in my system \r\nE$ is 32.0 , how to interpret this 32 ??

race

32M\r\nUltraSPARC Ⅳ+的CPU

Lainhearter

UltraSPARC IV:\r\nPrimary (L1): 64 KB 4-way data, 32 KB 4-way instruction, 2 KB Write, 2 KB Prefetch\r\nSecondary (L2): 16 MB external (exclusive access to 8 MB per pipeline), On-chip controller and address tags \r\nUltraSPARC IV+:\r\nPrimary (L2): 2 MB on-chip\r\nSecondary (L3): 32 MB off-chip \r\n这个32M的是L3CACHE

race

可以通称为L2,CPU内部的叫on-chip，外部的cache叫off-chip
