Abstract
In recent years, Globally Asynchronous Locally Synchronous (GALS) designs and dynamic voltage scaling (DVS) have emerged as some of the most popular approaches to address the ever increasing microprocessor energy consumption. In this work, we propose two on-line algorithms for adjusting dynamically, and independently, the voltage and frequency of the front-end and back-end domains of a novel two-domain microprocessor. We evaluate our mechanisms for both internal and external voltage regulators, ...
