Abstract

PURPOSE:To validate a required part easily in a high speed, by retrieving contents of an error state holding part by a validate timing signal to validate contents of a data holding mechanism where an error occurs. CONSTITUTION:When a parity error occurs in a register 3-2 during the data processing, it is reported to an error processing part 1. If it is discriminated that retry is necessary, it is reported to a validate timing signal generating processing part 2, and a logical ''1'' is outputted to a validate timing signal line 7, and the register 3-2 is cleared, and retry becomes possible. Consequently, even if a decode circuit for the error signal and a path for data load are not provided, only a required part is validated easily in a high speed.
