Load_store_unit.h @ 78

Last change on this file since 78 was 78, checked in by rosiere, 16 years ago

Add :

Execute_loop (must be test systemC)
Prediction
- Direction : predifined scheme
- Branch Target Buffer
iFetch_unit
- ifetch_queue
- pc management
Decod_unit
- coming soon : support for custom operation
Rename_unit
- RAT
- Free_list
- Dependence RAW check
- Load store unit pointer
New Environnement (hierarchy_memory will remove in a next version)

Modif :

Manage Custom Operation
All component in execute_loop to use the new statistics management

Not Finish :

Return Address Stack
Environnement
