Configuration management for networked reconfigurable embedded devices

Abstract

Distribution of product updates to embedded devices can increase product lifetimes for consumers whilst increasing revenues and brand loyalty for vendors. Dynamic provisioning of application solutions to embedded devices are complex due to their heterogeneous nature. This paper proposes a configuration management architectural framework which incorporates a mobile agent based push methodology for networked reconfigurable embedded devices. FPGAs (Field Programmable Gate Arrays) are hardware components within embedded systems that can be dynamically reconfigured. Product updates are composed of both software and reconfigurable hardware code which can be tailored to the physical constraints of the device. Push technology is a distribution mechanism initiated by the vendor enabling delivery of product updates. The proposed infrastructure is built upon the solid foundations of agent-based design patterns. Agent technology provides an ideal environment for embedded systems management. Mobile agents completely encapsulate hardware-software based solutions providing a coherent abstraction for their distribution. The paper also outlines an initial demonstrator system. © Springer-Verlag 2004.
