Message:

Modifications in branches/v5/vci_mem_cache:

• Changing name of CC DSPIN ports: + p_dspin_in => p_dspin_p2m + p_dspin_out => p_dspin_m2p

• Splitting the Update Table in two tables: + UPT (Update Table): Stores the MULTI-UPDATE transactions + IVT (Invalidate Table): Stores the MULTI/BROADCAST INVALIDATE

transactions

Each table has its own allocator FSM: r_alloc_upt and r_alloc_ivt
