Abstract
PURPOSE: To enable the continuity of processing and the point out of the error position, by reading out correct data from the main memory immediately after the parity error is caused in the high speed buffer memory.
CONSTITUTION: When the parity error is detected in the buffer memory, the error flip flop 13 is set. Further, the instruction counter 19 is set to the address causing parity error at this time. Next, the address causing error data from the main memory is fetched by referencing the instruction counter. The data from the main memory is outputted to the bus 10 and the content is compared with the data causing the parity error at the comparison circuit 6. The result compared in bit correspondence is set and displayed on the error display register 17. Simultaneously, the error flip flop is reset and the instruction sequence is executed.
