Program state word history recording system
专利汇可以提供Program state word history recording system专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain data for investigating the cause of a fault by logging out the history information of a program state word (PSW) written in a storing means before the point of time of the occurrence of an undesirable event to the log-out area of a main storage device, and holding it.
CONSTITUTION: The PSW related to an instruction in the course of execution at present from the program area 21 of the main storage device 20 is written successively in a PSW history recording buffer through a present PSW register 31, and old PSW register 32 and a write-in register 39. When the undesirable even such as a hardware fault or program exception occurs, the PSW recorded in the PSW history recording buffer 38 is read out, and is transmitted to the log-out area 22 of the main storage device 20 through a read-out register 37, and history before the point of time of the occurrence of the undesirable event is logged out and held. Thus, trouble whose cause is unknown such as the hardware fault and the defect of software, etc., can be investigated.
