Abstract

A kind of driver design method of CMOS image sensor based on PCI bus was introduced.PCI bus,the characteristic and basic using method of PCI9054 chip were presented in detail.Furthermore,the design methods of driver and application of PCI bus were given.Meanwhile,the driver research of image collection sensor OV6620 was discussed,and the designs and timing diagram of FPGA for OV6620 were given.The results show that the design of the image real-time collection system based on PCI bus can be used to accelerate the speed of image data transmission,and the bottleneck of image real-time collection was settled.
