  • Patent number: 6237085
    Abstract: A processor includes execution resources and condition code logic. The execution resources execute an arithmetic or logical instruction by arithmetically or logically combining at least two operands. Concurrent with the execution of the arithmetic or logical instruction by the execution resources, the condition code logic determines less than, greater than, and equal to condition code bits associated with the result of the arithmetic or logical instruction. In one embodiment, the condition code logic includes a single computation stage that receives as inputs individual bit values of bit positions within first and second operands and logically combines the individual bit values. The single computation stage outputs, for each bit position, propagate, generate, and kill signals that collectively indicate values for the less than, greater than, and equal to condition code bits.
