This paper will discuss the design of an asynchronous FIFO,Asynchronous FIFOs are widely used in the computer networking industry to receive data at a particular frequency and transmit them at another frequency. An asynchronous FIFO has two different clocks: one for read and one for write.-Asynchrinous FIFO design

WiMAX, or the IEEE 802.16 standard for broadband wireless access, is increasingly gaining in popularity as a technology with significant market potential. This paper first provides an overview of the existing and developing 802.16 standards and their key differences/applications. The PHY and MAC layers of a typical WiMAX base station are then described. The associated implementation challenges faced by WiMAX infrastructure developers, including performance/cost/flexibility trade-offs in the choice of silicon, are clearly outlined. The paper then describes how FPGA-based system implementation can address these challenges including the “accelerated time-to-market” requirement which is considered a key enabler for early success in this market. As an example design, the physical layer implementation of the 802.16d standard with Altera FPGAs and intellectual property (IP) is proposed.

用S7-200PLC的自由口模式和VB中的MSComm控件方便地实现了计算机与S7-200（CPU224）PLC的通讯。计算机作为主站,用户通过计算机可以方便地设置房间的控制指令并向PLC发出控制或监测命令， PLC作为从站来响应计算机发送的指令并采取相应的动作并将房间的电、水、热信息发回到计算机。用户可以通过电脑屏幕实时地监视到房间的电、水、热信息并进行相应的处理。-with S7-200PLC the Free Port Mode and the VB MSComm to realize a trap Computer and S7-200 (CPU224) PLC communications. Computer as a master station, Computer users can easily set up control rooms PLC issued directives to control or monitoring orders, PLC as from the station to respond to orders sent by the computer and take corresponding action will be room for electricity, water, Heat fat information to the computer. The user can screen real-time surveillance of the room electricity, water and heat information and handled accordingly.
