【摘要】：隨著嵌入式技術的快速發(fā)展，人們對嵌入式系統(tǒng)的性能要求越來越高，在這種高性能的要求下，基于PowerPC和VxWorks的嵌入式板卡系統(tǒng)是近年來嵌入式系統(tǒng)研究的重點之一。高性能、低功耗的PowerPC和高穩(wěn)定性、高實時性的VxWorks越來越多的出現(xiàn)在各種嵌入式產品中，其中包括軍工產品、航空航天設備等等。 本文是以基于PowerPC處理器為硬件架構平臺來開發(fā)U-Boot、VxWorks BSP，并將U-Boot、VxWorks成功移植到該平臺上還可以進行信號處理驗證等。本文在分析了嵌入式目標板的硬件需求之后首先設計構造了基于該目標板的固件引導程序U-Boot，實現(xiàn)了對CPU和板載其他硬件設備的初始化，如PCI設備、RapidIO交換機、North Flash等等，并且對硬件設備進行了自檢設計以確保VxWorks系統(tǒng)能夠成功啟動。其次主要對VxWorks BSP中的串行設備驅動和網絡設備驅動進行了進一步開發(fā)，包括：實現(xiàn)了串行設備驅動成功運行并且在串口有輸出；完成了在目標板上與PC機上可以相互PING通，以保證網絡的暢通。之后在上述的基礎平臺上開發(fā)了FFT運算性能的測試函數，該函數可以實現(xiàn)對多個點數FFT運算時間的驗證，并且對該代碼進行了詳細測試，同時也分析了FFT運算測試的過程和結論。最后從整體上驗證了該嵌入式系統(tǒng)的穩(wěn)定性和可靠性，達到了該嵌入式系統(tǒng)研究的最終目的。
[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 .
