示波器设计源工程
说明: 示波器设计,首先,AD模块对模拟信号进行采样,触发电路根据采样信号判断触发条件。满足触发条件后,连续采样一定数量的点(本系统中为640个点),存储到RAM中。峰峰值、频率计算模块对RAM中储存的波形数据进行计算,得到波形的频率以及峰峰值;VGA模块将波形显示出来,并显示计算得到的峰峰值和频率数值。(Firstly, the ad module samples the analog signal, and the trigger circuit judges the trigger condition according to the sampling signal. After meeting the trigger conditions, a certain number of points (640 points in this system) are sampled continuously and stored in RAM. The peak to peak and frequency calculation module calculates the waveform data stored in RAM to obtain the frequency and peak to peak of the waveform; the VGA module displays the waveform and displays the calculated peak to peak and frequency values.)

基于FPGA分布式算法FIR滤波器verilog代码
(本人 小论文 代码,通过验证)
本文提出一种新的FIR滤波器FPGA实现方法。讨论了分布式算法原理,并提出了基于分布式算法FIR滤波器的实现方法。通过改进型分布式算法结构减少硬件资源消耗,用流水线技术提高运算速度,采用分割查找表方法减小存储规模,并在Matlab和Modelsim仿真平台得到验证。
为了节省FPGA逻辑资源、提高系统速度,设计中引入了分布式算法实现有限脉冲响应滤波器(Finite Impulse Response, FIR)。由于FIR滤波器在实现上主要是完成乘累加MAC的功能,采用传统MAC算法设计FIR滤波器将消耗大量硬件资源。而采用分布式算法 (Distributed Arithmetic, DA),将MAC运算转化为查找表(Look-Up-Table, LUT)输出,不仅能在硬件规模上得到改善,而且更易通过实现流水线设计来提高速度。因此本文采用分布式算法设计一个可配置的FIR滤波器,并以31阶的低通FIR滤波器为例说明分布式算法滤波器结构。( FPGA verilog )

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.)
