Changeset 429 for trunk/modules/vci_mem_cache/caba

Timestamp:

Jul 1, 2013, 1:54:12 PM (12 years ago)

Author:

cfuguet

Message:

Modifications in vci_mem_cache:

• Modifying MULTI_ACK_IDLE state to verify also that in the case of WRITE FSM request, the update table index is valid (this is already the case for a CC_RECEIVE request).

• Fixing some indentation and non desired spaces

File:

• trunk/modules/vci_mem_cache/caba/source/src/vci_mem_cache.cpp (modified) (68 diffs)
