| This paper is intended to study the development and application of the embedded signalprocessing system based on Matlab/Embedded Coder tool. Combining embedded signalprocessing system development methods, the paper studies the detailed and specifictechniques in the workflow of automatic code generation based on embedded module design.The way that makes full use of Matlab/Simulink model offers an application extensiontechnology, and finally builds a signal system application for an unsupported embedded targetsystem, as well as provides a new technical scheme on developing embedded signalprocessing system.First of all, characteristics of the embedded signal processing system,present development of auto-generation of code, and advantages of using embedded modeldesign methods in system development were summarized. Second of all, detailed realizationtechniques of auto-generation of code in the Matlab/Simulink software platform were studied,including embedded model simulation mechanism, code generation process and codevalidation test. And then, realization process of embedded signal processing algorithm-speechnoise cancellation in TMS320C6713standard board were discussed, established the code andmodule connection, and realized the algorithm module transplantation in choosed board-OMAPL138, completed the executable code generation in different platforms. Finally, thestudy was summarized and the following research was prospected．The techniques studied in the paper made Matlab/Simulink software and DSP embeddeddevelopment platform closely together, provided practical case of embedded signal processingsystem software development design in the Matlab/Simulink software. It has been proved thatthe application of auto-generation of code technique for embedded signal processing systemhas advantages such as speeding up embedded system development, easier to testingverification, reducing costs. Besides, the structure function of system is easy to be expanded,convenient to maintain and upgrade, etc. |
