how to count caches
Posted: Sun Jul 07, 2013 8:58 am
hi folks,
i'm writting CPUID program. i need help with cache counting. i know, that cpuid leafs 02h and 04h(for Intel) and 80000005, 6h (for AMD) gives me how much CPU has got cache and it's details, but i need know how many of specified sort caches there are. For example:
Intel Core i7-3820
Level 1 cache size 4 x 32 KB instruction caches
4 x 32 KB data caches
Level 2 cache size 4 x 256 KB
Level 3 cache size 10 MB
as it is described above - this cpu has got 4 times 32 KB instruction cache. how to get the number of times for specified sort of cache.
thanks in advance
