification. The 10-test testbench satisfies this requirement, with the self-inverse test (test 5) serving as the critical invariant check for the bind/unbind algebraic property. diff --git a/docs/phd/ch33.md b/docs/phd/ch33.md new file mode 100644 index 00000000..af04ed63 --- /dev/null +++ b/docs/phd/ch33.md @@ -0,0 +1,203 @@ +# Chapter 33: Trinity Stack Integration — Agent ↔ FPGA Cognitive Bridge + +## 33.1 The Integration Problem + +The Trinity S3AI stack spans multiple levels of abstraction: symbolic specifications in `.t27` notation, reference implementations in Zig, GPU compute shaders in Metal, and hardware descriptions in Verilog.

The specification layer defines *what* operations mean; the reference implementation proves *that* they are correct; the hardware compilation translates them into physical logic; the deployment transport delivers the configuration to the target; and the physical target executes the operations at hardware speed. + +## 33.3 VSA as Cognitive Primitive + +The choice of VSA operations as the hardware acceleration target is not arbitrary. In the Trinity cognitive model, the three fundamental VSA operations map directly to cognitive primitives: + +| VSA Operation | Cognitive Function | Analogy | +|---------------|--------------------|---------------------------------| +| **bind** | Association | "This role is filled by that value" | +| **bundle** | Consensus | "The set of things I remember" | +| **unbind** | Decoding | "What filled this role?" | + +An agent that needs to reason about symbolic structures — for example, parsing a natural language sentence into a role-filler representation — performs a sequence of bind operations to encode role-filler pairs, bundle operations to aggregate them into a sentence-level representation, and unbind operations to answer queries about specific roles. Each of these operations operates on hypervectors of dimension D = 10,000, requiring 10,000 parallel ternary computations. + +On a conventional CPU, each ternary operation requires at minimum a conditional branch or lookup table access — approximately 3-5 nanoseconds per operation on a modern processor. For D = 10,000, a single bind takes 30-50 microseconds. On the FPGA, all 10,000 operations execute simultaneously in a single 20-nanosecond clock cycle, a 1500x-2500x acceleration. + +## 33.4 Agent-to-Silicon Pipeline + +### 33.4.1 Specification (t27) + +The canonical VSA specification resides in `specs/vsa/vsa_core.t27`, which defines the balanced ternary type system, the bind/unbind/bundle algorithms, and the invariants (self-inverse, commutativity, zero-passthrough) that any implementation must satisfy. The conformance test vectors in `conformance/vsa_core.json` provide reference inputs and expected outputs for validation. + +### 33.4.2 Reference Implementation (trinity) + +The Zig reference implementation in `trinity/src/firebird/vsa.zig` provides a DIM=10,000 software VSA with the same semantics. This implementation serves dual purposes: (1) as a performance baseline for benchmarking the FPGA acceleration, and (2) as the host-side interface that constructs hypervectors and dispatches operations to the FPGA via the UART protocol defined in `trinity/src/needle/vsa_fpga.zig`. + +### 33.4.3 Hardware Generation (trinity-fpga) + +The Verilog modules in `trinity-fpga/fpga/vsa/` implement the VSA operations as synthesizable hardware.

The ESP32 runs a custom TCP server (port 2542) that translates XVC commands from `openFPGALoader` into physical JTAG signals on the FPGA's configuration pins: + +``` +Host (openFPGALoader) ──TCP:2542──> ESP32 ──GPIO──> FPGA JTAG + │ + WiFi 192.168.1.30 + SSID: Kissmoon50/87_2.4GHz +``` + +The ESP32 XVC server (source: `firmware/xvc-esp32/xvc-esp32.ino`) implements three XVC commands: + +1. `getinfo:` → returns `xvcServer_v1.0:2048\n` +2. `settck:` → sets TCK period (typically 166 ns = ~6 MHz) +3. `shift:` → performs JTAG shift operation + +A critical implementation detail: `openFPGALoader` sends the shift length in **little-endian** byte order. The raw bytes `0x0a 0x00 0x00 0x00` represent 10 bits (LE), not 167 million bits (BE). This endianness mismatch was the primary debugging challenge during initial deployment and is documented in Appendix J. + +### 33.4.5 Physical Execution (XC7A100T) + +The target device is a QMTech XC7A100T-FGG676 development board.

