Abstract:
In one embodiment, a microprocessor includes fetch logic for retrieving an instruction, decode logic configured to identify a plurality of operands and a multiply operation specified in the instruction, and execution logic configured to receive the plurality of operands and the multiply operation. The execution logic includes a first logic path configured to perform the multiply operation on the plurality of operands and output a result, and a second logic path, arranged in parallel with the first logic path, configured to output metadata associated with the result of the multiply operation.
