Method and device for controlling multiple operating systems, electronic equipment and computer storage medium

Abstract

An embodiment of the present invention provides a method and device for controlling multiple operating systems, electronic equipment and a computer storage medium. The method is applied to a multi-core processor, a first part core unit of the processor is used for running a time-sharing operating system, and a second part core unit of the processor is used for running a real-time operating system.The method includes a step of acquiring an interrupt request requiring a response, a step of querying a mapping relationship between the interrupt request and an operating system type and determiningthe operating system type mapped by the interrupt request requiring the response, a step of sending the interrupt request requiring the response to the first part core unit if the operating system type corresponding to the interrupt request requiring the response is the time-sharing operating system, and a step of sending the interrupt request requiring the response to the second part core unit if the operating system type corresponding to the interrupt request requiring the response is the real-time operating system. Thus, an effect of simultaneously processing a complex task and a real-timetask in one processor is achieved in the embodiment of the present invention.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a multi-operating system control method, device, electronic equipment and computer storage medium. Background technique [0002] Generally, operating systems include real-time operating systems and time-sharing operating systems. Among them, the real-time operating system is used to realize real-time tasks. Real-time tasks are tasks that can respond within a predictable time. A time-sharing operating system is used to implement time-sharing tasks. Time-sharing tasks refer to tasks that need to mobilize a large number of computing resources to calculate results, but do not require timeliness. Wherein, a task may also be called an event. When there is a task to be processed, the interrupt source sends an interrupt request corresponding to the task to be processed to the processor. Specifically, when a real-time task needs to be processed, the interrupt source sends...

Problems solved by technology

[0004] Therefore, in existing applications that can handle both real-time tasks and time-sharing tasks, it is necessary to use a processor running a real-time operating system and a processor running a time-sharing operating system to perform real-time tasks and time-sharing tasks respectively. tasks, resulting in higher processor usage costs
