Simulation and Synthesis Techniques for Asynchronous FIFO Design

基于FPGA/EP2c5的开发板详细例程，内容丰富，简单易懂(Development board based on more routine FPGA/EP2c5, content rich, easy to understand)

对于已获得的脉冲包络采样序列，需测量的脉冲特征参数主要有：脉冲幅值(PA)、脉冲到达时间(TOA)和脉冲宽度(PW)。实际测量中，脉冲波形的形状是各种各样的，但其主要的参数有脉冲幅度、脉冲宽度、脉冲周期、脉冲占空比、脉冲前沿(上升时间)、脉冲后沿(下降时间)、脉冲上冲、脉冲下冲、脉冲下垂、脉冲顶部不平度等，脉冲参数的计量主要就是对这些参数进行计量。本程序包实现基于FPGA实现脉冲宽度和重复周期的测量。(Who have access to the pulse envelope sample sequence, the pulse measurement to be the main characteristic parameters are: pulse amplitude (PA), pulse time of arrival (TOA) and pulse width (PW). The actual measurement, the pulse shape is a wide variety of shapes, but its main parameters of the pulse amplitude, pulse width, pulse period, pulse duty cycle, pulse leading edge (rise time), pulse along (down time), the red pulse, pulse undershoot, pulse droop, pulse irregularities, such as at the top, the measurement of pulse parameters is mainly the measurement of these parameters. The package FPGA-based pulse width and repetition to achieve the measurement cycle.)

说明：  FPGA程序的top.v文件，主要实现DDS信号发生器功能，通过定时器，可简单实现输出幅值无极跳变(FPGA procedures top.v documents, the main function of DDS signal generator, through the timer can be simple to achieve the output amplitude wuji hopping)

通过摄像头图像的提取，在FPGA开发板上实现的，主要实现了图像轮廓的提取(Extraction of the image through the camera, in the FPGA implementation of the development board, the main achievement of the image contour extraction)
