摘要
航空电子系统对飞行控制系统的性能及精度要求越来越高,采用DSP和PCI实现数据的处理和传输成为一种发展趋势,并广泛应用于飞行控制领域。介绍了一种采用F2812及PCI9054实现数据处理和传输的电路,给出了基于F2812及PCI9054的PCI主模式的设计,也给出了一种16位局部数据总线做主模式的解决方案,实现了DSP到PCI的主模式访问,为飞行控制系统提供了高性能的解决方案。
With the development of Avionics system ,the performance and precision of fly control system become more demanding .It is a development trend that DSP and PCI are used to implement data process-ing and transmitting .It has wide application prospects in the field of fly control system T.his paper intro-duces a circuit that use DSP F 2812 and PC9I054 .It gives a design and implementation of PCI master model based on F2812 and PCI 9054 .It provides a way that16-bit data bus takes PCI master model and implements the access of DSP to PCI master model .The circuit provides a high-powered way on data pro-cessing and transmitting of fly control system .
