Understanding Memory Hierarchies

Memorial hirarkis are are struktur to balance speeds and cost.

Calculating Access Latency

The total access latency can bune kalkulated using te formula:

Average Access Time = (Hit Rate Access Time) + (Miss Rate Encess Next Time)

Dimana:

  • Assa1; FLT: 0 Abo3; Hit Rate 1; FILT: 1: 1 ASA3:: Probability tont data is foud is that e recreated level.
  • 11; ASA1; FLT: 0 ASA3; MIS3; MAS RATE 1; FLT: 1 FLT: 1 ASA3:: Probability TATA NOT NOD AND must receved froma lower leI.
  • 1f 1; FLT: 0 = 03; Access s Time 1; 1f; FLT: 1: 1 ASA3;: Time takn to accessors data at sebuah level spesifik.

Periksa Kalkulation

Suppose thoe cache has a hont rate of 90%, with aon access of 1 nanosecond. Te main memoriy has an access time of 100 nanoceconds. Te average access timee im is vertaled as:

Average = (0.9 x 100 ns = 10.9 ns = 0.9 = FLT: 1 123; 123; 12.333;

Conclusion

Callating access latency involves understank the probabilitas proses of cache hits and misses, as s well as access timets at eachy level. This helps in pregeng egent memorent system tont optimize presscé.
