Changeset 504 for trunk/platforms/tsar_generic_xbar

Timestamp:

Aug 30, 2013, 6:28:10 PM (11 years ago)

Author:

meunier

Message:

• Added activity counters to the vci_mem_cache
• Modified the print_trace function accordingly
• Refactored code in vci_mem_cache because there was a mix of 2-space and 4-space indentation
• Modified topcell to factorize ALMOS specifications

Location:

trunk/platforms/tsar_generic_xbar

Files:

• soclib.conf (modified) (1 diff)
• top.cpp (modified) (18 diffs)
• top.desc (modified) (1 diff)
• tsar_xbar_cluster/caba/source/src/tsar_xbar_cluster.cpp (modified) (1 diff)
