Abstract
This paper aims to provide a quantitative understanding
of the performance of image and video processing applica-
tions on general-purpose processors, without and with me-
dia ISA extensions. We use detailed simulation of 12 bench-
marks to study the effectiveness of current architectural fea-
tures and identify future challenges for these workloads.
Our results show that conventional techniques in current
processors to enhance instruction-level parallelism (ILP)
provide a factor of 2.3X to 4.2X performance improve-
ment. The Sun VIS media ISA extensions provide an ad-
ditional 1.1X to 4.2X performance improvement. The ILP
features and media ISA extensions significantly reduce the
