Abstract
A method of configuring a hardware design for a pipelined parallel stream processor includes obtaining a scheduled graph representing a processing operation in the time domain as a function of clock cycles. The graph includes a data path to be implemented in hardware as part of the stream processor, an input, an output, and parallel branches to enable data values to be streamed therethrough from the input to the output as a function of increasing clock cycle. The data path is partitioned into a plurality of discrete regions, each region operating on a different clock phase and having discrete control logic elements. Phase transition registers to align data separated by a boundary between regions having different clock phases are introduced into the data path at the boundary. The graph and control logic elements define a hardware design for the pipelined parallel stream processor.
