What is loop splitting and how does it improve code performance?

Loop splitting is a code optimization technique that involves dividing a loop into multiple smaller loops. This technique aims to improve code performance by reducing the number of iterations performed in each loop, thereby reducing the overall execution time.

By splitting a loop, the code can be parallelized, allowing multiple iterations to be executed simultaneously on different processors or threads. This can lead to significant performance improvements, especially on multi-core or multi-threaded systems.

Additionally, loop splitting can help improve cache utilization. By dividing a large loop into smaller ones, the data accessed within each loop can fit more efficiently into the cache, reducing cache misses and improving memory access times.

Overall, loop splitting improves code performance by enabling parallel execution and optimizing cache utilization, resulting in faster and more efficient execution of the loop.
