A Computer system with a cache has a physical memory with
, a hit ratio of
65 percent
, and an
average memory access time of
Tm = 39.9ns
. What is access time for the cache?
Computer system has a cache with
Tc = 10ns
, physical memory with
Tp = 55ns
, and physical memory with
access time
Tm = 40ns
. What is the hit ratio?
A Computer system has a cache with
Tc = 10ns
, a hit ratio of
80 percent
and an average memory access time
Tm = 24ns
. What is the access time for physical memory?
cache hit
cache miss
. A cache system has a 95 percent hit ratio, an access time of 100 nsec on a
cache hit and an access time of 800 nsec on a cache miss. What is the effective access time?
A cache is being designed for a computer with 2
bytes of memory. The cache will have 2K slots and use a 16
byte block. Compute for both an associative cache and a direct
mapped cache how many bytes the cache will
