ABSTRACT:
Several designs of a stage for use in a FIFO pipeline are disclosed. Each stage includes a latch that is capable of latching a data element and capable of transitioning between a transparent state and an opaque state. The stages also include a control circuit capable of announcing the availability of the data element to the next stage as soon as the data element has propagated through the latch and without any latching or unlatching action of the latch prior to the announcement of the availability of the data element. In other words, if the latch of a stage is transparent and receives a signal Ri from the previous stage, the control circuit of the stage generates signal Ro after receiving signal Ri, thus enabling the next stage to latch the data element before the current stage has itself latched that data element. This feature is possible because the next stage receives at the input Din of latch block the same data element that appears at the input Din of the current latch block when the current latch block is transparent.
