本発明はデータ処理システムのメモリ破壊発見方式に関
し、特にプログラムバグ等によってメモリの記憶内容が
破壊されたときのデバグ手段に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for detecting memory corruption in a data processing system, and more particularly to a debugging means when the contents of a memory are corrupted due to a program bug or the like.
従来、この種のデバグ手段は、パネル等にデバグモード
として命令のオペランドアドレス−数機能があったが、
小型のシステムにおいては無い場合が多い。Conventionally, this type of debugging means had a debugging mode on a panel, etc., with an instruction operand address-number function.
This is often absent in small systems.

う欠点があった。As mentioned above, in a system without an instruction operand address/number function, if the memory is destroyed due to something like Progera's baldness, generally the instruction step has progressed considerably, or many f-r events occur. Then the system will go down. At this time, a memory dump is taken to analyze the problem, but as mentioned above, since a considerable amount of time has passed since the memory was destroyed, problem analysis is not easy.

とを含んで構成される。The configuration of the memory corruption detection method of the data processing system of the present invention includes, in the data processing system, an event detection means for detecting an event that occurs asynchronously, and a preset memory address and data that are monitored when the event occurs. memory corruption monitoring means; monitoring data setting means for setting the address and data of the memory to be monitored in the memory corruption monitoring means; and data processing when the memory address and data match by the memory corruption monitoring means. The system includes a system stop means for stopping the system.

ムの運転を停止する。As mentioned above, when a system goes down, a memory dump is taken and analyzed, but if this system down is due to memory corruption, at least the memory corruption and the corrupted data address can be known from the memory dump. Generally, if the cause cannot be determined from this memory dump, a reproduction test is performed. According to this embodiment, during this reproduction test, the memory corruption address and destruction data predicted from the dump results are set in advance by the monitoring data setting means 3. Each event that occurs during system operation is detected by the event detection means 1, and the memory corruption monitoring means 2 is activated. The memory corruption monitoring means 2 monitors memory corruption from preset addresses and data. When no memory corruption has occurred, the system is returned to normal operation, and when memory corruption has occurred, the system stop means 4 is activated to stop the system operation.
