Abstract

A specialized CAD tool is described that will take a user's high level code description of a non-uniform affinely indexed algorithm and automatically generate abstract latency-optimal systolic arrays. Emphasis has been placed on ease of use and the ability to either force conformation to specific design criteria or perform unconstrained explorations. How such design goals are achieved is illustrated in the context of LU decomposition and the matrix Lyapunov equation. The tool is then used to generate new 1-D and 2-D hardware efficient systolic arrays for the discreet Fourier transform that take advantage of the use of the radix-4 matrix decomposition.
