10.3.5.1. Cache Latency

Latency for cache hits and misses varies.

The latency for an L1 cache hit is 1 clock. The latency for an L1 cache miss and L2 cache hit is 6 clocks best case. Latency in the L2 cache can vary depending on other operations in the L2. Parity and ECC settings have no effect on latency. A single-bit ECC error is corrected during the L2 read, but is not re-written to the L2 RAM.
