27 The design doesn't work correctly. ameziti 5512d 11h /r2000/trunk
24 New directory structure. root 5649d 02h /r2000/trunk
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		 ameziti 6007d 11h /trunk
22 - Some modifications for testing exception. ameziti 6042d 04h /trunk
21 - Flush must be on all signals in the pipeline. ameziti 6042d 04h /trunk
20 - Modification of CP0 to wait the end of all stalls before to process Exception.
- Set "Exception sign" active until all Stalls are completed.		 ameziti 6042d 11h /trunk
19 - Exception signals must be stalled, flushed, stoped or cleared(except reset)
- Look at 14-07-2007
- except the asynchronous event like "external interruption"		 ameziti 6042d 17h /trunk
18 - Read/Write of the CP0 register is in the WB stage, but Exception detection begin from the MEM stage. ameziti 6042d 18h /trunk
17 - UnFonctional Modifications: Change the name of the address port of "CP0". ameziti 6042d 18h /trunk
16 - Remove All generable files from the project. ameziti 6043d 01h /trunk
15 - UnFonctional Modifications.
- Change the "CP0" define to "EXCEPTION".		 ameziti 6043d 03h /trunk
14 Remove unnecessary files from project. ameziti 6043d 11h /trunk
13 - To simplify the exception traitement: Instruction are executed serialy.
- Exception event must be treated CONCURRENTLY with the other event that stall the pipeline.		 ameziti 6043d 11h /trunk
12 To simplify the exception traitement: Instruction are executed serialy. ameziti 6043d 12h /trunk
11 Exception event must be treated CONCURRENTLY with the other event that stall the pipeline. ameziti 6043d 12h /trunk
10 Modification of the CP0. ameziti 6043d 12h /trunk
9 When D-Cache miss, there's no need to stall MEMWB and freeze WB.
The solution is to flush MEMWB only.		 ameziti 6043d 12h /trunk
