Message:

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

File:

• trunk/IPs/systemC/processor/Morpheo/Behavioural/src/Signal_link.cpp (modified) (4 diffs)
