PCI Express是由Intel,Dell,Compaq,IBM,Microsoft等PCI SIG联合成立的Arapahoe Work Group共同草拟并推举成取代PCI总线标准的下一代标准。PCI Express利用串行的连接特点能轻松将数据传输速度提到一个很高的频率,达到远远超出PCI总线的传输速率。一个PCI Express连接可以被配置成x1,x2,x4,x8,x12,x16和x32的数据带宽。x1的通道能实现单向312.5 MB/s(2.5 Gb/s)的传输速率。Xilinx公司的Virtex5系列FPGA芯片内嵌PCI-ExpressEndpoint Block硬核,为实现单片可配置PCI-Express总线解决方案提供了可能。 本文在研究PCI-Express接口协议和PCI-Express Endpoint Block硬核的基础上,使用Virtex5LXT50 FPGA芯片设计PCI Express接口硬件电路,实现PCI-Express数据传输

The power of programmability gives industrial automation designers a highly efficient, cost-effective alternative to traditional motor control units (MCUs)。 The parallel-processing power, fast computational speeds, and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control (FOC)。 Additionally, Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing (DSP) that can tackle compute-intensive functions such as PID Controller, Clark/Park transforms, and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving, proven, motor-control reference designs. The kit also shortens the process of developing custom control capabilities, with integrated peripheral functions (Ethernet, PowerLink, and PCI® Express), a motor-control FPGA mezzanine card (FMC) with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators, and prototyping support for evaluating alternative front-end circuitry.

The Kannel Open Source WAP and SMS gateway works as both an SMS gateway, for implementing keyword based services via GSM text messages, and a WAP gateway, via UDP. The SMS part is fairly mature, the WAP part is early in its development. In this release, the GET request for WML pages and WMLScript files via HTTP works, including compilation for WML and WMLScript to binary forms. Only the data call bearer (UDP) is supported, not SMS.

mp3设计程序资料,采用c语言编写。 README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27. This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it s maximum at 1F40 bytes. A .ROM file is included if you don t have the compiler set up. For now, the documentation is in the code
