摘　　要：在介绍在系统可编程模拟器件ispPAC 30结构与特性的基础上,通过微机、微控制器或数字信号处理器对ispPAC 30进行实时动态重构。同时利用SP I进行实时配置,通过对ispPAC 30写入不同的配置数据,动态改变ispPAC 30的内部电路结构,实现了增益和截止频率都可调的低通滤波器设计。实验表明ispPAC 30可以实现实时的动态编程控制,在模拟电路设计上有很好的灵活性和实用性。The performance of the in-system programmable device ispPAC30 is introduced. The way for using μControl, processor or DSP is used to control and configure the ispPAC30 dynamically. The internal circuit of the ispPAC30 can be changed by configuring the different data. The ispPAC30 can be configured as the lowpass filter, the gain and the cut-off frequency can be dynamically changed. The experiment indicates that the ispPAC30 can be used by realtime programming, and brings great flexibility and usability in the design of the analog circuit.
