Design and Implementation of USB1.1 Host and OTG Function Extension

近年来，USB接口技术在消费性电子、通讯等领域得到了越来越广泛的应用。USB的主从架构决定了设备之间必须通过主机才能进行数据交互，而目前扮演主机角色的通常是PC机，这给USB设备之间的数据交互带来了诸多的不便。集成了USB主机功能或USBOTG功能的SoC可以很好的解决这个问题。我们正在合作研发面向金融、税控领域的专用信息处理与控制SoC芯片要求集成USB1.1主机或USBOTG功能。为此本文开发一款USB1.1主机控制器，并在此基础上加入设备控制器和SRP/HNP协议实现，进行OTG功能扩展。从而在金融税控SoC中实现USB1.1主机、设备和全速OTG功能。主要工作成果如下： （1） 设计...In recent years, USB interface has been more and more widely used in the fields of consumer electronics, communication and others. The topology of USB determines that the devices can only make data interact through the Host.

基于FPGA的USB主控芯片软硬件协同设计与验证

设计了一款采用PowerPC架构的USB1.1主机控制器芯片,并对该芯片进行软硬件协同验证。通过内嵌PowerPC和USB主机IP核的FPGA系统,辅以外部收发器电路、驱动、应用程序和文件系统,完成了对U-Disk和HID两类典型USB应用的测试,验证结果表明该USB主机芯片设计可以符合USB技术规范,并能和其他厂家的设备兼容

Ca (NO3) 2 对NaCl 胁迫下木麻黄扦插苗生理特征的调控

用不同浓度Ca (NO 3) 2·4H2O (017、114、211g Ca2+ ök g 土) 对1 年生的处在两种N aCl 胁迫(10 和20gök g) 处理下的木麻 黄扦插苗进行化学调控, 研究硝酸钙盐加氯化钠处理的木麻黄幼苗的生长量、木麻黄幼苗抗氧化酶系统活性和渗透调节物质的 含量的变化, 研究结果表明: 中度N aCl 胁迫加硝酸钙处理下的木麻黄扦插苗的可溶性蛋白质含量增加,MDA 含量降低说明膜 脂过氧化作用减轻, 而且抗氧化酶活性(SOD、POD) 之间协调变化有利于提高清除自由基的速率, 中度盐胁迫下钙盐可以促进 木麻黄体内脯氨酸的积累; 但重度N aCl 胁迫下钙盐对木麻黄的调控作用不显著, 重度盐胁迫下钙盐反而降低木麻黄SOD、 POD 活性和脯氨酸的含量, 减弱了抗氧化酶系统对活性氧的清除作用, 同时高浓度钙盐还会加重N aCl 胁迫对木麻黄幼苗的损 伤, 这说明适量的钙盐有利于木麻黄幼苗抵抗盐胁迫能力的提高, 而高浓度钙盐则可能会加重盐胁迫

Effects of Lanthanum on Redox Systems in Plasma Membranes of Casuarina equisetifolia Seedlings Under Acid Rain Stress

The effects of La3 + on the growth and the ATPases activities of plasma membrane (PM) vesicles isolated from Casuarina equisetifolia seedlings under artificial acid rain (pH 4. 5) stress were studied. The results show that the height , length of roots , fresh weight and PM H+2ATPase activites of Casuarina equisetifolia seedlings increase by the treatments of soaking seeds in LaCl3 solutions with lower concentrations , and those can reach their peak values by treating with 200 mg ·L - 1 La3 + . However , in comparison with the CK, those are inhibited by the higher La3 + concentrations ; PM Ca2 +2AT2 Pase activity is inhibited with the treatments of La3 + . The results also reveal that the H+2ATPase activity and the growth of cell enlarge have a remarkable positive correlation , and La3 + activating H+2ATPase can facilitate plant growth. La3 + al2 so can alleviate cytosolic acidification of plant under acid rain stress and indirectly maintain the stability of intracellular environment . In order to resistant to acid rain and accelerate the growth of Casuarina equisetifolia , the suitable range of La3 + concentrations to soak seeds for 8 h is 50～200 mg·L - 1
