Abstract:
A method and apparatus for performing a floating-point operation with a floating-point processor having a given precision is disclosed. A subprecision for the floating-point operation on one or more floating-point numbers is selected. The selection of the subprecision results in one or more excess bits for each of the one or more floating-point numbers. Power may be removed from one or more components in the floating-point processor that would otherwise be used to store or process the one or more excess bits, and the floating-point operation is performed with power removed from the one or more components.
