ABSTRACT
We present a technique for task response time improvement based on the concept of code motion from the software domain. Relaxed Operation Motion (ROM) is a simple yet powerful approach for performing safe and useful operation motion from heavily executed portions of a design task to less visited segments. We introduce here our algorithm, how it differs from other code motion approaches, and its application to the embedded systems domain. Results of our investigation indicate that cost-guided operation motion has the potential to improve task response time significantly.
