23 - when freeze or stall; don't let memory operations
- Modification on the CP0
- The CP0 is deplaced in the WB stage
- The INT, SI event signals are treated asynchronously in the WB stage
- The rCAUSE register is asynchronous now
- The wException signal is asyncronous instantanously
- Add a repeat/continous treatement (not completed yet)

- *** The "INT EXCEPTION NO STALL" work correctly

22 - Some modifications for testing exception. ameziti 5974d 23h /
21 - Flush must be on all signals in the pipeline. ameziti 5974d 23h /
20 - Modification of CP0 to wait the end of all stalls before to process Exception.

- except the asynchronous event like "external interruption"

18 - Read/Write of the CP0 register is in the WB stage, but Exception detection begin from the MEM stage. ameziti 5975d 13h /
17 - UnFonctional Modifications: Change the name of the address port of "CP0". ameziti 5975d 14h /
16 - Remove All generable files from the project. ameziti 5975d 21h /

10 Modification of the CP0. ameziti 5976d 08h /
9 When D-Cache miss, there's no need to stall MEMWB and freeze WB.
The solution is to flush MEMWB only.
ameziti 5976d 08h /
8 Enhancement of the "Controler specification doc". ameziti 5979d 08h /
7 Add Pipeline Controler specification documentation. ameziti 5980d 06h /
6 When D-Cache miss, there's no need to stall MEMWB and freeze WB.
The solution is to flush MEMWB only.

5 Remove the Multiple Arithmetic Unit fonction.
- The Pipeline must stall when Mult/Div unit is busy.
- Whether there's a mflo or mfhi.
- see `define MULTIPLE_ALU
