From 322b9ca2c5b0465db7086abdc6eadca061932575 Mon Sep 17 00:00:00 2001 From: Lisa Hsu Date: Thu, 31 Mar 2011 17:17:57 -0700 Subject: Ruby: Add new object called WireBuffer to mimic a Wire. This is a substitute for MessageBuffers between controllers where you don't want messages to actually go through the Network, because requests/responses can always get reordered wrt to one another (even if you turn off Randomization and turn on Ordered) because you are, after all, going through a network with contention. For systems where you model multiple controllers that are very tightly coupled and do not actually go through a network, it is a pain to have to write a coherence protocol to account for mixed up request/response orderings despite the fact that it's completely unrealistic. This is *not* meant as a substitute for real MessageBuffers when messages do in fact go over a network. --- src/mem/protocol/RubySlicc_Types.sm | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/mem/protocol') diff --git a/src/mem/protocol/RubySlicc_Types.sm b/src/mem/protocol/RubySlicc_Types.sm index add3d979b..7d444ab57 100644 --- a/src/mem/protocol/RubySlicc_Types.sm +++ b/src/mem/protocol/RubySlicc_Types.sm @@ -146,6 +146,10 @@ structure (CacheMemory, external = "yes") { void setMRU(Address); } +structure (WireBuffer, inport="yes", outport="yes", external = "yes") { + +} + structure (MemoryControl, inport="yes", outport="yes", external = "yes") { } -- cgit v1.2.3
