ARITHMETIC PROCESSOR AND ARITHMETIC PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the power consumption of a convolution encoding processing and to improve the speed of the processing. SOLUTION: An AND circuit 104 fixes output to '0' when the value of a register 6 is '0' and outputs the value of a shift register 4 as it is when the value of the register 6 is '1'. An AND circuit 105 fixes output to '0' when the value of the register 6 is '0'. The AND circuit 105 outputs the value of a selector 12 as it is in the case of an initial stage when the value of the register 6 is '1' and outputs the value of a selector 102 in (i-1)-th stage is outputted as it is in the case except for the initial stage.
