【摘要】：隨著嵌入式技術(shù)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(chǎn)品中，其中包括軍工產(chǎn)品、航空航天設(shè)備等等。 本文是以基于PowerPC處理器為硬件架構(gòu)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(jìn)行信號處理驗證等。本文在分析了嵌入式目標(biāo)板的硬件需求之后首先設(shè)計構(gòu)造了基于該目標(biāo)板的固件引導(dǎo)程序U-Boot，實現(xiàn)了對CPU和板載其他硬件設(shè)備的初始化，如PCI設(shè)備、RapidIO交換機(jī)、North Flash等等，并且對硬件設(shè)備進(jìn)行了自檢設(shè)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(shè)備驅(qū)動和網(wǎng)絡(luò)設(shè)備驅(qū)動進(jìn)行了進(jìn)一步開發(fā)，包括：實現(xiàn)了串行設(shè)備驅(qū)動成功運行并且在串口有輸出；完成了在目標(biāo)板上與PC機(jī)上可以相互PING通，以保證網(wǎng)絡(luò)的暢通。之后在上述的基礎(chǔ)平臺上開發(fā)了FFT運算性能的測試函數(shù)，該函數(shù)可以實現(xiàn)對多個點數(shù)FFT運算時間的驗證，并且對該代碼進(jìn)行了詳細(xì)測試，同時也分析了FFT運算測試的過程和結(jié)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(dá)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 .
