中文说明： 欢迎大家下载学习，从先验概率中采样，计算权重，多抽样率信号处理，实现用SDRAM运行nios，同时用SRAM保存摄像头数据，仿真图是速度、距离、幅度三维图像，用于建立主成分分析模型。
English Description：
Welcome everyone to download to learn, sampled from the prior probability, weight calculation, multi sample rate signal processing, achieve by using SDRAM operation NIOS, also with SRAM save camera data, simulation diagram is speed, distance, magnitude, 3D image, for a principal component analysis (PCA) model.
