Problems solved by technology

However, the test results of cyclictest are from the cumulative calculation delay of interrupt response, interrupt service processing time, task preemption time and task scheduling time, and cannot distinguish the above-mentioned stages in detail, especially the response delay, and this response delay It is very important for the R&D personnel positioning stage

Abstract

The invention discloses a hard real-time operating system delay test method and system. The method comprises the following steps: configuring equipment to be tested; configuring a first output port and a first interrupt port on the to-be-tested device; configuring a first test program, a first drive program and a first interrupt processing program in the to-be-tested device; electrically connecting the first output port with the first interrupt port; and initializing the first test program, applying for a memory with a preset length in the to-be-tested device, and initializing the memory to serve as a test result storage area. According to the hard real-time operating system time delay test method and system provided by the invention, the response time delay generated by the system in thewhole response process can be further refined, and when the response time delay index exceeds the standard, developers can be helped to perform accurate and effective positioning.

Description

technical field [0001] The invention belongs to the technical field of hard real-time operating systems, and in particular relates to a delay testing method and system for hard real-time operating systems. Background technique [0002] A real-time system means that the computational correctness of the system depends not only on the logical correctness of the calculation, but also on the time when the result is produced. If the time constraint of the system is not satisfied, the system is considered to be invalid. Therefore, the computer is required to produce the operation result before the specified time limit under the premise that the logical result is correct, otherwise it will have catastrophic consequences. [0003] The standard linux system is not a hard real-time operating system, but the market and the community have introduced several solutions to transform the standard linux system into a hard real-time operating system, namely: (1) preempt rt patch solution; (2) ...
