Subject : CC2202 : Computer System Architecture Lab/Tutorial : Session 5: Cache Subject Lecturer : Steven Chan 1 ) Consider a memory system with the following parameters: Access Time of C (T c )= 100 ns Cost of C (C c )= 0.01 cent/bit Access Time of M (T m )= 1200 ns Cost of M (C m )= 0.001 cent/bit (Note: c = Cache Memory, m = Main Memory) a. What is the cost of 1 MBytes of main memory? b. What is the cost of 1 MBytes of using cache memory technology? c. What is the effective access time and it’s relation with hit ratio H? d. If the effective access time is 10% greater than the cache access time, what is the hit ratio H? e. In the case mentioned in d, what is the overall cost per bit? 2) For the hexadecimal main memory addresses 111111, 666666, BBBBBB, show the following information, in hexadecimal format: a. Tag, Line, and Word values for a direct-mapped cache, using the given format. a.
