A program consists of 500 instructions in total, including a loop of 100 instructions that is executed 25 times. Initially, all instructions are stored in main memory, and the cache is empty.
Assume:

  • Main memory access takes 10 units of time
  • Cache access takes 1 unit of time
  • The cache is large enough to hold all loop instructions
  • Program execution time depends only on the time taken to fetch instructions (operand data access is ignored)

What is the speedup achieved by using the cache?
Provide your answer as a numerical value rounded to 2 decimal places.
