METHOD AND APPARATUS FOR LATCHING DATA WITHIN A DIGITAL SYSTEM

摘要

One embodiment of the present invention provides a system for latching data in response to a clock signal. This system includes a memory element that is configured to store a data value. A latch input is coupled to the memory element, so that changes in the latch input change the data value stored in the memory element without waiting for an assertion of the clock signal. The system also includes a driver circuit that is configured to drive the data value stored in the memory element onto a latch output. The system additionally includes a clocking circuit that is configured to cause the driver circuit to drive the data value stored in memory element onto the latch output in response to an assertion of the clock signal.
