I think this code should be left here. Because the total access latency now depends on both tag_latency and data_latency, the value of the 'lat' parameter specifying the access latency is not correct when the accessBlock() function is called. As a result, the 'lat' value should be updated inside the function depending on if it is a sequential or parallel access. > On juin 27, 2016, 5 après-midi, Nikos Nikoleris wrote: > > src/mem/cache/tags/fa_lru.cc, line 212 > > <http://reviews.gem5.org/r/3502/diff/8/?file=56392#file56392line212> > > > > Same here Same here - Sophiane ----------------------------------------------------------- This is an automatically generated e-mail.
