Problems solved by technology

Since the functions of the real-time core include processing real-time interrupts, passing non-real-time interrupts to non-real-time cores, and providing virtual interfaces for hardware operations and interrupt processing to non-real-time cores, this greatly improves the design time of the real-time system, and the design Personnel leaves need to make a lot of modifications to the underlying code of the non-real-time kernel (usually an ordinary operating system), which is not conducive to development and transplantation
At the same time, the unified storage space makes the operation of non-real-time tasks have a certain impact on the operation of real-time tasks, such as swapping in and out of memory, and system reliability is also reduced

Embodiment Construction

[0033] In conjunction with the drawings, the present invention is further described through specific embodiments.

[0034] A method for realizing multi-operating system cooperative work, comprising the following steps:

[0035] (1) Start the general operating system:

[0036] Start the general-purpose operating system, load the real-time system into the built-in SRAM of the processor, and the general-purpose operating system continues to run and waits for the arrival of the real-time interrupt;

[0037] (2) Receive real-time interrupt:

[0038] The general-purpose operating system responds to real-time interrupts arriving at any time, receives real-time interrupts and enters the real-time interrupt processing function, and saves the real-time interrupt context;

[0039] (3) Save key runtime information of the general-purpose operating system:

[0040] First, replace the real-time interrupt processing function of the current general operating system with the new real-time in...

Abstract

A method for realizing coordination operation of multi-operation system includes starting up universal operation system and loading real time system, receiving real time interruption, holding key information in operation of universal operation system, executing real time system and finalizing operation of real time task, entering the second interruption to prepare to disengage real time system, revising return-back system, disengaging interruption to return back to universal operation system and disengaging real time interruption of universal operation system.

Description

technical field [0001] The present invention relates to the field of embedded operating systems, and more specifically, relates to a method for realizing cooperative work of multiple operating systems. Background technique [0002] With the development of computer technology and people's pursuit of efficiency, the operating system has changed from single task to multi-task, and from multi-task to multi-thread parallelism. Today, in addition to continuously improving the parallelism of programs on a single operating system, more and more working environments also require multiple operating systems to run simultaneously. [0003] The emergence of virtualization technology meets this requirement. It allows one platform to run multiple operating systems at the same time, and the application programs can run in independent spaces without affecting each other, thus significantly improving the work efficiency of the computer, and at the same time providing great convenience for pr...
