摘要
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。
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 TMS320F2812 as 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 DSK2812 platform is given. This paper has a certain reference value to the muhitask software development which needs digital signal processing.
