[Software Engineering] FPGAEPP.files DL : 0: USB、串口、并口是PC机和外设进行通讯的常用接口，但对于数据量大的图像来说，若利用串行RS-232协议进行数据采集，速度不能达到图像数据采集所需的要求；而用USB进行数据采集，虽能满足所需速度，但要求外设必须支持USB协议，而USB协议与常用工程软件的接口还不普及，给使用带来困难。有些用户为了利用标准并行口(SPP)进行数据采集，但SPP协议的150kb/s传输率对于图像数据采集，同样显得太低。因此,为了采集数据量大的图像数据,本文采用了具有较高传输速率的增强型并行口协议(EPP)和FPGA，实现对OV7620CMOS图像传感器进行高速数据采集，它最高速率可以达到2Mb/s。-USB, serial port, parallel port is PC and peripherals used for the communication interface, But for the large volume of data images, if the use of Serial RS-232 data acquisition agreement, speed image data can not achieve the requirements for acquisition; using USB for data collection, can meet the required speed, But requirements must support USB peripherals agreement, and USB agreement with the commonly used engineering software interface is not universal, difficult to use. Some users to take advantage of standard parallel port (SPP), for data collection, But SPP agreement of 150 kb / s transfer rate for image data acquisition, the same is too low. Therefore, in order to collect large quantities of data image data, In this paper, the high transmission rate of enhanced parallel port proto

[Software Engineering] ThedesignofUniversalAsynchronousReceiverTransmitte DL : 0: 本课题所设计的UART支持标准的RS．232C传输协议，主要设计有发送模块、接收模块、线路控制与中断仲裁模块、Modem控制模块以及两个独立的数据缓冲区FIFO模块。该模块具有可变的波特率、数据帧长度以及奇偶校验方式，还有多种中断源、中断优先级、较强的抗干扰数据接收能力以及芯片内部自诊断的能力，模块内分开的接收和发送数据缓冲寄存器能实现全双工通信。除此之外最重要的是利用口模块复用技术设计数据缓冲区FIFO，采用两种可选择的数据缓冲模式。这样既可以应用于高速的数据传输环境，也能适合低速的数据传输场合，因此可以达到资源利用的最大化。-According to the characteristics of the UART and the portability advantage of FPGA designs，this paper puts forward an embedded UART design method based on FPGA chips．The design method includes description form of FSM and design approach of Top-Down．It’S good to take advantage of VHDL to program the slave module and top module of UART，and then integrate them into the interior of FPGA chip．In this case it improves not only the disadvantage of the traditional UART chips but also makes the whole system more compact and more reliable．
