Embedded Memory Allocator Suite

A production-style modular memory management framework written in ANSI C for embedded systems.

---

Overview

Embedded Memory Allocator Suite is a production-inspired memory management library developed in ANSI C for embedded systems. The project demonstrates multiple dynamic memory allocation algorithms, fragmentation analysis, heap visualization, memory profiling, and reusable allocator APIs.

The project has been designed with modularity, portability, readability, and embedded-system best practices in mind, making it suitable as both a learning resource and a portfolio-quality systems programming project.
