Loop unrolling is a compiler optimization technique that increases a program's execution speed by decreasing the overhead of loop control code and increasing the pipeline throughput. By expanding the loop body multiple times, it reduces the number of iterations and allows for more efficient use of the CPU's instruction pipeline and registers.

An instruction pipeline is a technique used in modern CPUs to improve instruction throughput by overlapping the execution of multiple instructions. By dividing the execution process into distinct stages, each part of the pipeline can work on different instructions simultaneously, enhancing overall performance and efficiency.

Registers are small, high-speed storage locations within a CPU that temporarily hold data and instructions being processed. They play a critical role in the execution of programs by allowing quick access to frequently used values and intermediate results, thus enhancing the overall performance of the processor.
