Abstract

PURPOSE:To retry an instruction which has caused an error by holding the instruction by pipeline interlocking, and by reporting the error after the execution of a preceding group of all instruction is completed. CONSTITUTION:In decoding an instruction in the state D of a phase A, if an error is detected in one of bytes of a code OP, an OR circuit 24 outputs a ''1'', and an FF31 is set. When the FF31 is set while a plus enable signal is a ''1'', an AND circuit 27 outputs a ''1'' and the instruction having caused the error is forced to a pipeline interlocking state, thereby holding the instruction in the phase A. If the FF31 is set here, an AND circuit 26 outputs a ''1'' unless a pipeline is cleared while the phase A is valid, and the ''1'' is inputted to the circuit 24 to hold the error state. Then, the error is reported after the execution of a preceding group of instructions is completed.
