Automated design and descriptive tools are essential for the practical application of highly parallel special-purpose hardware such as systolic arrays. The use of special-purpose hardware can greatly increase the capabilities of signal processing systems. However, the more limited applications base makes design costs a critical factor in determining technical and economic viability. Systolic systems can be described at several levels of abstraction, each of which has unique descriptive requirements. This paper focuses on the descriptive issues involved at the system architectural level. Tools at this level must bridge the gap between logic- and circuit-oriented computer-aided design tools and algorithmic descriptions of systolic architectures. Traditionally, hardware description languages (HDLs) have been used at this level to describe conventional computer architectures. Systolic architectures, however, have different requirements. This paper examines these requirements and develops a set of criteria for evaluating HDLs. Four popular DHLs are evaluated and their strengths and weaknesses noted. The final section of the paper summarizes ongoing efforts at Los Alamos to develop a systolic array HDL based on the CONLAN family of languages. 14 references.
