摘要： The ability to harmonize the activities of individual computer system components with control signals is key to the operation of any computer system. Examples of this need for control include the need to write data to multiple registers on the same clock cycle, the need to clear values on multiple entities on the same clock cycle, and the need to stop and start the master clock pulse train itself. In the past, providing this control was not a problem because control signals could be reliably sent to all the timing dependent components within a single cycle of the master clock pulse train. This control methodology is called "single cycle control." Today, however, single cycle control is not trustworthy in all situations. Master clock pulse trains are so fast that single cycle control is no longer reliable when timing dependent components reside in locations distant from the control signal generating circuitry. The present invention provides reliable control in all cases, including the situation where a master clock pulse train is so fast that single cycle control is not viable.
