Memory Partitioner
==================

Memory Management
=================

* Replaces malloc() and free()
* malloc and free has some drawbacks, especially in embedded devices.

  * Increased code size
  * Now determistic behavior
  * Fragmentation problems, small block of data
    scattered in memory prevent allocation of large blocks.

* uCos provides a partion memory allocator.

  * No fragmentation problem
  * Runs at a constant time
  * Are deterministic

Memory Control Blocks
=====================

* Manages a memory partion
* Number of blcoks is set by OS_MAX_MEM_PART in os_cfg.h
* Held in the OSMemFreeList until used.
