The invention relates to a real-time dynamic scheduling policy test method based on digital microkernel. The method schedules the system on the basis of the scheduling policy of the microkernel; the essence of the digital microkernel dynamic scheduling is to realize task scheduling accuracy and task scheduling real-time performance according to complicated task demands, so as to satisfy the system requirements for accurate time and actuating logic; the invention abstracts the digital microkernel and logic application into a dynamic real-time object, establishes a unified model by using the system resources and application resources, dynamically tracks the real-time logic behavior of the resources in the relative time track record model according to the behavior of the model, and tests thereal-time performance and accuracy of the system operation by analyzing a real-time logic behavior time sequence report.
Description
technical field [0001] The invention relates to a real-time dynamic scheduling strategy testing method based on a digital microkernel, and belongs to the technical field of embedded real-time operating system microkernels. Background technique [0002] Embedded real-time operating system microkernel technology is a key technology widely used by smart devices in the field of smart substation automation, and its kernel real-time dynamic scheduling strategy is the core technology. The kernel real-time dynamic scheduling strategy directly affects the reliability of smart devices, real-time performance and scalability. The kernel's real-time dynamic scheduling strategy manages the software and hardware of smart devices as a whole, and through system application requirements, schedules and allocates all resources owned by the kernel system, and implements the external and internal behavior of the system. At present, the application based on the digital microkernel is extremely co...
