PROBLEM TO BE SOLVED: To provide a matrix arithmetic processor capable of quickly executing a matrix arithmetic operation in a small circuit scale. SOLUTION: An input signal data column I is temporarily stored in a reg 12, and inputted to an adder in response to an instruction from a control means 10. The control means 10 instructs an ROM 11 in which a check matrix H is stored to obtain a position where '1' is erected in a certain column of the check matrix. The ROM 11 instructs selectors SEL1 #1 to #CW to select values corresponding to the position of 1 in the check matrix from among values from a reg(M) 13, and to transmit the values to the adder. The added values are selected by selectors SEL2 instructed by the ROM 11, and inputted to the reg(M) 13. As for non-added values, the output values of the reg(M) 13 are inputted as they are, or inputted through the selectors SEL2 to the reg(M). This process is repeated until all the arithmetic operations end. COPYRIGHT: (C)2004,JPO
