From 6fc0094337bc0356c55232c3850fb5fd2dab1f0c Mon Sep 17 00:00:00 2001 From: Mrinmoy Ghosh Date: Tue, 25 Sep 2012 11:49:41 -0500 Subject: Cache: add a response latency to the caches In the current caches the hit latency is paid twice on a miss. This patch lets a configurable response latency be set of the cache for the backward path. --- tests/configs/realview-o3-checker.py | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'tests/configs/realview-o3-checker.py') diff --git a/tests/configs/realview-o3-checker.py b/tests/configs/realview-o3-checker.py index b263adee0..56990eb54 100644 --- a/tests/configs/realview-o3-checker.py +++ b/tests/configs/realview-o3-checker.py @@ -46,7 +46,8 @@ import FSConfig # ==================== class L1(BaseCache): - latency = '1ns' + hit_latency = '1ns' + response_latency = '1ns' block_size = 64 mshrs = 4 tgts_per_mshr = 20 @@ -58,7 +59,8 @@ class L1(BaseCache): class L2(BaseCache): block_size = 64 - latency = '10ns' + hit_latency = '10ns' + response_latency = '10ns' mshrs = 92 tgts_per_mshr = 16 write_buffers = 8 @@ -69,7 +71,8 @@ class L2(BaseCache): class IOCache(BaseCache): assoc = 8 block_size = 64 - latency = '50ns' + hit_latency = '50ns' + response_latency = '50ns' mshrs = 20 size = '1kB' tgts_per_mshr = 12 -- cgit v1.2.3
