ABSTRACT:
Apparatus and a method for providing a single instruction that can load a character from memory and perform a character compare. In an illustrative embodiment, this is accomplished by providing indexing apparatus which permits indexing on character boundaries. The characters are loaded from memory, and provided to an ALU unit in a processor, wherein a compare is made with a desired value. The ALU provides a compare result to a jump skip logic block, which notifies the processor whether the instruction immediately following the instruction of the present invention should be skipped or executed.
