Zusammenfassung:A method and apparatus for processing multi-cycle instructions include picking a multi-cycle instruction and directing the picked multi-cycle instruction to a pipeline. The pipeline includes a pipeline control configured to detect a latency and a repeat rate of the picked multi-cycle instruction and to count clock cycles based on the detected latency and the detected repeat rate. The method and apparatus further include detecting the repeat rate and the latency of the picked multi-cycle instruction, and counting clock cycles based on the detected repeat rate and the latency of the picked multi-cycle instruction.
