From 93e283abb348b81d086225f7861d94901c9b0888 Mon Sep 17 00:00:00 2001 From: Nilay Vaish Date: Tue, 11 Dec 2012 10:05:54 -0600 Subject: ruby: add a prefetcher This patch adds a prefetcher for the ruby memory system. The prefetcher is based on a prefetcher implemented by others (well, I don't know who wrote the original). The prefetcher does stride-based prefetching, both unit and non-unit. It obseves the misses in the cache and trains on these. After the training period is over, the prefetcher starts issuing prefetch requests to the controller. --- src/mem/ruby/SConscript | 1 + 1 file changed, 1 insertion(+) (limited to 'src/mem/ruby/SConscript') diff --git a/src/mem/ruby/SConscript b/src/mem/ruby/SConscript index 06f6abd9f..086c2f764 100644 --- a/src/mem/ruby/SConscript +++ b/src/mem/ruby/SConscript @@ -103,6 +103,7 @@ MakeInclude('common/DataBlock.hh') MakeInclude('common/NetDest.hh') MakeInclude('common/Set.hh') MakeInclude('filters/GenericBloomFilter.hh') +MakeInclude('structures/Prefetcher.hh') MakeInclude('system/CacheMemory.hh') MakeInclude('system/DMASequencer.hh') MakeInclude('system/DirectoryMemory.hh') -- cgit v1.2.3
