1. LED的显示原理： 16×16扫描LED点阵的工作原理同8位扫描数码管类似。它有16个共阴极输出端口,每个共阴极对应有16个LED显示灯，所以其扫描译码地址需4位信号线（sel0-sel3），其汉字扫描码由16位段地址（l0-l15）输入。 通过时钟的每列扫描显示完整汉字。 2. 本试验实现输出“欢迎光临”四个汉字，采用两种格式输出：（1）依次从右向左连续输出；（2）单个汉字从上及下刷新输出。 -1. LED display Principle: 16 × 16 dot mat

用CUDA计算数组的并行求和运算，在下个数据输入前进行上一次的数据计算-This example demonstrates an efficient CUDA implementation of parallel prefix sum, also known as "scan". Given an array of numbers, scan computes a new array in which each element is the sum of all the elements bef

Prefix sums are trivial to compute in sequential models of computation, by using the formula yi = yi − 1 + xi to compute each output value in sequence order. However, despite their ease of computation, prefix sums are a useful primitive in certa
