Linux在Xilinx FPGA上的移植

Transplantation of Linux OS on Xilinx FPGA

Xilinx公司开发的Virtex-Ⅱ pro等FPGA结合可编程片上系统(SOPC)技术嵌入了PowerPC处理器硬核。本文结合Linux操作系统的优点及PowerPC嵌入式处理器硬核,在Virtex-Ⅱ Pro开发平台上,研究并实现了Linux操作系统在PowerPC405处理器中的移植,其中包括硬件平台的定制、交叉编译环境的建立、内核的配置及根文件系统的制作,最后通过具体的应用验证了系统的稳定性及可靠性。文中将处理器、操作系统与FPGA融合在一起完成既定的信号处理任务,既具有操作系统多任务、实时性等优点,又充分发挥了FPGA的优势,具有较好的应用前景。

The FPGA such as Virtex-II pro developed by Xilinx Company is embedded with Power PC processor hard core by combining technology of programmable system on chip （SOPC）. Integrating the advantages of Linux operating system （OS） and the embedded PowerPC processor hard core, the transplantation of Linux OS in the PowerPC405 processor on the Virtex-II Pro developing platform is studied and implemented, among which the customization of hardware board, establishment of cross compiler, configuration of Linux kernel and the construction of a root file system are included. At the end, the stability and reliability of the system are verified by concrete application. The processor, OS and FPGA are fused to complete the established signal processing task. It is featured as not only multitask and real time, but also the advantages of FPGA is executed. It has perfect application prospect.
