基于VHDL的点阵控制

实现dds功能，利用quartus软件， 子模块包括加法器，锁相环，date-rom 利用原图将各模块综合，利用ps2键盘控制频率及相位。-Dds realize functions, using Quartus software, sub-modules including the adder, phase-locked loop, date-rom image to the module using integrated, using ps2 keyboard to control the frequency and phase.

用DE0开发板实现电话计费器，基本功能：可设置通话模式，能初始化话费余额，拨动开关可进入通话模式，并根据通话时间和相应通话模式扣除相应的费用。通话过程中能够通过开关切换显示通话时间和话费余额，并可暂停通话。压缩包里有详细的WORD文档的说明，包括波形仿真和DE0的引脚功能介绍。(Implemented by DE0 board telephone billing, basic function: to set the call mode, you can initiate credit balance, toggle switch into the talk mode, and deduct the cost of a call based on call time and the corresponding mode. Call talk time and can be displayed by switching credit balance, and mute. Compression bag has a detailed description of WORD documents, including the waveform simulation and DE0 pin function description.)

我的项目执行 filtrage 和抽取使用多相分解，在这种情况下，抽取因子被带到 5，所以筛选器由 5 集团过滤器和每个 oprates 在频率采样除以 5

FPGA设计中的60进制计数器，通过2个七段数码管系那是出来。代码简单易懂，仿真通过，而且在FPGA开发板上加载显示成功。很有用的入门代码。
