Changeset 111 for trunk/IPs/systemC/processor/Morpheo/Behavioural/Core/Multi_Front_end/Front_end/Prediction_unit/Update_Prediction_Table/src/Update_Prediction_Table_allocation.cpp

Timestamp:

Message:

1) Decod_queue : multi implementation (one_fifo, multi_fifo)
2) Issue_queue : multi implementation (in_order, out_of_order)
3) Direction : Add Meta predictor
4) Context_State : re add Branch_complete, More priority to Load miss (is not speculative)
5) Return_Address_Stack : update reg_PREDICT pointer on decod miss prediction
6) UPT : Fix bug in multi event
7) Prediction_glue : in read_stack case, insert in UPT pc_next
8) Rename select : when rob have an event (need flush), read_r{a,b,c} and write_r{d,e} is set at 0
