Embodiment 1

[0020] Please refer to figure 1 , the embodiment of the present invention provides a kind of cold fire real-time processing method based on Linux platform, comprising:

[0021] 101. Assign low priority to the Linux kernel in advance, assign high priority to real-time tasks, and prohibit the Linux kernel from shielding high priority interrupts.

[0022] The technical solution provided by the embodiment of the present invention is based on the Linux platform, utilizes the feature that CPU interrupts can be controlled by priority, and adopts the application mode of "real-time interrupt + kernel process". Specifically, assign different priorities to the Linux kernel and the processes or programs running in it, including: assigning low priorities to the Linux kernel and non-real-time task processes that continue to run in the Linux kernel, and assigning high priorities to real-time tasks . In this way, the non-real-time process and the real-time process can be controlled differen...

Embodiment 2

[0033] Please refer to figure 2 and image 3 , the embodiment of the present invention provides a kind of cold fire real-time processing method based on Linux platform, comprising:

[0034] The preset unit 201 is used to assign low priority to the Linux kernel in advance, assign high priority to real-time tasks, and prohibit the Linux kernel from shielding high priority interrupts;

Abstract

The invention discloses a method for real-time cold fire processing based on a Linux platform. The method includes that low priority is assigned to a Linux inner core in advance, high priority is assigned to a real-time task, and the Linux inner core is prevented from screening and the high priority is prevented from interruption; when interrupt conditions of the high priority appear, non-real-time task process of the low priority running in the Linux inner core is interrupted by the aid of a real-time communication layer; according to request content of interruption of the real-time communication layer, real-time task process of the corresponding high priority is carried out; and after the operation of the real-time task process of the high priority ends, the non-real-time task process of the low priority is reset. An embodiment of the invention further provides a corresponding system. The technical scheme solves the problem of low real-time property of existing Linux platforms, and has the advantages of high real-time property, high reliability, low development and transplanting difficulty of related applications and the like.

Description

technical field [0001] The invention relates to the technical field of computer processing, in particular to a method and system for real-time cold fire processing based on a Linux platform. Background technique [0002] The Linux system has the advantages of free, open source code, stable and reliable kernel, support for many CPU architectures, and powerful network communication functions, so it is widely used in embedded systems. But in embedded systems, Linux also has a fatal flaw, that is, the real-time performance is not strong. In the power transformation and distribution system of the power industry, especially among the various functions of the distribution network monitoring terminal, the data sampling and fault discrimination functions have high requirements for real-time performance, which leads to the fact that the existing Linux cannot fully meet the needs. Contents of the invention [0003] Embodiments of the present invention provide a method and system for...
