摘要
A processor is disclosed including an instruction unit and an execution unit. The instruction unit fetches and decodes instructions, including a conditional execution instruction. The conditional execution instruction specifies one or more instructions to be conditionally executed (i.e., “target instructions”), a register of the processor, and a condition within the register. When the instruction unit fetches and decodes the conditional execution instruction, the execution unit saves results of the one or more target instructions dependent upon the existence of the specified condition in the specified register during execution of the conditional execution instruction. A system including the processor is described, as is a method for conditionally executing at least one instruction.
