sectoralloc-allocator

Experimental bitmap-based memory allocator written in pure C.

Overview

sectoralloc-allocator is a low-level allocator designed around:

• sector-based memory organization,
• bitmap-driven allocation,
• deterministic memory traversal,
• fixed-size pages and blocks,
• reduced fragmentation-oriented allocation strategies.

The allocator currently targets:

• embedded systems,
• RTOS-oriented environments,
• low-level systems programming,
• custom runtime experimentation.

Architecture

Memory layout:

• 64 sectors
• 32 pages per sector
• 4096-byte pages
• 16-byte blocks

Allocation search hierarchy:

1. sector bitmap
2. page bitmap
3. page block bitmap

The allocator supports:

• fragmented allocation search,
• tail allocation search,
• linear sequential allocation,
• atomic sector locking.

Current Status

Early experimental stage.

Implemented:

• core allocator structures,
• bitmap hierarchy,
• sector/page metadata design,
• allocation model planning.

In progress:

• allocation logic,
• free(),
• synchronization validation,
• fragmentation handling,
• stress testing.

Goals

• deterministic allocation behavior,
• low-overhead metadata,
• predictable traversal,
• RTOS-friendly architecture,
• portable ISO C implementation.
