原创By DeeZeng [ Intel FPGA笔记 ] 在用Nios II测试 DDR3时候发现一个现象 (测试为:写全片,读全片+比对) 用单独的PLL产生时钟(200MHz)驱动 Nios II,  测试DDR3时间为87s 用 DDR3 IP的 afi_clk(200MHz) 驱动 Nios II,  测试DDR3时间为67s 只是换了个时钟为什么影响这么大?相差近 20s 分析发现 PLL 产生的时钟 和 DDR3 的afi_clk 是两个时钟域 Qsys interconnect…

n people wish to cross a bridge at night. A group of at most two people may cross at any time, and each group must have a flashlight. Only one flashlight is available among the n people, so some sort of shuttle arrangement must be arranged in order t…

一.概述 桥接模式:将两个原本不相关的类结合在一起,然后利用两个类中的方法和属性,输出一份新的结果. 二.案例 1.模拟毛笔(转) 需求:现在需要准备三种粗细(大中小),并且有五种颜色的比 如果使用蜡笔,我们需要准备3*5=15支蜡笔,也就是说必须准备15个具体的蜡笔类.而如果使用毛笔的话,只需要3种型号的毛笔,外加5个颜料盒,用3+5=8个类就可以实现15支蜡笔的功能. 实际上,蜡笔和毛笔的关键一个区别就在于笔和颜色是否能够分离.即将抽象化(Abstraction)与实现化(Implement…
