Problems solved by technology

This processing method has the following deficiencies: (1) When the equipment implanted in the SPARC platform is an unmanned operating equipment, it needs effective remote plus power-off means to manually assist in completing the exception handling, which lacks autonomy; (2) Complete the system reset The time delay of power-on and power-off operations is large, and the failure to handle exceptions in time will affect the continuity of system operation; (3) After the system is powered on again, some runtime environment information may be lost, which is not conducive to the subsequent positioning of exceptions and repair; (4) The operation of re-powering off the system will often cause system business interruption. For some key systems, business interruption is not allowed

Abstract

The present invention relates to a SPARC platform-oriented embedded software exception autonomous processing method and device, wherein the method includes: determining the current partition where the target software runs; judging whether the current partition is the partition where the underlying public function runs; determining the backup Select the state transition linked list; according to the running state partition table, judge whether the running partition corresponding to the alternative state transition linked list includes the current partition, and the jump indicated by the jump condition field corresponding to the alternative state transition linked list conditions can be met. The embedded software exception autonomous processing method and device oriented to the SPARC platform provided by the embodiment of the present invention realizes the autonomous processing of the exception, and the time delay is small; avoids the occurrence of system service interruption; and saves the register group and the stack at the same time Runtime information such as content is also conducive to the analysis and positioning of subsequent abnormal problems.

Description

technical field [0001] The invention relates to the field of embedded software, in particular to a SPARC platform-oriented embedded software exception autonomous processing method and device. Background technique [0002] SPARC is the current mainstream processor architecture, and embedded software for the SPARC platform may experience abnormalities during operation, resulting in system resets or even continuous resets. Once this situation is not handled properly or not in time, critical systems with high safety requirements such as aerospace and automotive electronics may lead to system failure or serious losses. [0003] At present, the method for abnormal processing of continuous reset of embedded software oriented to the SPARC platform is mainly manual operation to re-power on or switch to a backup device for re-running. This processing method has the following deficiencies: (1) When the equipment implanted in the SPARC platform is an unmanned operating equipment, it ne...
