VHDL language used to achieve 8

这是个vhdl编写的16bit的加减法器-This is vhdl prepared by the modified instruments used in the 16bit

一种基于FPGA的CPU设计-FPGA-based CPU design ........

基于VHDL语言的七段显示管程序， 实现9个数字循环 并且能控制播放速度(SEVEN SEGMENT DISPLAY)

使用VHDL实现锁相环,是个学习VHDL的好例子,与众分享-PLL using VHDL, VHDL is learning a good example, sharing with the public

APB总线协议转I2C总线协议的接口IP，verilog代码实现，包含详细testbench(APB bus interface to I2C bus interface IP，verilog code )

针对某船舶模型定位系统中调速电机，以FPGA(现场可编程门阵列)为控制器，采用数字比例积分调节器实现电机的速度控制算法，设计出数字化调速控制器(Positioning system for a ship model in the motor speed, the FPGA (field programmable gate array) for the controllers, proportional integral regulator with digital speed of the motor control algorithm, designed digital speed controller)

说明：  OFDM的简易verilog仿真程序，环境是quartus，版本需要7.2以上(OFDM Modulation and Demodulation using Verilog in Quartus)

我用的是二进制分频的方法，这种分频方法的分频只能是2n次方，有限制，但是很方便

同步串行数据发送电路SSDT的基本功能是将并行数据转换成串行数据并进行同步发送。系统写入和读出时序完全兼容Intel8086时序。 系统以同步信号开始连续发送四个字节，在发送中出现5个1时插入一个0，在四个数据发送结束而下一次同步没有开始之前，发送7FH，这时中间不需要插入零 -synchronous serial data transmission circuit SSDT the basic function is to convert parallel data into serial and the same this step. System write and read sequential fully compatible Intel8086 timing. Synchronized signal system to start sending four consecutive bytes, in this emerging 5 1:00 insert a 0, at the end of four data sent and the next synchronization not started before, sending seven FH, then the middle is not inserted
