| Abstract: | A design idea and realization of the high speed reconfigurable frame synchronizer based on CPLD is presented. How to improve the system speed and reliability is also discussed.We adopt many techniques during the design,including digital interrelated checkup,error tolerable checkout and protection,in system programming.We also use pipeline to improve system speed. Integrating high speed PCI bus interface design,we realize the on line reconfiguration of high speed frame synchronizer. |
