USB Interface with FPGA for Data Acquisition System Using in X-Ray Applications

Abstract

The image processing system with acquisition, transmission and display was designed based on the new type CMOS image sensor and USB2.0 controller. Using the OmniVision OV9715 CMOS image sensor as photoelectric imaging device, glueless connecting was achieved between the USB2.0 controller CY7C68013A and the sensor by general programmable interface (GPIF). The simple high efficiency and low-cost hardware which be adapt for high speed image capture was designed and the software system was also compiled based on the multi-thread technology. This project attempts to develop a novel solution to the image acquisition system catering to the X-ray applications. The salient features of this project is to attempt to build an acquisition system that are reconfigurable, and can adapt to any kind of CMOS sensor.
