Applied Program Bungle Detection Apparatus and Method by Interrupt

摘要

The present invention for detecting an error in the application, the error detection apparatus according to the application using interrupts according to the present invention includes a central processing unit for the overall control and treatment in the board; Comparison logic to check whether the task is a normal operation is carried out according to the instruction of the central processing unit, and outputs an error detection signal; A memory controller for outputting a memory control signal for controlling the memory receives the error detection signal from the compare logic, and; Receiving the memory control signal from the memory controller, it is configured to include a memory for storing or deleting data.; On the other hand, the error detection method of the application using interrupts according to the invention, comprising a boot and board, recorded in the operating system is allocated the task ID to perform the operation area; Further comprising: a task ID to the decoder by the recorded task ID latching the data bus, and the task ID to determine the task group generates N signals; Step in which the task corresponding to the task ID is running; The method comprising operation in accordance with the task in a given area, searches for each yirueojineunga; The searching result of operation in accordance with the task yirueojyeoseo outside the predetermined area to generate a grant signal to zero is interrupted; Characterized in that it comprises the step of identifying an error in the program at the time when the interrupt occurred occurred and correct the error.; According to the present invention it is, that the page-by-page ever memory write protection, are difficult to find out the reason for the application and the error is exactly the error occurs when there is an error in the program occurs on the line, by the behavior of the application by detecting only hardware addition of simple comparison logic, it does not violate the allocation area for each task given by generating an interrupt signal to accurately communicate information to the memory and the application that caused the current problems in the CPU to handle the error the effect is expected.
