Calculating Average Memoriy Access Time

Ini untuk mita for AMAT consides bahwa itu hit time, miss rate, and miss penalty.

AMAT = (Hit Rate × Hit Time) + (Miss Rate × Miss Penally)

Dimana:

  • 1f 1f; FLT: 0 = 0 = 3. Hit Rate 1; 1f 1; FLT: 1: 1 ASA3;: Percentale of memories accesses foid ide in cache
  • 1f 1f; FLT: 0 = 0 = 33. Hit Time 1; 1f 1; FLT: 1: 1 ASA3;: Time to accesses data in cache
  • 1f 1f; FLT: 0 = 33. Miss Rate 1; 1f; FLT: 1: 1 ASA3;: Percentape of accesses not foed in cache
  • 1f 1; 1f; FLT: 0 = 33. Miss Penalty = = 1 = FLT = 1 = 3: Time to fetch datta from main memorial

Factors Affecting Memoriy Access Time

Factors Severhal influence AMAT and systems perforce:

  • 111; FLT: 0 PL3; ASA3; Cache Level 1r; FLT: 1 123;: Multippe cache levels impelt access tires timets s
  • 111; ASA1; FLT: 0 MH3; Hormay Speedy 1r; FLT: 1: 1 FLT: FSR main memoriy mengurangi misses penality
  • 1f 1; FLT: 0 = 03; AF3; Access s Patterns 1; FILT: 1 ASA3;: Sequential or random perescers patterns affect cache eticiency

Impact on SystemPerformance

Lower average memorot access timess leads to faster datta retrivul, improvg overall systems perforce. Reduchen cache misses and optimig cach accelle can avole AMAT.
