ABSTRACT:
An operation circuit for performing either fixed or floating point mathematical operations, having a mode control function for a multiplier including a multiplier, an arithmetic logic unit (ALU) and a signal generating circuit. A signal specifying the operating mode of the ALU, either a fixed point mode or a floating point mode is used by the signal generating circuit for generating either a fixed point multiplication signal or a floating point multiplication signal to control the multiplier, respectively.
