IA Cores Level 1 and Level 2 Caches

P Cores 1st level cache is divided into a data cache (DFU) and an instruction cache (IFU). The processor 1st level cache size is 48KB for data and 32KB for instructions. The 1st level cache is an 12-way associative cache.

E Cores 1st level cache is divided into a data cache (DFU) and an instruction cache (IFU). The processor 1st level cache size is 64KB for data and 32KB for instructions. The 1st level cache is an 8-way associative cache.

The 2nd level cache holds both data and instructions. It is also referred to as mid-level cache or MLC. The P Cores 2nd level cache size is 1.25MB and is a 10-way non-inclusive associative cache., 4 E Cores processors share 2MB 2nd level cache and is a 16-way non-inclusive. associative cache.

Hybrid Cache

Notes:
  1. L1 Data cache (DCU) - 48KB (P-core) - 64KB (E-Core)
  2. L1 Instruction cache (IFU) - 32KB (P-Core) - 32KB (E-Core)
  3. MLC - Mid Level Cache - 1.25MB (P-Core) - 2MB (shared by 4 E-Cores)
