Title: Memory access controller
Inventor: SUGIYAMA HIROFUMI
IPC: G06F12/16
Filed: 1992-01-22
Abstract: PURPOSE:To relieve the fault of a diagnostic processor having a lot of steps with high probability by executing retry to a request when any error is generat ed at a request processing part. CONSTITUTION:When error is generated in a request processing at any one of input/output devices 1, 2 and 3, an error signal is outputted and when a device number is outputted from the outputted error signal, the processing of the request from any one of the input/output devices 1, 2 and 3 shown by the device number is made invalid. The processing of the invalid request is waited at a waiting circuit or the request is executed again inside just by the set number of times for retry. Therefore, when any fault is generated, the diagnostic processor judges whether the fault is an intermittent fault to be relieved by a software or a fixed fault not to be relieved and when the retry is executed by the software because of the intermittent fault to be relieved, the number of steps is considerably reduced for the capacity of microinstructions without considering the fault processing in the case of the intermittent fault for the software of the diagnostic processor.
