Embodiment Construction

[0035] Such as figure 1 As shown, a fault monitoring and processing device based on virtual interrupt is proposed, which is characterized in that it includes: a fault monitoring and reporting module, a system-level fault scheduling module, a system-level default fault processing module, a partition virtual interrupt controller module, and a partition fault processing module. Table, partition default fault processing module, task fault processing table, task fault processing module, user-level fault scheduling module;

[0036] The fault monitoring and reporting module is capable of discovering faults that occur in the system during system operation and reporting to the system-level fault dispatching module; in this embodiment, the fault discovery mechanism may include processor hardware interrupts and internal exceptions, A system operation detection module in the operating system, and a fault detection module for user applications;

[0037] The system-level fault scheduling m...

Abstract

The invention relates to a failure monitoring processing device based on virtual interruption and a method. For the purpose that a computer user can process the fault after the processor is abnormal under the user state of the processor in a safe key system, the failure monitoring processing device based on virtual interruption provided by the invention comprises a fault monitoring reporting module, a system-level fault scheduling module, a system-level default fault processing module, a partition virtual interruption controller module, a partition fault processing table, a partition default fault processing module, a task fault processing table, a task fault processing module and a user-level fault scheduling module. When the system running is in fault, under the condition of confirming as a user fault, the used fault processing module is confirmed through the query task fault processing table and the partition fault processing table, the fault processing module is taken as a partition virtual interruption processing function and the system can enter into the processor user state so as to perform corresponding fault processing.

Description

technical field [0001] The invention belongs to the use technology of an embedded computer, and in particular relates to a fault monitoring and processing device and method based on a virtual interrupt. Background technique [0002] For safety-critical systems, an important function of the operating system is to isolate and recover from faults, so that the user's application tasks will not spread to affect the system in the event of a fault, and at the same time provide users with fault recovery methods. means. [0003] Fault isolation can be achieved by the time determinism and space isolation of the operating system. Time determinism ensures that task running timeout will not affect other tasks; space isolation ensures that illegal addresses operated by tasks will not affect the space of other tasks. [0004] The above two features focus only on isolating the spread of task faults and controlling them within a certain range, and do not deal with the faulty tasks themselv...
