IA Core Level 1 and Level 2 Caches

The first level cache is divided into a data cache and an instruction cache. The processor first level cache size is 32 KB for data and 32 KB for instructions. The first level cache is an eight way associative cache and is parity protected.

The second level cache holds both data and instructions. The L2 cache size is 1.5 MB and is a 12 way associative cache. It is shared across the four cores in the module and is ECC protected (1-bit correct and 2-bits detect).
