Abstract

PURPOSE:To detect the abnormality of an equipment by classifying a memory read request, a response to this request, and an instruction for reading data stored in a data buffer into respective two kinds depending on whether they are issued at the start of operation or at the end in order to check whether data read out from the data buffer is proper or not. CONSTITUTION:At a time when the final data of operation is inputted, a memory operand and final information are stored in the data buffer 40. And a control storage part 1 recognizes the data to be the final of the operation, and issues a final buffer read instruction to read the memory operand stored in the buffer 40. At this time, if final response information corresponding to the memory operand is not present, the read memory operand is not the final data, hence the abnormality of the equipment is decided on.
