Abstract
A microprocessor synchronously executes instructions, the instructions including integer instructions for performing integer operations and floating point instructions for performing real number operations. An instruction pipeline has a plurality of successive stages for synchronously executing each of the instructions in parallel, with integer and floating point instructions being intermixed in the pipeline. Each of the plurality of successive stages simultaneously operates on a different one of the instructions. An integer unit executes the integer instructions and forms an integer result based on an integer operation performed on at least one integer operand or integer result. A floating point unit executes the floating point instructions and forms a floating point result based on one such floating point operation performed on at least one floating point operand or floating point result. A data path is shared by the integer unit and the floating point unit for communicating between the plurality of successive stages in the instruction pipeline integer operands or the integer results and the floating point operands or the floating point results.
