A viable real-time image acquisition system was introduced in this paper. The EP2C35F6728C8 was usesd in this system as the core processor. By using the VHDL language and giving a simulation effect in the circumstances of QUARTUS, the collection and cache of original image was completed in the system, which could ensure the continuity and integrity of the image data. With a simple external interface circuit, it is very convenient for people to use and transplant this system. What’s more, it is also highlighted for its lower power consumption and higher speed. Thus it can be widely used in video surveillance and other fields.

Image processing system to calculate the volume, real-time high and the requirements of small size, using the DSP-based processor, FPGA approach, supplemented by the processor design of a high-performance real-time image processing system, and the system In the process of image acquisition and transmission of noise, using the PCB's anti-jamming design. Practice shows that two chips using FPGA + DSP, the algorithm is divided into two parts by the FPGA and DSP processing; effectively improve the efficiency of the algorithm. System real-time high, adaptability, real-time image acquisition system can meet the design requirements.

This paper introduces a design of a high-speed image acquisition system based on Avalon bus which is supported with SOPC technology. Some peripherals embedded in Avalon bus were customized and utilized in this system, such as imaging unit, decoding unit and storage unit, and these improved the speed of the whole imaging system. The data is compressed to three-fourths of the original by the decoding unit. A custom DMA is designed for moving the image data to the two caches of the SDRAM. This approach discards the method that FIFO must be put up in the traditional data acquisition system. And therefore, it reduced the CPU’s task for data moving. At the same time, the image acquisition and the data transmission can complete a parallel job. Finally, the design is worked on the high-speed image acquisition system which is made up of 2K*2K CMOS image sensor. And it improved the image acquisition speed by three ways: data encoding, custom DMA controller and the parallel processing.

The image acquisition and porcessing system is implemented by combining the embed technology and image technology.This image acquisition system use S3C44B0X which base on ARM for its core proeessing,make use of the CMOS image sensor to collect images,it stores the image data for the moment with FIFO, resolves the rate problem between ARM and the sensor.In the system,CPLD are taken advantage of. This set of equipment combines functions of image acquisting,image displaying and network transferring and has an excellent expansibility which easy to be developed secondly.

Considering the influence of the environment for the search-rescue robot to perform tasks, design scheme of the acquisition module for vision navigation system was determined. In the design, FPGA ping-pong operation method was used. The EP4CE15 main control chip module was completed with module method, and the software design of the system was completed, including Quartus II image acquisition project navigator and Nios II system configuration. Finally, the simulation of data transfer was carried on. Simulation results show that the embedded real-time image acquisition is stable.
