MCQ: Per memory reference, miss-rate can be turned into per instruction misses rate by

  1. Miss rate= Memory accesses/ instructions
  2. Miss rate= Memory accesses* instructions
  3. Miss rate= Memory accesses-instructions
  4. Miss rate= Memory accesses+ instructions

A

MCQ: When Cycle per instruction is 1.0, data accesses are 50% of total instructions, and miss penalty is 25clock-cycles and miss rate having 2%, then computer would faster as,

  1. 1.25
  2. 1.45
  3. 1.75
  4. 1.85

C

MCQ: Address spaces are typically broken into fixed-size blocks, called

  1. Registers
  2. Stacks
  3. Pages
  4. Frames

C

MCQ: Processor's performance can be calculated as

  1. CPU execution time = (CPU clock cycles - Memory stall cycles) ? Clock cycle time
  2. CPU execution time = (CPU clock cycles + Memory stall cycles) ? Clock cycle time
  3. CPU execution time = (CPU clock cycles + Memory stall cycles) - Clock cycle time
  4. CPU execution time = (CPU clock cycles x Memory stall cycles) + Clock cycle time

B

MCQ: Ratio of cache accesses, results in a miss is known as

  1. Hit miss
  2. Hit rate
  3. File caches
  4. Miss rate

D
