发明名称 Converting an arbitrary fixed point value to a floating point value
摘要 A method and apparatus are provided for performing efficient conversion operations between floating point and fixed point values on a general purpose processor. This is achieved by providing an instruction for converting a fixed point value fx into a floating point value fl in a general purpose processor. Accordingly, the invention advantageously provides a general purpose processor with the ability to execute conversion operation between fixed-point and floating-point values with a single instruction compared with prior art general purpose processors that require multiple instructions to perform the same function. Thus, the general purpose processor of the present invention allows for more efficient and faster conversion operations between fixed-point and floating-point values.
