Brief Explanation:
This program demonstrates various techniques for the code optimization. As you know there is so many ways to optimize a program; here we intend just to include those techniques that mostly are related to the architecture of modern CPUs. We try to take advantage from things like the pipeline hole reduction in CPU's function units. The program written as an assignment for the "Advanced Computer Architecture" course, Fall 2000.

You will find example codes to validate the following techniques:

• Loop Unrolling
• Loop Collapsing
• Inlining
• FPU Optimization
• Strength Reduction
• Tail Recursion
• Column Major
• Loop Inversion
• Unswitching
• Loop Jamming/Fusion

"Calculating PI" and "Finding Maximum Value in an Array" have presented as case studies to show how we may use the techniques in existing codes.
