Abstract
In a renormalization processing device of MQ-CODER, the value of an augend register A is calculated by a shift quantity calculating unit without performing loop processing, and the number of left shifts SHIFT_A of A up to the end of renormalization processing is calculated. The renormalization processing device judges whether byteout processing or bytein processing occurs or not, on the basis of the positive or negative sign of (SHIFT_A-CT) and the value of CT. When byteout/bytein processing occurs, the values of a code register C and a free byte counter CT that are immediately before the occurrence of processing are found. When byteout/bytein processing does not occur, the values of C and CT that are after the end of normalization processing are found. If the value of (SHIFT_A-CT) is a positive value after byteout/bytein processing, this value is substituted in SHIFT_A and renormalization processing is performed again.
