Explanation of Statistics/3
The R12000 processor gives additional information:
- Miss handling table occupancy:
- average number of entries in MHT. A higher value indicates more outstanding cache misses. An interesting observation is to get
-
-
- it should be ɭ, since if it is close to 1 there might be dependency in the data that prevents the processor to issue multiple outstanding cache misses
- it could be ə for code that fits into the cache
- high values for Mh while the memory bandwidth is low would indicate a lot of L1 misses into the same L2 cache line
-
- Prefetch miss rate:
- rate of prefetch instructions missing in the first level cache
-
-
- should be close to 1: Every prefetch to be effective should miss in the cache.
