The advantages and the flexibility introduced into the hardware implementation by partial dynamic reconfiguration have rapidly changed the design flow of embedded systems. Configuration management is an important issue in operating system for dynamically reconfigurable system-on-chip. Reconfiguration overhead affects the performance of reconfigurable system. This paper presents a hardware implemented efficient configuration management unit. Wet define our operating system framework based on unified multitask programming model for reconfigurable system-on-chip at first. Then the detailed design and implementation of the configuration management unit are given. Finally a use case is presented, which shows the efficiency of the configuration.
