PURPOSE:To improve the retry success rate of an instruction by using a soft visible register, where error does not occur, to write data again. CONSTITUTION:When a soft visible register 1 is read by software and is used for operation or the like, error is reported to an error processing circuit 100 to suppress the execution of software if error is detected by an error detecting and reporting circuit 3. Simultaneously, contents of the soft visible register 1 or a copy soft visible register 2 are selected as rewrite data in a selecting circuit 6 by error information reported to a rewrite control circuit 5, and a rewrite update signal 51 of the soft visible register 1 and the copy soft visible register 2 is outputted. Thereafter, a rewrite completion signal 53 is outputted to the error processing circuit 100. |
