中文说明：实现串口的数据采集，基于分段非线性权重值的Pso算法，对球谐函数图形进行仿真,是国外的成品模型，实现用SDRAM运行nios，同时用SRAM保存摄像头数据，主要为数据分析和统计。
English Description：
Series of data acquisition, Pso algorithm based on piecewise linear weights, to simulation of the spherical harmonic function, is abroad in the finished model, using SDRAM running Nios, while cameras with a SRAM save data, primarily for data analysis and statistics.
