Ross Thompson	cedb234013	Turns out the merge of dirty and tag bits is complicated by the need to have byte write enables rather than bit write enables. Putting on hold for now.	2022-11-30 11:01:25 -06:00

Ross Thompson	faa13a96e0	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

Ross Thompson	42111db671	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
