Abstract
PURPOSE:To simplify a circuit constitution by providing a matrix arithmetic means to execute the dividing of the elements of a vector-represented GF(2<m>) as an mXn matrix operation on a GF(2). CONSTITUTION:A modulus 2 adder 8 executes an exclusive logic (exclusive.OR) operation, and a multiplier 9 executes a logic production 9 (AND) operation. Respective elements of 4X4 matrix by A=(a3, a2, a1, a0) are obtained, further, a matrix multiplaying with B=(b3, b2, b1, b0) is executed, and C=(c3, c2, c1, c0) is obtained. Thus, a ROM, which is necessary for obtaining an inverse number, can be replaced with a circuit to use only the modulus 2 adder and the multiplier on the GF(2).
