ABSTRACT:
In some embodiments of the present invention, one or more elements of a processor core may receive a signal indicating that operands of a micro-instruction are narrow, for example less than or equal to 32 bits. In response to this signal, one or more components of a processor core element that are able to handle more than 32 bits of data (e.g. operands or results) may function as though they handle only 32 bits of data.
