在CCS DSK C5000软件环境下，用C语言描述了自适应滤波器的结构。在TI公司的TMS320C54X系列的TMS320C5402芯片上，完成了基于LMS自适应算法的FIR横向滤波器的设计,并进行了模拟仿真，得出了正确的结果。-Under the circumstance of CCS DSK C5000 software, the adaptive filter is described and designed by C language. Ultimately the design of the LMS algorithm horizontal structural FIR filter is realized using TMS320C5402 device of TMS320C54X family of TI Company, the simulation is done and also the results is correct.
