Hello,
Taking the common/Caches.py as an example:
class L1Cache(BaseCache):
assoc = 2
hit_latency = 2
response_latency = 2
block_size = 64
mshrs = 4
tgts_per_mshr = 20
is_top_level = True
class L2Cache(BaseCache):
assoc = 8
block_size = 64
hit_latency = 20
response_latency = 20
mshrs = 20
tgts_per_mshr = 12
write_buffers = 8
Let's say the data we're referencing is in L1. The total latency is 2 or (2
+ 2) ? Same question if the data is in the L2 (and not the L1), the total
latency is 20, (2 + 20), (20 + 20) or (2 + 20 + 20 + 2) ?
Does the latency affect read misses or both read and write misses?
Thanks for the clarifications.
Best regards,
Maxime.
