9868e685a4 Minor cleanup of cache. 2022-07-19 23:04:23 -05:00
Ross Thompson
6c8ac7851e Reverted to fetched the demand cache line first then doing the eviction. This is important because of an optimization in the replacement policy. The replacement policy updates the LRU 1 cycle late and reads the LRU 1 cycle late for critical path timing. This means doing the eviction first requires an initial 1 cycle delay but this delay has to be applied to all misses because we don't know if an eviction is required. Since reading the demand line first is logically ok so long as it is not written to the sram until after the eviction. 2022-07-19 22:42:25 -05:00
