摘要：
A 3-bit condition execution field in an condition execution instruction stores an encoded value obtained by encoding a condition stored in an general purpose flag indicating to execute the condition execution instruction. A microprocessor has an instruction decode unit 2 comprising a condition execution decode section 401 for decoding a value in the condition execution field and a condition execution judgement section 402 for judging whether or not the decoded result from the condition execution decode section 401 is equal to a condition stored in general purpose flags, and outputting the indication to execute the condition execution instruction when both are equal.
