The Memory Manager

The manager will init it self if there is no blocks, the manager is model after a LinkedList and not a List.

Memory Layout

The layout has not preset list or table but rather every item has meta data linking the next and prevuis item this allows for a robust system.

The data layout looks as follow :

Object|Object|Object etc.

Object =

Meta Data|Data

Meta data =
4 bytes(preveus block address start)|4 bytes(curent[this] block address start)|4 bytes(next block address start)|4 bytes(curent[this] block size)

the final layout looks like this:

4 bytes|4 bytes|4 bytes|4 bytes | (size of object) bytes  |  4 bytes|4 bytes|4 bytes | 4 bytes | (size of object) bytes  | etc

Note: this means the smallest size an object can ocupy is 17 bytes, 16 bytes for the header and 1 for the smallest data type a byte.

How this system is used.

Allocation

Adding an object is easy, you simply find the first free block using compare exchange and split it.

Deallocation (free)

Freeing ablock is easy set its size(in meta data) to 0
