Abstract

PURPOSE:To permit retry of an instruction which causes an error despite the generation of the intermittent error detected at the inlet of a pipeline at any point of time. CONSTITUTION:When an error is detected in the instruction and the inlet of a pipeline, a phase A error tag FF 28-A is set by an OR circuit 24, and when a + phase A release goes on, a phase B error tag FF 28-B is set. In this way, the error tag shifts successively to FFs 28-B, 28-C, 28-D, 28-E, 28-F. When the + phase F release goes to a ''1'' while the phase F error tag 28-F is set, an FF 30 is set, and error reporting is carried out.
