Abstract
A processor achieving a zero-overhead loop, includes instruction stream control circuitry and loop control circuitry. The loop control circuitry includes loop address detecting circuitry and loop end determining circuitry. By combining instructions and hardware, the loop control circuitry eliminates additional control instructions required b each loop iteration and can achieve loop acceleration with zero overhead, thereby improving the loop execution efficiency.
