Low latency nodes fusion in a reconfigurable data processor

Abstract

A data processing system includes an array of reconfigurable units and a compiler configured to generate a pipeline of n computational nodes related to a dataflow graph, interleaved between n+1 buffers on the array of reconfigurable units. Each computational node is coupled to perform calculations based on data received from an immediately preceding buffer of the n+1 buffers and store results of the calculations into an immediately following buffer of the n+1 buffers after a latency. The compiler is further configured to remove a buffer of the n+1 buffers from the pipeline based on a comparison of the latencies of the computational nodes. A corresponding method is also disclosed herein.
