Problems solved by technology

For existing operating systems, because these operating systems usually exist in the main memory of the system, their interrupts can be implemented through hardware or software programming, but in the embedded SRAM operating system, since the operating system kernel runs on the SRAM on the CPU chip Among them, the interrupt method cannot be simply realized by the common existing interrupt method, for example, for the implementation of SRAM management, the interrupt requested by the SRAM operating system, etc., the implementation method cannot be satisfied by the existing program interrupt method, so a New Method to Realize Interrupts of Embedded SRAM Operating System

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] A kind of implementation method of embedded SRAM operating system interruption, appended figure 1 It is an overall schematic diagram of the implementation process of the present invention, and its specific implementation method is as follows:

[0034] 1) Define the embedded SRAM operating system interrupt

[0035] In the embedded SRAM operating system, the definition of interrupt is as follows, such as figure 2 :

[0036] ·Software interrupt is an interrupt caused by the execution of a certain instruction during the running of the program. For example, overflow, division by zero, illegal machine instructions, etc.

[0037] · Timing interrupt, generated by the internal timer of the processor. Timing interrupts are not only the basis of computer timing, but also the prerequisite for the operating system to complete many complex operations, such as alternate ...

Abstract

The invention relates to a method for providing an interrupt signal to embedded SRAM operating system. The method comprises defining embedded SRAM operating system interrupt signal, identifying priority level of the interrupt signal and processing the interrupt signal. The method has the advantages of having real-time and high efficiency, and having rapid response rate.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a method for realizing interruption of an embedded SRAM operating system. Background technique [0002] Interruption refers to the process of suspending the running of the current program on the CPU when an event occurs during program execution and leading to the execution of the program that handles the event. Modern computer systems generally have the ability to deal with emergencies. For example: read a set of information from the magnetic tape, and when it is found that there is an error in the read-in information, as long as the tape is returned to reread the set of information, the error may be overcome and the correct information obtained. [0003] This ability to deal with emergencies is accomplished by hardware and software collaboration. First, the interrupt device of the hardware finds the generated event, then, the interrupt device stops the execution of th...