The `.t27` specification language ensures that the *intent* of the VSA operations is preserved through compilation; the conformance vectors ensure that the *semantics* are correct; the FPGA ensures that the *execution* is fast. Each layer contributes a distinct guarantee, and the integration of all layers produces a system that is simultaneously correct, verifiable, and performant. + +The identity phi^2 + phi^(-2) = 3, which serves as the Trinity project's anchor invariant, manifests in this integration as the three-way balance between specification (what), implementation (how), and deployment (where).

The proposed Lattice QCD test for $\alpha_\varphi$ provides a medium-term check. +(Initial JUNO data: November 2025.~\cite{juno2022}) + +% ============================================================ +\section*{Author Contributions} +% ============================================================ + +\textbf{Dmitrii Vasilev:} Conceptualized the Trinity framework, designed the L1--L7 derivation +architecture, introduced $\alpha_\varphi$ as a named constant with 7-step derivation, implemented +the Chimera vectorized search engine, conducted SU(3)/QCD mechanism analysis, and designed the +Monte Carlo permutation test. + +\textbf{Stergios Pellis:} Developed the polynomial $\varphi$-framework achieving sub-ppb precision +for $\alpha^{-1}$, established the comparison criterion for Pellis vs. Trinity precision, +proposed the IR-limit hypothesis (Hybrid Conjecture H1), and contributed CKM Wolfenstein +parametrization~\cite{pellis2021}. + +\textbf{Scott Olsen:} Established the historical and philosophical context of $\varphi$ in physics +from Pythagorean number theory through Bohm's Implicate Order to modern $\varphi$-frameworks, +clarifying the mathematical lineage and its connection to fundamental questions about +physical structure~\cite{olsen2026}. + +\section*{Appendix C.1: Null Result for CHSH Inequality} + +The Trinity framework includes a null result for the Clauser-Horne-Shimony-Holt (CHSH) +inequality~\cite{chsh1969} that deserves explicit statement. + +\paragraph{Null finding:} The Trinity expression for the CHSH parameter $S$ based on +Trinity formulas yields +\begin{equation} + S_{\mathrm{Trinity}} = 2\pi\varphi^{-1}e \approx 2.720 +\end{equation} +where the deviation from the quantum limit $\Delta = S_{\mathrm{Trinity}} - 2\sqrt{2} \approx +$-0.108$ corresponds to a relative error of +\begin{equation} + \frac{|S_{\mathrm{Trinity}} - 2\sqrt{2}|}{2\sqrt{2}} \approx \frac{0.108}{2.828} \approx 3.89\% +\end{equation} +Thus $\Delta \approx 3.89\%$ for the CHSH calculation. This analysis +demonstrates that Trinity cannot reproduce the CHSH quantum violation parameter. + +\paragraph{Interpretation:} The null result for CHSH serves as an important +falsification test: if the Trinity algebraic basis $\{\varphi, \pi, e\}$ were sufficient to capture all +Standard Model phenomena, it would also express quantum entanglement correlations. The failure +to produce $S \approx 2.828$ within quantum uncertainty bounds suggests that the Trinity +framework, while highly successful for classical SM parameters, has limitations for +quantum correlation phenomena. + +\paragraph{Significance:} The CHSH null result ($\Delta \approx 3.89\%$) contrasts with the +high precision achieved for classical SM constants ($\Delta < 0.1\%$). This indicates +that Trinity's strength lies in parameterizing gauge and mixing parameters of the Standard +Model, but does not extend to quantum entanglement observables. + +% ============================================================ +\section*{Acknowledgments} +% ============================================================ + +This work emerged from an email exchange initiated in March 2026 between D.V. and S.P. +following the publication of the Pellis viXra preprint on $\varphi^5$ formulas.
