Embodiment Construction

[0023] refer to figure 1 . figure 1 What is described is the workflow of realizing the software communication architecture on the embedded platform.

[0024] In step 1, use CE software to model the software and hardware of the system; firstly, according to the data processing process of the waveform, divide the entire waveform into several functional modules, analyze the data transmission process between each module, and determine the connection relationship and data Processing type and mode, abstracting functional module objects into component models, using IDL to define communication interfaces between components, abstracting the collection of several component models with specific connection relations into application models; the present invention relates to two platforms of PowerPC and DSP, and uses Both PowerPC and DSP processors are abstracted into executable device models. According to the hardware conditions required by the waveform data processing process, a set of s...

Abstract

The invention provides a method of realizing a software communications architecture (SCA) on an embedded platform, comprising the following steps of: by using a CORBA (Common Object Request Broker Architecture) middleware as a software bus and using an XML (Extensible Markup Language) document as an information middleware, constructing framework software on the embedded platform of a Power PC (Personal Computer) and a DSP (Digital Signal Processor); by using a component engine (CE) to assist a tool developed by the SCA, carrying out software modeling and hardware modeling on the system; encoding IDL (Interface Define Language) codes of a core framework by using a CORBA encoder to generate a pile document and a framework document, of an interface for realizing a servo class of the framework interface; generating an XML domain description document for an application model and a platform model of the system by using the CE software; improving and extending a CE code generator, compiling a code template of a device and a component program framework to realize a component program and a device program; and running the component program and the device program on different nodes to test the correctness of a waveform function. Therefore, the communication system software developed by using the architecture provided by the invention has interoperability, reconfigurability, updatability, reusability and transportability.

Description

technical field [0001] The present invention relates to a method for realizing software communication architecture (SCA) on an embedded platform, and relates to description and analysis of SCA norms, component-based software development, object request agent architecture (CORBA) middleware, and extensible description language (XML) And software development technology under embedded system. (Embedded system refers to a special-purpose computer system that is completely embedded in the controlled device and designed for specific applications, such as "power" chip (PowerPC) and digital signal processor (DSP) all belong to the embedded category). Background technique [0002] Traditional communication systems are often designed according to specific purposes and have relatively single functions, which do not have reconfigurability. Some communication systems have similar basic structure, but the signal characteristics are very different, for example, the working frequency band ...
