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: The Fast Fourier Transform (FFT) is one of the
rudimentary operations in field of digital signal and image
processing. Some of the very vital applications of the fast
fourier transform include Signal analysis, Sound filtering, Data
compression, Partial differential equations, Multiplication of
large integers, Image filtering etc.Fast Fourier transform
(FFT) is an efficient implementation of the discrete Fourier
transform (DFT). This paper concentrates on the development
of the Fast Fourier Transform (FFT), based on Decimation-In-
Time (DIT) domain, Radix-2 algorithm, this paper uses VHDL
as a design entity, and their Synthesis by Xilinx Synthesis Tool
on Vertex kit has been done. The input of Fast Fourier
transform has been given by a PS2 KEYBOARD using a
testbench and output has been displayed using the waveforms
on the Xilinx Design Suite 12.1.The synthesis results show that
the computation for calculating the 32-point Fast Fourier
transform is efficient in terms of speed. Platform: |

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: |
