Last change on this file since 117 was 117, checked in by rosiere, 15 years ago

1) Platforms : add new organization for test
2) Load_Store_Unit : add array to count nb_check in store_queue
3) Issue_queue and Core_Glue : rewrite the issue network
4) Special_Register_Unit : add reset value to register CID
5) Softwares : add multicontext test
6) Softwares : add SPECINT
7) Softwares : add MiBench?
7) Read_queue : inhib access for r0
8) Change Core_Glue (network) - dont yet support priority and load balancing scheme
