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.
