VHDL FPGA 流水灯实验

对于中断技术有非常详细的讲解，带图片完整版(Technology for the interruption of a very detailed explanation, with pictures full version)

说明：  基于OV5640摄像头的视频图像传输存储以及读取。供大家参考。(Video image transmission, storage and reading based on ov5640 camera. For your reference.)

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.

ps2接口源程序。标准的键盘和鼠标接口，在Xilinx SpartanII XC2S200 实验板上通过验证-ps2 interface source. Standard keyboard and mouse interface, in the experiments on-board Xilinx SpartanII XC2S200 validated

5对于进入密码锁的钥匙，假设复位后七节灯显示为" 0"，而使用sw1、sw2两个，则sw2-> sw1-> sw1-> sw2，则表示解锁右侧将导致七节灯显示为" 8"

说明：  FPGA按键延时模块，产生key_value和key_flag 可直接例化调用(The key delay module of FPGA)

比较详细的阐述了图像压缩的原理,并基于DSP和VHDL实现该系统,最后在FPGA上通过.(More detailed exposition of the principles of image compress, and VHDL-based implementation of the system, and finally in the FPGA.)
