This paper presents a safe and efficient solution to manage asynchronous configurations of dynamically reconfigurable systemson-chip. We first define our unified RTOS-based framework for HW/SW task communication and configuration management. Then three issues are discussed and solutions are given: the formalization of configuration space modeling including its different dimensions, the synchronization of configuration that mainly addresses the question of task configuration ordering, and the
