Chapter 11, Problem 15RETC

Explanation of Solution

Code Optimization:

Optimization of code requires various techniques which can be applied to a specific situation.

In many instances a set of instructions are performed repeatedly which are added to a loop and the control keeps passing from start to end and then back to start after each iteration.

• Loop Fusion: A technique that attempts to merge loops operating on the same set of data and the cache memory is exploited to its full capacity is called loop fusion. This reduces the value of loop control of loop overhead such as maintenance.
• Loop Fission: Loop fission is the technique in which larger loops are broken up into more managable loops which decreases the possibility of data dependency...
