【摘要】：隨著科技的發(fā)展,FPGA在現(xiàn)實(shí)生活中的應(yīng)用越來越廣泛,但是目前對FPGA器件的重配置普遍都要將FPGA設(shè)備與電腦進(jìn)行連接,再使用廠商提供的配置軟件和配置器件對FPGA進(jìn)行重配置。這種配置方式具有一定的局限性,需要在電腦的周邊進(jìn)行配置,只適用于實(shí)驗(yàn)室環(huán)境和比較平和、穩(wěn)定的生產(chǎn)環(huán)境,當(dāng)需要在非常惡劣且常劇烈變化的環(huán)境下時(shí)(如戰(zhàn)爭情況、野外作業(yè)環(huán)境等),就需要研究一種方便的配置方式。 本設(shè)計(jì)的任務(wù)是運(yùn)用口益發(fā)展的嵌入式技術(shù),使用ARM對FPGA進(jìn)行重配置,使FPGA重配置脫離專用配置軟件,使得FPGA配置時(shí)不需要與電腦進(jìn)行直接連接�？蓪⑴渲梦募A(yù)存在ARM的存儲(chǔ)芯片中,使ARM系統(tǒng)連接到網(wǎng)絡(luò)從遠(yuǎn)程服務(wù)器上下載配置文件來對FPGA進(jìn)行重配置。在后期的設(shè)計(jì)中,對FPGA系統(tǒng)生成的配置文件進(jìn)行處理(格式轉(zhuǎn)換、加密、解密等),并將文件處理的方法推廣到該類型的各個(gè)系列FPGA上去。這樣一來,只要有配置文件就可以對FPGA進(jìn)行配置,而不再需要將FPGA系統(tǒng)和實(shí)驗(yàn)電腦連接在一起。本論文具體完成的內(nèi)容如下： 首先,構(gòu)建了NFS文件系統(tǒng),使得基于ARM的嵌入式Linux系統(tǒng)能夠與遠(yuǎn)程的Linux服務(wù)器進(jìn)行連接,得到相應(yīng)的FPGA配置文件。 其次,設(shè)計(jì)了SPI配置模式下的相關(guān)電路,將ARM與FPGA的配置電路相連接,選用主SPI Flash模式,把ARM設(shè)定為主設(shè)備,FPGA設(shè)定為從設(shè)備,使用ARM對FPGA以SPI重配置的方式對FPGA進(jìn)行重配置進(jìn)行硬件連接。 最后,在Linux系統(tǒng)下,通過ARM將配置文件從服務(wù)器端下載到ARM中,再通過ARM使用SPI通訊協(xié)議將配置文件傳輸?shù)紽PGA中,使FPGA進(jìn)行重配置。這里選用Linux操作系統(tǒng),并在Linux下開發(fā)相應(yīng)的SPI驅(qū)動(dòng)程序。 本論文的設(shè)計(jì)結(jié)果實(shí)現(xiàn)了計(jì)算機(jī)與ARM開發(fā)板之間的NFS文件系統(tǒng)、有線網(wǎng)通信和配置文件的處理,實(shí)現(xiàn)了ARM與FPGA之間的用于進(jìn)行重配置的SPI通信。
[Abstract]:With the development of science and technology, FPGA is more and more widely used in real life. However, the reconfiguration of FPGA devices is generally necessary to connect FPGA devices to computers, and then reconfigure FPGA with configuration software and devices provided by manufacturers. This configuration has certain limitations. It needs to be configured around the computer, only in laboratory environments and more peaceful and stable production environments, when it needs to be in very harsh and often dramatically changing environments (as in war situations). The field work environment and so on, needs to study one kind of convenient configuration way. The task of this design is to use the embedded technology of Kou Yi development to reconfigure the FPGA by using ARM so that the reconfiguration of FPGA is separated from the special configuration software so that the FPGA configuration does not need direct connection with the computer. The configuration file can be pre-stored in the memory chip of ARM, and the ARM system can be connected to the network to download the configuration file from the remote server to reconfigure the FPGA. In the later design, the configuration files generated by FPGA system are processed (format conversion, encryption, decryption, etc.), and the method of file processing is extended to each series of FPGA of this type. As a result, FPGA can be configured as long as a configuration file is available, without the need to connect the FPGA system to the experimental computer. The contents of this thesis are as follows: firstly, the NFS file system is constructed, which enables the embedded Linux system based on ARM to connect with the remote Linux server and obtain the corresponding FPGA configuration file. Secondly, the related circuit in SPI configuration mode is designed, the configuration circuit of ARM and FPGA is connected, the main SPI Flash mode is selected, and the ARM is set as slave device. Use ARM to reconfigure FPGA with SPI reconfiguration. Finally, in Linux system, the configuration file is downloaded from server to ARM through ARM, and then transferred to FPGA through ARM using SPI communication protocol, which makes FPGA reconfigure. Here choose Linux operating system, and develop the corresponding SPI driver under Linux. The design result of this paper realizes the NFS file system between the computer and the ARM development board, the cable network communication and the configuration file processing, and realizes the SPI communication between ARM and FPGA for reconfiguration.
