Abstract
General-purpose processors are expected to be increas-
ingly employed for multimedia workloads on systems where
reducing energy consumption is an important goal. Re-
searchers have proposed the use of two forms of hardware
adaptation architectural adaptation and dynamic voltage
(and frequency) scaling or DVS to reduce energy. This
paper develops and evaluates an integrated algorithm to
control both architectural adaptation and DVS targeted to
multimedia applications. It also examines the interaction
between the two forms of adaptation, identifying when each
will perform better in isolation and when the addition of
architectural adaptation will benefit DVS.
