Abstract
We describe a systematic method for the design of systolic arrays. This method may be used for algorithms that can be expressed as a set of uniform recurrent equations over a convex set D of Cartesian coordinates. Most of the algorithms already considered for systolic implementation may be represented in this way. The methods consists of two steps: finding a timing-function for the computations that is compatible with the dependences introduced by the equations, then mapping the domain D onto another finite set of coordinates, each representing a processor of the systolic array, in such a way that concurrent computations are mapped onto different processors. The scheduling and mapping functions meet conditions that allow the full automation of the method. The method is exemplified on the convolution product and the matrix product.

Translating systolic arrays into instruction systolic arrays
CSC '88: Proceedings of the 1988 ACM sixteenth annual conference on Computer scienceAn instruction systolic array is a programmable systolic array. Instructions and mask bits are pumped through the array as well as data. It offers cost-benefit advantages over systolic arrays because one array can be used for multiple applications. This ...
