ABSTRACT:
A system for binary multiplication in a superscalar processor includes a first pipeline, an execution unit, and a first multiplexer; a first rotator in communication with one register of the first pipeline and the execution unit; and a leading zero detection register in communication with the execution unit and another register of the first pipeline; a second pipeline, a second execution unit, and a second multiplexer; a rotator in communication with one register of the second pipeline and the second execution unit; and a leading zero detection register in communication with the second execution unit and another register of the first pipeline; and a third pipeline, a binary multiplier in communication with a pair registers of the third pipeline; a general register; an operand buffer for obtaining first and second operands; and a bus for communication between the pipelines, the general register and the operand buffer.
