Research on Hi-Speed Image Data Transmission Channel Based on PCI Bus

CTP adopts high-frequency and multi-channel laser to record high-resolution image, however, conventional PC interface can’t meet the requirement of ultra fast transmission for massive data, here, we put forward a novel image data transmission channel based on PCI bus, which utilizes dual data bus, data buffer and hardware-based data collation.This channel consists of PCI bus interface module, data buffer module, data collate calculation module, LVDS transmitter and LVDS receiver, it is simple and low cost. Application and experiment show that the new image data transmission channel reduces the CPU’s processing time for data calculation and operating time for data transmission, and has advantages of fast and reliable data transmission, therefore it is suitable for CTP.
