ac0f6ddb7b I found the issue with the cache changes. FlushW is not asserted for all TrapM. Ecall and Ebreak don't flush the W stage. However the ifu's bus controllable must disable the BusRW for all traps. 2022-11-16 15:38:37 -06:00

5f7b0b8a9b Oups found a bug with my cache changes. I took TrapM out of the logic path for selecting the cache's address CAdr (previously RAdr) to improve the critical path. This is fine for the dcache because both the E and M stages are flushed. However for the ICache only F is flushed. PCNextF is valid and points to XTVEC so the cache must take NextAdr rather than PAdr as CAdr. 2022-11-16 12:36:58 -06:00
