Branch_Target_Buffer_allocation.cpp @ 112

Last change on this file since 112 was 112, checked in by rosiere, 15 years ago
1) Stat_list : fix retire old and new register bug 2) Stat_list : remove read_counter and valid flag, because validation of destination is in retire step (not in commit step) 3) Model : add class Model (cf Morpheo.sim) 4) Allocation : alloc_interface_begin and alloc_interface_end to delete temporary array. 5) Script : add distexe.sh 6) Add Comparator, Multiplier, Divider. But this component are not implemented 7) Software : add Dhrystone
