Abstract: Reconfiguration system-on-a-chip (SoC) is an important trend of embedded system.It is not only to achieve the higher performance but also flexible enough.In this paper, a SoPC (System on a Programmable Chip) platform is introduced and a new kind of peripheral bus used for reconfigurable computing is proposed.Using this peripheral bus, we can form a new embedded system easily by changing different intellectual property (IP) cores in a short time.This paper also overviews the process of partial dynamic reconfiguration and accomplishes a reconfigurable system.Finally, we give a result of the reconfiguration time in embedded systems.
