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: 超声视频图像需要实时地采集并在处理后在显示器上重建,图像存储器就必须不断地写入数据,同时又要不断地从存储器读出数据送往后端处理和显示[11]。为了满足这种要求,可以在采集系统中设置2片容量一样的SRAM,通过乒乓读写机制来管理。任何时刻,只能有1片SRAM处于写状态,同时也只有1片SRAM处于读状态。工作期间,2片SRAM都处于读写状态轮流转换的过程,转换的过程相同,但是状态错开,从而保证数据能连续地写人和读出祯存.-Real-time ultrasound video images need to collect and deal with the reconstruction after the display, image memory must be continually write data, while at the same time continuously sent from the memory读出数据back-end processing and display [11]. To meet this requirement, you can set up collection system capacity of two different SRAM, read and write through the ping-pong mechanisms to manage. At any time, can only have a SRAM in write state, but also the only one at a time the state of SRAM. Work, two SRAM read and write are in the process of converting a state of rotation, the conversion process of the same, but the state staggered to ensure that data can be continuously written and read out Qizhen depositors.

Description: 1). 用红、绿、黄三色发光二极管作信号灯。主干道为东西向,有红、绿、黄三个灯;支干道为南北向,也有红、绿、黄三个灯。红灯亮禁止通行;绿灯亮允许通行;黄灯亮则给行驶中的车辆有时间停靠到禁行线之外。
2).由于主干道车辆较多而支干道车辆较少,所以主干道绿灯时间较长。当主干道允许通行亮绿灯时,支干道亮红灯。而支干道允许通行亮绿灯时,主干道亮红灯,两者交替重复。主干道每次放行50秒,支干道每次放行30秒。
在每次由亮绿灯变成亮红灯的转换过程中间,需要亮5秒的黄灯作为过渡,以使行驶中的车辆有时间停靠到禁行线以外。
3). 能实现正常的、即时显示功能。用DE2上的四个七段数码管作为倒计时显示器。分别显示东西、南北方向的红灯、绿灯、黄灯时间。
4).能实现特殊状态的功能显示。设S为特殊状态的传感器信号,当S=1时,进入特殊状态。当S=0时,退出特殊状态。按S后,能实现特殊状态功能:
(1)显示器闪烁;
(2)计数器停止计数并保持在原来的数据;
(3)东西、南北路口均显示红灯状态;
(4)特殊状态结束后,能继续对时间进行计数。
5).能实现总体清零功能。按下R后,系统实现总清零,计数器由初始状态开始计数,对应状态的指示灯亮。

For the east-west trunk road, has red, green, yellow three lights support for the north-south trunk road, there are red, green, yellow three lights. Red light curfew green permit passage yellow light is to the moving vehicles have the time of call to cut outside the lane.
2). Because of the trunk road vehicles more vehicles and less trunk extension, so a longer green time of a main road. When the main road access permit a green light when the trunk road red sticks. Permit access roads and support a green light when the trunk road red, the two alternating repetition. Allowed 50 seconds for each trunk, branch trunk release each 30 seconds.
