f4d778c2f6 Corrected the LSU's fsm for stalling CPU. Removed state from hptw fsm. 2021-12-19 15:10:33 -06:00

a445bedcd2 Modified the icache memory to read using the virtual (non physical) address in the PCNextF stage. 
This allows recovering from an ITLBMiss to be 1 cycle after and simplifies the hptw slightly.
