Message:

Erasing useless template parameters for the communication/dspin_dhccp_param class.

Modifying consequently the vci_mem_cache_dspin_coherence class to use the
dspin_dhccp_param class without templates.

Introducing in the vci_mem_cache and the vci_mem_cache_dspin_coherence modules
the state CAS_DIR_HIT_COMPARE.

Before this modification, the comparison between the expected data and the actual
data was done directly in the CAS_DIR_HIT_READ state using the data obtained in the
same cycle from the cache.

Now, the data obtained from the cache is stored in a buffer and the next cycle,
in the CAS_DIR_HIT_COMPARE state, the comparison is made using the data from the
buffer.

This modifications allows to eliminate a critical path obtained in the ASIC
synthesis of the memory cache.
