PROCESSOR CIRCUIT PROVIDED WITH 1ST PROCESSOR, AND SYSTEM PROVIDED WITH THE SAME AND 2ND PROCESSOR

摘要

PURPOSE: To provided a processor circuit of a prescribed type for simplifying the diagnosis of error frequently generated in a test phase by providing a specified dual memory means. CONSTITUTION: The processor circuit(PC card) 6 includes with a dual memory means (DPR circuit) 11 equipped with a 1st parallel address input 14 linked to a parallel address output 29 of a 1st processor (68302 processor) 27, 1st parallel data input/output 15 linked to a parallel data input/output 28 of the processor 27, 2nd parallel address input 12 linked to a parallel address input 7 of the card 6, and 2nd parallel data input/output 13 linked to a parallel data input/ output 8 of the card 6. Then, the error existent in the processor 27 and further belonging to a certain category is stored in the DPR circuit 11 at the position (address field) as the function of the category to which the error belongs to. Therefore, the error can be easily diagnosed.
