摘　　要：DSP由于其本身具有并行的硬件乘法器、流水结构以及快速的片内存储器等资源,其技术已广泛地应用于数字信号处理的各个领域.本文以DSP应用系统开发知识为基础,介绍了线性相位FIR数字滤波器的设计方法,并研究了滤波器在TMS320C5402DSP上实现的关键技术.实验证明,借助DSP硬件结构上的优势,所设计的数字滤波器具有运行速度快、能够进行实时信号处理、精度高的优点,其整体性能较优越.DSP has advantaged construction with parallel hardware multiplier, pipeline structure and flash memory, it has been applied in various fields of digital signal processing. On the basis of the DSP application system developing knowledge, the design of linear phase FIR digital filter was introduced. Meanwhile this thesis put an emphase on the realization of filter on TMS320C5402 DSP , which has been approved that the filter can guarantee not only real -time signal processing accurately, but also high speed in virtue of the hardware advantage of DSP. Generally speaking, the filter achieves superiority performance as a whole.
