Code Optimisation Questions
Loop splitting is a code optimization technique that involves dividing a loop into multiple smaller loops. This technique helps in code optimization by improving cache utilization and reducing loop overhead.
By splitting a loop, the code can be organized in a way that allows for better utilization of the CPU cache. This is because smaller loops have a higher chance of fitting entirely within the cache, reducing the number of cache misses and improving overall performance.
Additionally, loop splitting can help in reducing loop overhead. Loop overhead refers to the extra instructions and computations required for loop control, such as loop condition checks and loop variable updates. By splitting a loop into smaller loops, the loop overhead is reduced as each smaller loop has its own loop control, resulting in fewer instructions and computations.
Overall, loop splitting is a code optimization technique that improves cache utilization and reduces loop overhead, leading to better performance and efficiency in the code.
