乒乓球比赛游戏机 摘要 现场可编程门阵列（Field Programmable Gate Array, FPGA）是一个崭新的、富有生机的嵌入式系统设计技术研究方向。本文在阐述可编程逻辑器件特点及其发展趋势的基础上，引入了基于嵌入式处理器内核和xilinx FPGA 的SOPC 软硬件设计技术，为基于FPGA 的嵌入式系统设计提供了广阔的思路。本课程基于FPGA的SOPC（System-on-a-chip）技术构造一个乒乓球游戏机,要求用指定的FPGA平台结合SOPC技术构造一个乒乓球游戏机，FPGA通过两条I/O信号输出两组脉宽调制波，经过低通滤波器提取脉宽调制的均值电压，输入到双通道示波器中。示波器工作在X/Y模式,屏幕上的光点代表乒乓球,乒乓球在X/Y电压的控制下在屏幕上移动。在EXCD1开发板上设计使用两个按钮分别作为左侧击球钮和右侧击球钮当乒乓球靠近屏幕左边时按下左侧击球钮，可将球击回右侧右侧击球钮亦然。建立记分机制，在七段数码管上显示双方得分关键字： FPGA VHDL 乒乓球比赛 游戏机 Abstract Field programmable gate array (Field Programmable Gate Array, FPGA) is a new and vibrant direction of embedded system design technology.?This paper describes the development of programmable logic device characteristics and trends, based on the introduction of embedded processor cores based on the SOPC and Xilinx FPGA hardware and software design, FPGA-based embedded system design provides a broad way of thinking.?This course is FPGA-based SOPC (System-on-a-chip) technology to construct a table tennis game, requiring combination with the specified FPGA platform technology to construct a table tennis game SOPC, FPGA through two I / O signal output groups?PWM wave, after a low pass filter from the mean pulse width modulation voltage input to the dual-channel oscilloscope.?Scope of work in the X / Y mode, the representative points of light on the screen table tennis, table tennis in the X / Y control voltage moving across the screen.?Development board designed for use in EXCD1 two buttons as left and right side of the ball hitting button near the left of the screen when the table tennis ball, press the left button, you can hit the ball right back, hitting the right button is no different.?And create scoring mechanism, the seven-segment LED display two scores.Keywords: FPGA SOPC development board table-tennis game EXCD1 目 录 设计任务与要求 1.1 设计任务·················································4 1.2 技术指标········································
