十六进制7Segment时钟

sdram控制器的开发程序，还有文档，可以参考以下(SDRAM controller development process, there is a document, you can refer to the following)

东芝ccd产品tcd1209驱动程序，生成1209所需的驱动波形(toshiba ccd tcd1209 )

displayport 参考设计，可以对比自己工程做验证，另有参考设计XAPP1178未找到，采用方案为DP159 + Artix7 FPGA(xilinx displayport sink design)

ssb的调制与解调，包括信号的产生、乘法器、加噪、BPF、解调等部分。(ssb modulation and demodulation, signal generation, multiplier, adding noise, BPF, demodulation section.)

16位右移位寄存器 下面描述的是一个位宽为16位的右移位寄存器，实际具有环形移位的功能，是在右移位寄存器的基础上将最低位的输出端接到最高位的输入端构成的。其功能为当时钟上升沿到达时，输入信号的最低位移位到最高位，其余各位依次向右移动一位。(16-bit right shift register The following description is a right shift register with a bit width of 16 bits. It actually has the function of circular shift. It is based on the right shift register, which connects the lowest bit output terminal to the highest bit input terminal. Its function is that when the rising edge of the clock arrives, the lowest displacement of the input signal reaches the highest position, and the rest of you move one bit to the right in turn.)

基于VHDL的数字计时器，手动可控正计时和倒计时(含复位键和使能键)(VHDL-based digital timer and countdown timer being controlled manually (with the reset button and enable key))

由8 位加法器构成的以时序方式设计的8 位乘法器，采用逐项移位相加的方 法来实现相乘的VHDL程序代码。包含几个小模块和一个顶层设计文件，运行可用。(an 8 bit multiplier combined with 8 bit adder using a design by way of timing,and it use a way of Itemized shift to implement the multiply.It include some little module and a top level design document.)

说明：  ADC Reference code!Clock 100kHz

this come from alter ,you can look and find it on line about h263.
