这个是有关于随即信号的文章,里面具体介绍了这个信号的概念,应用等-this is a signal immediately on the articles, which introduced the specific signal to the concept and application

远程升级boot代码跳转部分，GPRS协议部分暂时不用理会，关键是BootLoader代码才是跳转部分，实现flash中A区，B区的切换(Remote upgrading boot code jump part, GPRS protocol part temporarily ignored, the key is BootLoader code is the jump part, realize Flash in A area, B area switch.)

用于测试串口的小程序..用在上位机上-Serial port for testing a small program ..

说明：  quartusII 9.1，位同步提取电路，可以实现位同步时钟提取，其中包括分频器，和由D触发器以及与门组成的鉴相器模块。(Quartus II 9.1, bit synchronous extraction circuit, can realize bit synchronous clock extraction, including frequency divider, phase discriminator module composed of D trigger and and gate.)

大家看看,定有收获哦 我愿 将之与大家分享-you see, there is harvest Oh, I like to share it with you

定时器时间计算工具 使用方便 并有模拟功能 是一个不错的软件-The calculation of time timer tools easy to use and have analog functions is a good software

sdram controller code

c++设计模式，对入门的开发人员有较大的帮助(C + + design pattern is of great help to beginner developers)

说明：  输入椭圆中心和长短轴径; 2. 计算得到中心在原点的椭圆上的第一个点=; 3. 根据公式(1.1.3-2)计算区域1中决策参数的初值为; 4. 在区域1中每个位置处，从开始，反复按照公式(1.1.3-3)更新决策参数，若决策参数小于0则不变，反之加1，一直循环到为止，记第一个满足此条件的点为(); 5. 在区域2的每个位置处，从开始，反复按照公式(1.1.3-6)更新决策参数，若决策参数小于0则不变，反之加1，一直循环到()为止;(Input ellipse center and long and short axis diameter; 2. The first point of the center on the ellipse at the origin is calculated. 3. According to formula (1.1.3-2), the initial value of decision-making parameters in region 1 is calculated. 4. At each location in region 1, the decision-making parameters are updated repeatedly according to formula (1.1.3-3). If the decision-making parameters are less than 0, they will remain unchanged. If the decision-making parameters are less than 0, then add 1 and cycle until the first point satisfying this condition is (); 5. At each location of region 2, the decision parameters are updated repeatedly according to the formula (1.1.3-6). If the decision parameters are less than 0, they will remain unchanged. If the decision parameters are less than 0, then add 1 and cycle until ().)

说明：  卡尔曼滤波算法，画图与Simulink；是一种很好用的估计算法(Kalman filter algorithm, plot and Simulink)
