This paper gives a fundamental theory of a systolic array, which is a high-performance special-purpose processor. The connection interface between processor elements (PEs) that is required in order for it to realize a regular cubic systolic array (RCSA) has been discussed. RCSA is a three-dimensional array on a cubic lattice of single-type PEs having identical cubic shapes and identical connection interfaces of a one-to-one mapping. As the result, we have shown the necessary and sufficient condition for realizing RCSA: The connection interface between PEs is such that each surface of PE is connectable to only one surface.
