Implementation method for quickly starting and simultaneously working of slave system when complex time-sharing operating system is started

Abstract

The invention discloses an implementation method for quickly starting and simultaneously working of a slave system when a complex time-sharing operating system is started. The method comprises the following steps that: when the complex time-sharing operating system or a real-time operating system transformed from the complex time-sharing operating system is started, the slave system is initializedand started on another slave processor other than a master processor, and then the slave system and a master system work at the same time at the starting time of the complex time-sharing operating system or in the set starting time period to complete the required task; and the slave system is integrated into the master system at a specific starting time point of the master system, or operates asan independent system in a manner of being compatible with the master operating system all the time, wherein the master processor refers to a master CPU or a master CPU core, and the slave processor refers to a slave CPU or a slave CPU core.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for realizing rapid start-up and simultaneous work of a complex time-sharing operating system when the system is started. Background technique [0002] With the continuous development of people's needs in production and life, the functions of complex time-sharing operating systems are becoming more and more complex, covering more and more aspects, which makes the start-up time of complex time-sharing operating systems longer and longer, such as The startup time of operating systems such as Windows or Android is getting longer and longer, and during this period of system startup time, users cannot do anything other than wait. The extended startup time is acceptable in some fields such as computers and mobile phones. After all, computers and mobile phones do not start frequently. But for many fields or functions, this is unacceptable. For example, in the car field, the dashboard ...

Problems solved by technology

This also prevents the use of complex time-sharing operating systems in these areas or functions

Although there are some flexible solutions, such as the reversing function can be realized through a video switching chip, but they are all temporary solutions, not the root cause. The video switching chip makes the complex time-sharing operating system functions completely unusable

In the existing vehicle-mounted field, none of the complex time-sharing operating systems can quickly start up and run at the same time. Instead, a workaround is adopted, such as running a simple real-time multitasking operating system (RTOS) on another single-chip microcomputer. As a result, the bus, peripherals, functions or ecology of the main operating system or the main system cannot be directly used on this RTOS.
