基于FPGA的可重新配置片上导航计算机设计

采用Virtex-4 FPGA芯片设计了片上组合导航计算机系统.该导航计算机使用FPGA内嵌的PowerPC硬核处理器进行导航运算,在FPGA逻辑中集成IP核来实现控制、接口通信和部分运算的硬件加速,提高了系统集成度.此外,该系统还可以通过硬件编程对FPGA逻辑进行重新配置,使该导航计算机在不同应用场合满足对接口、功能的要求.

Design of Re-Configurable On-Chip Navigation Computer Based on FPGA

The combinational navigation computer system on the chip is designed by using Virtex-4 FPGA. Using FPGA embedded PowerPC hard core processor, this navigation computer carrys out the navigation operation. Using the integral IP core in the FPGA logic, the control, the bardware acceleration of the interface communication and the part operation are realized. The integral degree of the system is enhanced. Furthermore, this system can be re-configurated. And then on different situations it makes the navigation system meets the requirement for the interface and function.
