Abstract: Provided in the embodiments of the present disclosure are a method and apparatus for controlling running of an operating system, and an embedded system and a chip. The embedded system includes a chip and at least two operating systems. The chip includes a processor, a hardware controller, a first bus, and a second bus. The bandwidth of the first bus is higher than the bandwidth of the second bus; the first bus is configured as a multi-master and multi-slave mode; and the second bus is configured as a one-master and multi-slave mode. The at least two operating systems are configured to run on the basis of the processor; the at least two operating systems are configured to communicate with each other by the first bus; and the at least two operating systems are configured to control the hardware controller by the second bus.

Abstract: An embedded system running method includes: allocating, according to a resource dynamic allocation rule, a group of services to be allocated to corresponding operating systems in an embedded system, wherein the embedded system includes a first operating system and a second operating system, and a response speed of the first operating system is higher than a response speed of the second operating system; determining resource allocation results corresponding to the group of services to be allocated, where the resource allocation results are used for indicating, among processing resources of the processor, a processing resource corresponding to each of the group of services to be allocated; and allocating the processing resources of a processor to the first operating system and the second operating system according to an operating system allocation result and the resource allocation result corresponding to each of the group of services to be allocated.
