Abstract
The present invention relates to a data processor, and particularly in a data processor performing condition execution on the basis of flag information, aims at obtaining a data processor having excellent code efficiency, which can reduce branch penalty. In order to attain the aforementioned object, it is so structured that, when a first instruction decoded in a first decoder is an execution condition specifying instruction specifying the execution condition for a pair of second instructions executed in parallel, a first execution condition determination unit performs determination of the execution condition for the second instructions defined by the execution condition specifying instruction on the basis of the flag information and controls assertion/non-assertion of an execution inhibit signal on the basis of whether the execution condition defined by the execution condition specifying instruction is satisfied or not.
