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
