Description: 设计一个6层电梯控制器。电梯控制器是按照乘客的要求自动上、下的装置。
1、每层电梯入口处设置上下请求开关，电梯内设有顾客到达层次的停站请求开关。
2、设有电梯所处位置指示装置以及电梯运行模式（上升或者下降）指示装置。
3、电梯每秒升降一层楼。
4、电梯到达有停站请求的楼层，经过1秒电梯门打开，开门4秒后，电梯门关闭（开门指示灯灭），电梯继续运行，直至执行完最后一个请求信号后停留在当前层。
5、电梯能记忆电梯内外所有请求信号，并按照电梯运行规则按顺序响应，每个请求信号保留至有电梯响应后消除。
6、初始状态为一层开门，第一层不用向下开关，最高层不用向上开关。
7、电梯运行规则：当电梯上升时，只响应比电梯所在位置高的上楼请求信号，由下而上逐个执行，直到最后一个上楼请求执行完毕；如果高层有下楼请求，则直接升到下楼请求的最高楼层，然后进入下降模式。当电梯处于下降模式时与上升正好相反。

Description: 在信息处理中，特别是实时视频图像处理中，通常都要对实现视频图像进行处理，而这首先必须设计大容量的存储器，同步动态随机存储器SDRAM虽然有价格低廉、容量大等优点，但因SDRAM的控制结构复杂，常用的方法是设计SDRAM通用控制器，这使得很多人不得不放弃使用SDRAM而使用价格昂贵的SRAM。为此，笔者在研究有关文献的基础上，根据具体情况提出一种独特的方法，实现了对SDRAM的控制，并通过利用FPGA控制数据存取的顺序来实现对数字视频图像的旋转，截取、平移等实时处理。-In information processing, especially real-time video image processing usually have to deal with video images, which must first be designed large-capacity memory, synchronous dynamic random access memory SDRAM Although there are low cost, large capacity, etc., but SDRAM control structure of the complex, commonly used method is to design generic SDRAM controller, which makes a lot of people had to abandon the use of SDRAM and the use of expensive SRAM. To this end, the authors examine the literature based on the specific situation in a unique way to realize the control of SDRAM, and control data through the use of FPGA to realize the order of access to digital video image rotation, interception, translation, such as real-time processing.

Description: 块DDS芯片中主要包括频率控制寄存器、高速相位累加器和正弦计算器三个部分（如Q2220）。频率控制寄存器可以串行或并行的方式装载并寄存用户输入的频率控制码；而相位累加器根据dds频率控制码在每个时钟周期内进行相位累加，得到一个相位值；正弦计算器则对该相位值计算数字化正弦波幅度（芯片一般通过查表得到）。DDS芯片输出的一般是数字化的正弦波，因此还需经过高速D/A转换器和低通滤波器才能得到一个可用的模拟频率信号。
-In the programming step, the electronic controller fills the memory with data. Each datum is a binary word representing the amplitude of the signal at an instant of time. The array of data in the memory then forms a table of amplitudes, with time implied by the position in the table. If, for example, the first half of the table were filled with zeroes and the second half with values of 100 , then the data would represent a square wave. Any other wave shape can be created simply by altering the data.
Devices are also available that cannot be programmed, and can only output sinewaves or a small number of waveforms.
