【摘要】：USB如今已成為一種PC機(jī)和外設(shè)之間常用的交換數(shù)據(jù)的接口,各式各樣的便攜式外設(shè)都使用USB接口進(jìn)行通信。所以希望數(shù)碼便攜產(chǎn)品之間能夠直接進(jìn)行數(shù)據(jù)的交換,從而擺脫目前對PC機(jī)的依賴的情況。在這種需求下,USB IF推出的OTG(On-The-Go)規(guī)范應(yīng)運而生,此規(guī)范能夠?qū)崿F(xiàn)兩個不同的外設(shè)之間通過USB接口直接傳輸數(shù)據(jù)。 ISP1362芯片是飛利浦公司的OTG產(chǎn)品,在芯片上集成了一個OTG控制器、一個高級主控制器和一個外設(shè)控制器。ISP1362的OTG控制器能夠完全兼容USB2.0及OTG Supplement1.0協(xié)議,主機(jī)和設(shè)備控制器能夠兼容USB2.0協(xié)議,支持12MB/s的高速傳輸和1.5MB/s的低速傳輸。因此本文設(shè)計了一個能夠應(yīng)用在SOPC系統(tǒng)中的以ISP1362芯片為基礎(chǔ)的ISP1362Host IP及驅(qū)動,此系統(tǒng)的設(shè)計可以完成SOPC的CPU與ISP1362芯片的通信。 固件選用方面,本系統(tǒng)選擇Altera公司的DE2-70開發(fā)板上的Cyclone Ⅱ2C70FPGA芯片作為CPU,利用飛利浦公司的ISP1362作為USB接口芯片,構(gòu)成了USB主控制設(shè)備；以USB光電鼠標(biāo)和VGA顯示器為從設(shè)備,完成了系統(tǒng)功能的展示和測試。 程序編寫方面,基于ISP1362芯片及OTG協(xié)議,在Quartus Ⅱ和Nios Ⅱ平臺上編寫程序?qū)崿F(xiàn),所編寫程序通過JTAG接口協(xié)議下載到SOPC開發(fā)板的SDRAM單元中,使硬件系統(tǒng)按所預(yù)期目標(biāo)執(zhí)行工作。 完成的軟件工作有：ISP1362控制器的設(shè)備配置編程,Nios Ⅱ中ISP1362驅(qū)動的編寫,VGA控制器的設(shè)備配置編程。 經(jīng)測試證明,本系統(tǒng)完成了基于ISP1362芯片接口IP核及驅(qū)動的設(shè)計方案,能很好的實現(xiàn)CPU與ISP1362芯片的通信。
[Abstract]:USB has become a common interface between PC and peripherals to exchange data. A variety of portable peripherals use USB interfaces for communication, so it is hoped that digital portable products can directly exchange data. In order to get rid of the current dependence on PC, the OTG On-The-Go-specification developed by USB if came into being. This specification enables two different peripherals to transmit data directly through the USB interface. The ISP1362 chip is a Philips OTG product that integrates a OTG controller on the chip. The OTG controller of an advanced master controller and a peripheral controller. ISP1362 can be fully compatible with the USB2.0 and OTG Supplement1.0 protocols. The host and device controllers are compatible with the USB2.0 protocol. It supports high speed transmission of 12 MBs and low speed transmission of 1.5MB / s. Therefore, a ISP1362 based on ISP1362 chip which can be used in SOPC system is designed in this paper. Host. IP and driver. The design of this system can complete the communication between SOPC CPU and ISP1362 chip. In the aspect of firmware selection, this system chooses Cyclone 鈪，
