ABSTRACT:
A multiplying circuit for forming a partial product in accordance with a Booth's algorithm, performing a sign correcting process of the partial product, and adding the partial product so as to multiply a multiplicand by a multiplier, includes: initial value setting circuit for setting an initial value and for supplying data necessary for the sign correcting process and adding circuit for adding the partial product and data supplied from a preceding circuit. The initial value setting circuit is adapted to output the data necessary for the sign correcting process in a format where the data accords with at least a part of a data input format of the adding circuit. In the adding circuit at least a part of a data input format of data thereof is the same as at least a part of a data output format thereof. According to the multiplying circuit, in the initial value setting circuit, data necessary for a sign correcting process, that is, calculating the complement of 2, of a partial product is converted into a format compatible with a data input format of an adding circuit. The resultant data is supplied to the adding circuit.
