Memory allocator

I developed a custom memory allocator in C that efficiently manages dynamic memory allocations using a metadata structure for each memory block. It supports both malloc and calloc, and implements techniques for managing fragmentation, including coalescing free blocks to reduce external fragmentation.

Overview

Memory Management Strategies

• Used brk() for small allocations and mmap() for large allocations.
• Implemented best-fit allocation to minimize fragmentation.
• Block splitting and coalescing to optimize memory reuse.

Performance Enhancements

• Heap preallocation to reduce syscall overhead.
• Metadata structure (block_meta) for tracking memory blocks efficiently.
• Memory alignment (8 bytes) for better access performance.
