基于VHDL的点阵控制

代码是一个复数乘法器，两个复数相乘，只用到了2个实数相乘，运算量少(Code is a complex multiplier, two complex multiplication, uses only real number multiplied by 2, operations less)

说明：  实现在屏幕上显示绿色和红色相间的水平条纹。其中，vga_640x480模块将产生行同步信号hsyn和场同步信号 vsync; vga_stripes模块将产生red、green和blue三个输出。(The horizontal stripes of green and red are displayed on the screen. Among them, vga_640x480 module will produce line synchronization signal Hsyn and field synchronization signal vsync; vga_stripes module will produce red, green and blue three outputs.)

文件名：ADC0809.vhd功能：基于VHDL语言，实现对ADC0809简单控制说明：ADC0809没有内部时钟，需外接10KHz~1290Hz的时钟号，这里由FPGA的系统时钟（50MHz）经256分频得到clk1（195KHz）作为ADC0809转换工作时钟。-File name: ADC0809.vhd features: Based on the VHDL language, easy to control implementation of the ADC0809 Description: ADC0809 internal clock does not need external 10KHz ~ 1290Hz clock number, here by the FPGA system clock (50MHz) frequency by 256 points to be clk1 (195KHz ) as the conversion ADC0809 clock job.

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)

说明：  串口操作源代码，本代码采用veilog hdl语言编写，并经过本人多次验证。(source code, the code used veilog HDL language, and after I repeatedly verified.)
