Last change on this file 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
