Dear Sir/Ma'am,
In SOC size of interconnections between multiple processors is very small. So is it possible to have one big size central cache for all processors ignoring access time.
I know processors share cache memories with other processors by using interconnections.
But can we make an SOC that have a single central cache for all processors. If we can do this what will be its disadvantages other than longer access time.
The whole point of caches is to help with speed. If you are ignoring speed then just get rid of the cache. The disadvantage of a cache when you ignore speed is that it is a waste of space and effort.
Actually i want to know can we have any advantages/disadvantages in mapping. Or resources present on single cache. I know all about speed problems. Hope you understand.
