Code Optimisation Questions
Loop peeling is a code optimization technique that involves removing a small number of iterations from the beginning or end of a loop. This technique is typically used when the loop has a fixed number of iterations and the number of iterations is known at compile-time.
Loop peeling helps in code optimization by reducing the overhead of loop control instructions and improving the efficiency of the loop. By removing a few iterations from the loop, the loop control instructions are executed fewer times, resulting in faster execution. Additionally, loop peeling can also help in improving cache utilization and reducing branch mispredictions, leading to further performance improvements.
Overall, loop peeling is a simple yet effective optimization technique that can significantly enhance the performance of loops with a fixed number of iterations.
