STATICALLY SCHEDULABLE FEED AND DRAIN STRUCTURE FOR SYSTOLIC ARRAY ARCHITECTURE

A systolic array implemented in circuitry of an integrated circuit includes a processing element array including processing elements. The systolic array includes one or more feeder circuits communicatively coupled to the processing element array. Each of the one or more feeder circuits includes a first section configured to receive data stored in memory external to the integrated circuit, and a second section configured to send the received data to the processing element array, wherein data transferring from the memory to the processing element array is double buffered by the first section and the second section. The systolic array also includes one or more drain circuits communicatively coupled to the processing element array, including one or more memory buffers configured to store data output by the processing element array.
