Embodiment Construction

[0010] The present invention presents a unique communication interface to the peripheral application module, and has a scheduling function, which is somewhat similar to the SHELL (shell) function in the operating system in form, so we define it as a "shell mechanism communication scheduling device".

[0011] like figure 1 As shown, the shell mechanism communication scheduling device 1 of the present invention is used between the operating system 2 and several application modules 3 in the embedded system to complete the scheduling and communication of the upper layer application module 3, and provide the upper layer application module 3 with other peripheral application tasks. The communication interface between modules 4, in our environment, the operating system adopts Vxworks (a popular embedded operating system), and the upper layer application module includes NBAP (Node B application) from WCDMA (Wideband Code Division Multiple Access) Part) The RRC (Radio Resource Control)...

Abstract

The invention is a communication adjusting device based on operation system in embedded system. It realizes the communication among upper models between operation system of embedded system and several application models which are high relation and has no rival, and provides the communication interface for upper application with external application task. The device and the adjusted upper application model are used as a task of the operation system together. The device is made up of adjusting model, information pool model, upper application interface model, operation system interface model, application registered table model.

Description

(1) Technical field [0001] This patent relates to a communication scheduling device based on an operating system in an embedded system. (2) Background technology [0002] In embedded systems, application modules with certain functions are often taken as tasks on the operating system, and the scheduling of application tasks and mutual communication are completed through the operating system. Although such a design can provide high parallelism and real-time performance through pre-preemption between tasks, it performs well in a system with a relatively single function, but when the system is complex, such a design will cause too many tasks on the operating system. Tasks, resulting in an overloaded operating system scheduling burden, low system efficiency, and too many tasks also bring inconvenience to the test, not to mention that not all applications require "pre-preemption". [0003] In order to solve this problem, the general approach is to combine some application module ...
