Copy&Paste GAF.

CSM (Coherent Shared Memory) is useful for multicore systems whereby they can all share the same location at once, so for example if 1 of the 8 cores changes the information in the memory location the other 7 cores are working using out of date information stored in their cache.

hUMA is basically so the CPU and GPU can share data between each other so the cpu doesnt have to copy the information to memory and the gpu copy it out, then copy it back to memory then the cpu can copy it out.
