We present a pipelined inversion/division circuit in Galois field using AB2 circuit technique (where both A and B are elements in the finite field). We use composite Galois fields in a multiple-valued logic (MVL) approach to minimize the inversion/division circuit needed for binary Galois fields. The overall design, which connects basic cells in a systolic manner, thereby making effective use of pipelining, is shown. The fact that less literals are used speeds up the calculation operation. Also, our circuit shows a significant amount of savings in both transistor count and connections, which is so important in VLSI. In this review important patents are also discussed.
