Customized dual system

Abstract

The invention discloses a customized dual system and particularly relates to the technical field of system operation. The invention a comprises customized dual system. The system comprises a vxWorks system and a linux system, wherein the vxWorks system and the linux system are respectively installed on the multi-core processor, the vxWorks system and the linux system are independently operated anddistributed, the connection end of the multi-core processor is provided with hardware resources, and the hardware resources comprise a CPU core, a memory, an interrupt manager and an external device.The method comprises the following steps of: setting two independently running operating systems vxWorks system and linux system on a multi-core processor; according to the vxWorks + linux dual system, VxWorks can be used for managing relatively emergency tasks, and VxWorks can also be used for managing relatively emergency tasks; the vxWorks system and the linux system share the memory through the interaction space to realize data interaction, so that the operation stability of the system is improved, the operation efficiency is high, and blockage is avoided.

Description

technical field [0001] The invention relates to the technical field of system operation, and more specifically, the invention relates to a customized dual system. Background technique [0002] The traditional dual system is realized through Xen. Xen is an open source project developed by the computer laboratory of Cambridge University. It is a software layer that runs directly on the computer hardware to replace the operating system. It can run concurrently on the computer hardware. Run multiple guest operating systems (Guest OS), but Xen has the following disadvantages: [0003] 1) Xen will occupy a relatively large space; [0004] 2) Any operation with a high I / O rate or any operation that eats up resources will bog down Xen; [0005] 3) It has a certain impact on the real-time performance of the vxWorks system. [0006] The customized dual system is implemented by directly running the dual system on the bare core without conversion of the intermediate layer. In this wa...

Problems solved by technology

[0003] 1) Xen will occupy a relatively large space;

[0004] 2) Any operation with a high I / O rate or any operation that eats up resources will bog down Xen;

[0005] 3) It has a certain impact on the real-time performance of the vxWorks system

[0006] The customized dual system is implemented by directly running the dual system on the bare core without conversion of the intermediate layer. In this way, the functions of each system in the dual system are basically the same as those running in a single system mode, which solves the shortcomings of Xen. Existing custom dual systems require special system customization for different multi-core processing platforms, such as ARM and POWERPC
