Abstract
This paper aims to provide a quantitative understanding
of the performance of image and video processing applica­
tions on general­purpose 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 instruction­level 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
