Code Optimisation Questions
Loop fusion is a code optimization technique that involves combining multiple loops into a single loop. This is done by merging the iterations of two or more loops that operate on the same data or have similar computation patterns.
By fusing loops, redundant computations and memory accesses can be eliminated, resulting in improved code performance. Loop fusion reduces the overhead of loop control structures and loop index calculations, leading to fewer instructions executed and improved cache utilization. It also enables better loop vectorization and parallelization opportunities, as the combined loop can have a larger iteration space and more regular memory access patterns. Overall, loop fusion helps to minimize the number of instructions executed and optimize memory access, leading to faster and more efficient code execution.
