There are many different ways to solve this problem. It
really depends what you are trying to do. In case of cashes
or MMUs, the good old TLBs are used. If you must allocate
internal memory for passing through data blocks for such
applications where you have to do bandwidth matching for
example, you can simplify the problem. I used a separate
piece of memory to hold the pointers and the equivalent of
the "malloc header" (of course all optimized for hardware
and my specific problem). To avoid fragmentation nightmares,
make sure you always allocate memory in fixed min size blocks.
If possible only support one block size ...
