Abstract: A mechanism to generate a self-clock within a synchronous processing unit of an asynchronous digital device. The self-clock is designed to match the worst-case delay of pipeline processing unit in such a way that the pipeline processing unit is operate at its own natural clock frequency and shutting off when there is no valid data to process. The synchronization logic of the processing unit consists of self-clock that generates output clock to synchronize with the internal clock edge if the processing unit is active or synchronize with the input clock edge if the processing unit is inactive.
