【摘要】：随着嵌入式技术的快速发展，人们对嵌入式系统的性能要求越来越高，在这种高性能的要求下，基于PowerPC和VxWorks的嵌入式板卡系统是近年来嵌入式系统研究的重点之一。高性能、低功耗的PowerPC和高稳定性、高实时性的VxWorks越来越多的出现在各种嵌入式产品中，其中包括军工产品、航空航天设备等等。本文是以基于PowerPC处理器为硬件架构平台来开发U-Boot、VxWorks BSP，并将U-Boot、VxWorks成功移植到该平台上还可以进行信号处理验证等。本文在分析了嵌入式目标板的硬件需求之后首先设计构造了基于该目标板的固件引导程序U-Boot，实现了对CPU和板载其他硬件设备的初始化，如PCI设备、RapidIO交换机、North Flash等等，并且对硬件设备进行了自检设计以确保VxWorks系统能够成功启动。其次主要对VxWorks BSP中的串行设备驱动和网络设备驱动进行了进一步开发，包括：实现了串行设备驱动成功运行并且在串口有输出；完成了在目标板上与PC机上可以相互PING通，以保证网络的畅通。之后在上述的基础平台上开发了FFT运算性能的测试函数，该函数可以实现对多个点数FFT运算时间的验证，并且对该代码进行了详细测试，同时也分析了FFT运算测试的过程和结论。最后从整体上验证了该嵌入式系统的稳定性和可靠性，达到了该嵌入式系统研究的最终目的。
[Abstract]:With the rapid development of embedded technology , the performance requirement of embedded system is more and more high . Under the requirement of high performance , the embedded board card system is one of the emphases of the research of embedded system in recent years . VxWorks with high performance , low power consumption , high stability and high real - time performance appears in all kinds of embedded products , including military products , aerospace equipment and so on .

This paper develops the U - Boot and VxWorks BSP based on the hardware architecture platform based on the PC processor . After analyzing the hardware requirements of the embedded target board , this paper first designs the firmware bootstrap U - Boot based on the target board , and realizes the initialization of CPU and other hardware devices , such as PCI equipment , Rapid IO switch , North Flash , etc . The hardware equipment is designed to ensure that the VxWorks system can be started successfully . Secondly , the serial device driver and network equipment drive in VxWorks BSP are further developed , including :
After completing the test function of FFT operation performance on the base platform , this function can realize the verification of the FFT operation time of multiple points , and also analyze the process and conclusion of FFT operation test . At last , the stability and reliability of the embedded system are verified from the whole , and the final purpose of the embedded system research is achieved .
