WebReducing Conflict Miss Rates Technique 3: High associativity caches – More options for block placement → fewer conflicts – Reduce conflict miss rate – May increase hit access time because tag match takes longer – May increase miss penalty because replacement policy is more involved Web•Reducing Miss Rate 1.

Reduce Misses via Higher Associativity • 2:1 Cache Rule: – Miss Rate DM cache size N ≈ Miss Rate 2-way cache size N/2 • Beware: Execution time is only final measure! – Will Clock Cycle time increase? – Hill [1988] suggested hit time for 2-way vs. 1-way external cache +10%, internal + 2% ray stowell

Higher associativity WebTherefore, reducing the miss rate of a level-one cache for embedded system microprocessors can greatly reduce the total power consumption. The CAM-based HAC [3][9] is specifically designed for low power embedded systems where performance (cache ... The other is the high associativity.
