TMS32010自适应均衡系统的开发与实现

本文使用新一代的高速信号处理片TMS32010设计出LMS算法的自适应均衡(AE)系统。在收敛性能、处理速度、小型化、使用灵活性及成本费用诸方面均优于或等于用模拟电路、专用数字电路及一般16位微机制成的AE系统。文中叙述了TMS32010 AE系统的设计思想,总体设计和硬、软件设计方法,结构框图,设计时需注意的各种问题以及试验結果。通过实验证明,系统是成功的,其性能与理论分析相符。本文所述方法除可用于LMS算法的AE设计外,也可用于其它AE算法的设计,且若适当改变程序及少量输出接口硬件,尚可用于其它数字信号处理,如调制解调、谱估计及声音控制等。

DEVELOPMENT AND IMPLEMENTATION OF ADAPTIVE EQUALIZATION SYSTEM BY TMS32010 CHIP

An adaptive equalization system (AE) with LMS algorithm is designed using TMS32010 chip,which is a new generation of digital signal processor.In the respects of convergence performance, rapidness processing, simplicty on structure, flexibility in adjustment,lightness and cost, it is better than or equals to that made by analog circuits,special digital circuits or common digital computer (16 bits). The basic thought in design, methods of total design,hardware and software design, structure block diagram, the problems which should be noted and the testing results are disscussed. These resultscoincide with theoretical analysis, and it is seen that this design is successful.A method discussed in this paper may be also used to design of systems with other AE algorithm and other kinds of digital sigal processing, such as modem, spectral analysis and speech control, when programs and a few interfaces are altered.
