Dynamically reconfigurable embedded software-does it make sense?

摘要

A dynamically reconfigurable real-time software (DRRTS) paradigm can be used effectively in the design of embedded systems to provide many major advantages over conventional software development techniques. The benefits include rapid development which reduces development time and cost, ability to easily upgrade and maintain embedded software, and both analytic and practical tools for automated analysis and systematic fine tuning of the embedded system. Our current research is founded upon the Chimera Methodology, which demonstrated the feasibility of using dynamically reconfigurable software to control robots. However, there are still many design challenges in order to use it in an embedded system, which has less flexibility, severe limits on memory and CPU bandwidth, and more rigid timing constraints and reliability specifications. We have several ongoing projects which address some of the issues, in a strive towards the overall objective of creating a software infrastructure for developing dynamically reconfigurable embedded software.
