[0027] 2. The operating system of the slave core cannot be restarted separately, only the operating systems of the master core and the slave core can be restarted at the same time
[0028] Since the Boot loader runs on the main core, if the main core is not restarted, the operating system of the slave core cannot be restarted
[0029] In summary, the existing methods for starting multiple operating systems are not flexible enough and inconvenient to use

Embodiment Construction

[0048] The core idea of ​​the present invention is: each operating system in the multi-operating system corresponds to a Boot loader, and each Boot loader shares hardware resources with the corresponding operating system; since the address of the first instruction executed after each core is powered on are the same, so each Boot loader needs to share a small amount of common code. After each core determines the number of the operating system to be started, it enters the corresponding Boot loader code for execution to start the corresponding operating system.

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

Abstract

The invention discloses a method for starting a multioperation system and a device thereof. The method comprises: configuring a separate starting loading program for each operation system in the multioperation system, and the correspondent operation system is respectively started by starting the loading program. The technical proposal of the invention leads the starting of the multioperation system to be more flexible, thus being convenient for use.

Description

technical field [0001] The invention relates to the technical field of multiple operating systems, in particular to a method and device for starting multiple operating systems. Background technique [0002] A multi-core processor consists of multiple cores, including a master core and several slave cores. The master core is the first core started after the multi-core processor is powered on; the slave core is the core enabled by the master core after the master core is started. Generally, when the hardware of the slave core is restarted, the hardware of the main core will not be restarted; but when the hardware of the main core is restarted, the entire multi-core processor will be restarted. Therefore, the operating system running on the master core is called the master operating system, and the operating system running on the slave core is called the slave operating system. [0003] figure 1 It is a schematic diagram of a typical hardware architecture of a multi-core pro...
