Prefetching : access time reduction
- miss prediction => increasing mem traffic / cache pollution
- is it advanced enuf? >> address might be right, but it might still take more time
- if early enuf, might pollute cache, prefetched line might replace/may be replaced.
metrics to evaluate : achieved performance (number of misses, total traffic and IPC), coverage and accuracy
