Instruction Cache Miss Rates
Explanation of Axes : The x-axis shows increases the cache size,
from 4 KB to 2 MB. For each cache size, there are still many parameters
to vary. Associativity is varied with a different color of line; for
example, a direct-mapped cache (associativity = 1) is represented by a
green line, and a 16-way associative cache by a light blue line. How do
we vary block size? Well, each line (for a particular cache size and
associativity) is comprised of a number of distinct points. Each point
represents a different block size, from 8 bytes up to an unusually large
IRAMish 2 KB. Thus, each cache size on the graph has 5 lines associated
with it (one for each associativity), and each line has 9 points
associated with (one per block size).
Since these are the traffic results, the y-axis shows the miss rate
(in a percentage) that occured during the course of a simulation.
The first figure shows the results for tomcatv.
The second figure shows the results for claxpjf.
The last figure shows the results for sql95.
