Abstract
A processor is disclosed including several features allowing the processor to simultaneously execute instructions of multiple conditional execution instruction groups. Each conditional execution instruction group includes a conditional execution instruction and a code block specified by the conditional execution instruction. In one embodiment, the processor includes multiple state machines simultaneously assignable to a corresponding number of conditional execution instruction groups. In another embodiment, the processor includes multiple registers for storing marking data pertaining to a number of instructions in each of multiple execution pipeline stages. In another embodiment, the processor includes multiple attribute queues simultaneously assignable to a corresponding number of conditional execution instruction groups. In another embodiment, the processor includes write enable logic and an execution unit. The write enable logic produces write enable signals dependent upon received attributes, and the execution unit saves results of instructions of conditional execution instruction groups dependent upon the write enable signals.
