Short notes: Improved Matrix Product Computation using Double-Pipeline Systolic Arrays
Graham M. Megson · The Computer Journal · 1988
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.
