Problem: After graduating, you are asked to become the lead computer designer at Hyper Computers, Inc. Your study of usage of high-level language constructs suggests that procedure calls are one of the most expensive operations. You have invented a scheme that reduces the loads and stores normally associated with procedure calls and returns. The first thing you do is run some experiments with and without this optimization. Your experiments use the same state-of-the-art optimizing compiler that will be used with either version of the computer. These experiments reveal the following information:
The clock rate of the un optimized version is 5% higher.
Thirty percent of the instructions in the un optimized version are loads or stores.
The optimized version executes two-thirds as many loads and stores as the un optimized version.
For all other instructions the dynamic execution counts are unchanged.
All instructions (including load and store) take one clock cycle
