数字信号处理器与仿真软件接口设计

Design of digital signal processor and simulation software’s interface

文中针对DSP与计算机软硬件接口能力差,无法将其丰富的资源为开发者所利用的现象,提出基于MATLAB设计和DSP汇编语言编写FIR滤波器的方案。介绍利用MATLAB从文件中获得数据,通过接口函数传给DSP进行运算处理的过程。实践证明,这种方案准确度高、稳定性好,易于移植,具有较强的实用性与灵活性。

The ability of DSP to connect computer＇ s software and hardware is limited, so it is unable to utilize by developers well. In this paper, we present a scheme of FIR filter, which is designed by MATLAB and programmed by assemble language in DSP. We use MATLAB to acquire the data from files, and pass it to DSP for some operation. It is proved that this scheme is practical and feasible, with high accuracy, good stability and portability
