Abstract

In a multi-FPGAs based remote sensing image realtime compression system, high-speed circuit design is carried out and a variety of signal integrity problems caused by system impedance discontinuity are analyzed. On the foundation of transmission line impedance control, taking the high-speed bus of DDR2 SDRAM as an example, signal reflection problem brought by impedance mismatch of the signal chain has been solved through HyperLynx software simulation and analysis. In this system, signal integrity problem caused by system impedance mismatch is effectively solved and reliability of the system is obviously improved, thus it achieves the expected goal of hardware design.
