Abstract:
1. A method of performing a floating-point operation with a floating-point processor operable to perform floating point operations having a first precision, the method comprising: determining a subprecision less than the first precision for the floating-point operation, wherein the subprecision is determined based on information included in an executable instruction to perform the floating-point operation, the information indicating a number of selected bits of at least one input operand associated with the floating-point operation, and wherein the subprecision corresponds to the number of selected bits and the number of selected bits is less than a width associated with the at least one input operand; removing power from a portion of logic circuitry to prevent processing of unselected bits of the at least one input operand associated with the floating-point operation; and performing the floating-point operation at the subprecision using powered portions of the logic circuitry to generate a resulting output.
