source: trunk/IPs/systemC/processor/Morpheo/Behavioural/Core/Multi_Execute_loop/Execute_loop/Multi_Execute_unit/Execute_unit/Load_store_unit/src/Load_store_unit_allocation.cpp @ 122

Last change on this file since 122 was 122, checked in by rosiere, 15 years ago

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
