VGA图象显示控制器设计,实现在VGA显示器上显示图象.

matlab code for communication

说明：  数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

这是“VHDL设计”讲稿，希望对初学者有用，-"VHDL design" script, useful for beginners, thank you! !

实现了四bit计数器的功能，使用的是VHDL语言描述(Four-bit counter, using the VHDL language description)

SPI接口协议，将spi总线转换成为LOCALBUS总线(SPI interface protocol, the spi bus converted into LOCAL BUS bus)

在BASYS3上实现跑马灯的功能。第一LED交替闪烁；第二LED由左至右逐个变亮，再逐个变暗；第三LED由右至左逐个变亮，再逐个变暗；第四LED由两边逐个变亮，再从中间逐个变暗。(Realize the function of the horse light on BASYS3. The first LED flashes alternately; second LED brightens from left to right and then darkens one by one; the third LED turns from right to left, then darkens one by one, and then darkens one by one; fourth LED is brightened by both sides, and then darkening from the middle.)

Floating Point FP multiplication is widely used in large set of scientific and signal processing computation. Multiplication is one of the common arithmetic operations in these computations. A high speed floating point double precision multiplier is implemented on a Virtex 6 FPGA. In addition, the proposed design is compliant with IEEE 754 format and handles over flow, under flow, rounding and various exception conditions. The design achieved the operating frequency of 414.714 MHz with an area of 648 slices.
