9869b26556 Fixed the multliple reads of the same preload memory file. 2023-06-13 13:52:02 -05:00

df62f3964c The testbench now at least runs the arch64i in rv64gc config. Still has several issues 
1. need to remove all dead code
2. seems to still be double reading memory files sometimes.
3. batch mode does not work.

918464c236 Found the coremark performance issue. The testbench was continuously forcing the BTB to all zeros. Once fixed it resolved the performance problem. 2023-06-05 15:42:05 -05:00

Fixes bug 203 and linux/ImperasDV mismatch at 571M instructions
 2023-05-30 13:37:00 -07:00
Ross Thompson
8e1476cb8c Possible fix for Linux bug and bug 203. ImperasDV mismatches in linux boot around 571M instructions after the login prompt. 
This bug occurs when there are back to back HPTW requests and the first generates an access fault during the walk. The old implementation uses a delayed version of the fault to prevent the HTPW fsm from transitioning out of the IDLE state.  Because the first request generates the fault and the second request is pipelined the second request appears as if it also faults so the FSM does not perform the walk.
The new implementation adds a FAULT state.  When the HPTW generates an access fault it transitions to this state removes the HPTWStall and then transitions to IDLE.  There may still be a remaining bug here if the pipeline is stalled for another reason.  However I don't think it is possible by construction.  The only possible sources of stalls at this point would be IFU and LSU stalls and both are required to make this condition happen.

1315a0bf4a Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check. 2023-05-26 16:00:14 -05:00
