Improved Matrix Product Computation using Double-Pipeline Systolic Arrays

G. M. Megson1 * and D. J. Evans2

1 Loughborough University of Technology, Loughborough, Leicestershire, LE11 3TU, UK, 2 Rutherford Appleton Laboratory, Chilton, Didcot, Oxon, UK

A volume-efficient retimed hexagonal array for computing matrix product is described. The new array requires the same time as the well-known hex array of Kung and Leiserson but uses only half the hardware. The design is separated out on to two planar layers which communicate with each other only at the array boundaries, and requires the same number of input–output connections as the traditional array. Individual cells compute with an efficiency of e = 2/3.

Received October 1987.

* Dr Megson is now Joint Atlas research fellow, Oriel College, Oxford University; correspondence about this paper should be addressed to him at Rutherford Appleton Laboratory, Chilton, Didcot, Oxon.
