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: 在3D图像处理等对运算要求高的领域，高效除法器已成为处理器内必不可少的部件。在分析除法器设计的泰勒级数展开算法基础上，提出了一种新的除法器设计算法。在满足同样精度的情况下，所实现的三级流水线的除法器，与基于泰勒级数展开算法的除法器相比，面积更小，速度更快。-In 3D image processing and so on, demanding area of computing, efficient divider has become essential components inside the processor. In analyzing the divider design Taylor series expansion algorithm based on a new design algorithm divider. Meet the same accuracy in the cases, the three realize the divider line, and based on the Taylor series expansion algorithm divider compared to a smaller area, faster. Platform: |

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: MATLAB is one of several tools for working with mathematics. As an experienced
programmer, I was skeptical at rst. Why should I learn another programming
language when I could do the work in C/C++? The answer was simple: working
with MATLAB is easier! Yes, there are some instances when one would want to
use another language. A compiled program, such as one written in C++, will run
faster than an interpreted MATLAB program (where each line is translated by the
computer when the program is run). For hardware design, one might want to write
a program in Verilog or VHDL, so that the program can be converted to a circuit. Platform: |
