Abstract

A method and apparatus that converts integer numbers to/from floating point representations while loading/storing the data. The method and apparatus perform this conversion within a central processing unit having a converter unit and a set of conversion registers. The load/store instructions having data requiring conversion include an index field for identifying one of the conversion registers. Each one of the conversion registers includes information on the type of conversion required and any scaling factors to be applied. Upon receiving one of these instructions, the converter uses the identified conversion register to perform the conversion and stores the converted data into the corresponding register or memory location.
