How to find size of Cache memory i.e. L1 and L2
 

Hi,

1)I need to know if there is a C function which could find out how much cache memory(i.e. L1 and L2 Cache) is available in a processor.
I want to find the cache(L1 & L2) availability from a C program.

2) How can I find the access time of L1 cache, L2 cache and main memory?


Thanks.
