Changeset 122 for trunk/IPs/systemC/processor/Morpheo/Behavioural/Core/Multi_OOO_Engine/OOO_Engine/Rename_unit/Load_Store_pointer_unit/src/Load_Store_pointer_unit_transition.cpp

Timestamp:

Author:

Message:

Modif for performance :
1) Load Store Unit : store send request to valid exeception
2) Commit_unit : retire can bypass store
3) Commit_unit : add stat to manage store instruction
4) Load Store Unit and Load Store Pointer Manager : add store_queue_ptr_read
5) Fix lot of bug
