Abstract

In a data processor, the conditions associated with an operand are evaluated only in response to the execution of a special instruction. The results of this evaluation is provided as a result operand and stored in a general purpose destination register. The evaluated conditions are each provided in discrete form, that is, unencoded, rather than in encoded form.
