Design and Implementation of a High-Speed LVDS Data Acquisition System Based on Virtex-5 FPGA

Abstract:

A High-Speed LVDS Data Acquisition system is designed, with XILINX’s Virtex-5 FPGA as core processor as well as TI’s TMS320C6748 DSP for pre-processing and storing data. This system achieved a greater amount of image processing and faster image processing requirement. The system completed the dual LVDS image data acquisition according to the demand. The resolution of the image data is 320x257. Each image transmission frame rate of not less than 150 / sec. large amount of data throughout the system as well as real-time demanding is a big challenge for designer. The designer uses simulation tools from Mentor Graphics Hyperlynx to complete the stack and impedance calculation and signal quality simulation to ensure that the system is stable and reliable. This system also has better scalability and more reliable storage method than past designs. Recently, the system has completed testing verification and results show that this design is feasible and reliable.
