Allocating Memory

mcgeezer · 30 March 2018, 21:24

Hi all,

I have a quick question around allocating chip memory on Amiga's.

My game requires around 350Kb of chip memory to run.

Will I gain greater compatibility if I ask the system for all 350Kb in one go or is it better to ask for individual small chunks, each related to the size of the
required assets?

Does the Amiga defragment memory to keep large contiguous spaces or am I over thinking this?

Any help appreciated.

The allocations are more likely to be successful if you ask for individual small chunks. If you ask for a single 350K chunk, it will fail unless a contiguous 350K chunk is available.

Amiga has massive memory fragmentation problems. Use a few large chunks if possible but avoid requiring a single slab.
