Wave pipeline including synchronous stage

Abstract:

A wave pipeline includes a data path and a clock path. The data path includes a plurality of wave pipeline data stages and a synchronous data stage between a data input node and a data output node. The synchronous data stage includes a first data latch to latch the data from the synchronous data stage. The clock path includes a plurality of clock stages corresponding to the plurality of wave pipeline data stages between an input clock node and a return clock node. Each clock stage has a delay configured to be equal to a delay of the corresponding wave pipeline data stage. The wave pipeline includes a second data latch to latch the data on the data output node in response to a return clock signal on the return clock node. The first data latch latches the data from the synchronous data stage in response to a clock signal on the clock path.
