Long-wave Heat Detectors High-speed Video Circuit Design And Simulation

In1990, the French the TOSA company’s288×4detector can achieve image resolution of standard PAL video processing circuit based on DSP as the core of the traditional processing circuit. Into the21st century, with the rapid development of the resolution of the detector array, computer, micro-processing technology, network communication, transmission technology and data processing technology, the design of video image processing circuit are constantly upgrading, the frequency range is also constantly improved. In order to improve the overall performance of the system to meet the needs of people in1152×4system using FPGA and DSP integration circuit. This paper studies the long-wave heat detectors video circuit design and simulation.First of all, the board of the other company’s high-speed video analysis of the system to understand the characteristics of high-speed digital circuits, to determine the core chip, according to the needs of the high-speed video board to select a reasonable DSP and FPGA chip.Secondly, the core chip DSP and FPGA performance, reasonable configuration chip design their peripheral circuits and PCB board laminated structure and layout. And draw the schematic and PCB schematic using Cadence software.Finally, the video signal line, the clock signal line, and I\O data transmission line simulation with Cadence Allegro Expert tool. Through the analysis of simulation results, it is reasonable to draw the design of the high-speed video circuit.
