可编程逻辑 XAPP708 -133MHz PCI-X到128MB DDR小型DIMM存储器桥
 
The Virtex-4 features, such as the programmable IDELAY and built-in FIFO support, simplifythe bridging of a high-speed, PCI-X core to large amounts of DDR-SDRAM memory. Onechallenge is meeting the PCI-X target initial latency specification. PCI-X Protocol Addendum tothe PCI Local Bus Spec ...
可编程逻辑 通信的数学理论
The fundamental problem of communication is that of reproducing at one point either exactly or approximately a message selected at another point. Frequently the messages have meaning; that is they refer to or are correlated according to some system with certain physical or conceptual entities.

可编程逻辑 Virtex-5 GTP Transceiver Wizar
The LogiCORE™ GTP Wizard automates the task of creating HDL wrappers to configure the high-speed serial GTP transceivers in Virtex™-5 LXT and SXT devices. The menu-driven interface allows one or more GTP transceivers to be configured using pre-definedtemplates for popular industry standa ...
测试测量 LT5528 WCDMA ACPR和AltCPR测量
 
ACPR (adjacent channel power ratio), AltCPR (alternatechannel power ratio), and noise are important performancemetrics for digital communication systems thatuse, for example, WCDMA (wideband code division multipleaccess) modulation. ACPR and AltCPR are bothmeasures of spectral regrowth. T ...
测试测量 BGP测试工具集的设计与实现
协议是互联网络的灵魂，而协议测试是确保网络交互畅通无阻的守护神。尤其是当人们进入一个新的纪元，网络通信成为信息流通的首选手段，与协议不符合的产品必将被淘汰，因而协议测试也越来越受到人们的重视。Protocols are the soul of the Internet, and Protocol Testing isa guarding deamon for the network transaction ...
接口技术 USB调试与开发
现在，您可在新的MCU项目中加入供连接多个器件和外设的USB接口，这比过去惯用的SPI和UART看起来要复杂些。参加本会议可以了解如何使用Beagle Protocol Analyzer实施、分析和调试飞思卡尔MCU的USB系统。
