Message-ID: <20041008173155.52028.qmail@web52901.mail.yahoo.com> (raw)
Consider a two-level memory hierarchy system M1 & M2.
M1 is accessed first and on miss M2 is accessed. The
access of M1 is 2 nanoseconds and the miss penalty
(the time to get the data from M2 in case of a miss)
is 100 nanoseconds. The probability that a valid data
is found in M1 is 0.97. The average memory access time
will be how much?
if somebody can solve this?
thanks
ankit
