Abstract: In order to improve the efficiency of the data storage and reduce bus power consumption, a kind of memory architecture with the characteristics of shared storage, circular storage, and global double buffering mechanism has been presented,which is based on the analyses of transmission characteristics of FC -AE bus rely on PON structure.The experimental results show that this architecture has merits of high reliable performance,low delay time and low power dissipation,by testing the co -verification platform with the hardware and software.
