SEMICONDUCTOR DEVICE, INFORMATION PROCESSOR, AND DATA PROCESSING METHOD THEREIN

PROBLEM TO BE SOLVED: To solve the problem in which a conventional semiconductor device is not able to compensate for a worst case at the time when a live lock state continues.SOLUTION: According to one embodiment, in a semiconductor device, data processor, and data processing method therefor, when a lock acquisition process is performed such that while maintaining the coherence of target process data, one of a plurality of arithmetic logic parts eliminates the influence of the processes of the other arithmetic logic parts on the target process data, the one arithmetic logic part brings the subsequent instruction after the cancellation of a lock state with respect to the target process data into a standby state for a predetermined wait period.
