用可编程DSP器件实现数字滤波,通过修改滤波器参数可方便地改变滤波器的特性。以TMS320F2812数字信号处理器为核心,将滤波器算法作为DSP/BIOS的任务来实现,可方便地实现多任务系统。详细介绍一种基于DSP/BIOS的软件开发过程,并在DSK2812平台上实现数字滤波器的开发实例,对需进行数字信号处理的多任务软件开发具有一定的参考价值。
Abstract:
 Through the programmable DSP chip realizes digital filter.The features of filter can be convenient changed through modifying its parameters.In this paper,the system uses TMS320F2812as the core,the realization of filter algo-rithm is treated as a task of DSP/BIOS,the multitask syetem can be easily realized.A software development process based on DSP/BIOS is also introduced,and the example of implementing the digital FIR filter in the DSK2812platform is given.This paper has a certain reference value to the multitask software development which needs digital signal processing
