  Growing power dissipation due to high performance requirement of processor
suggests multicore processor technology, which has become the technology for
present and next decade. Research advocates asymmetric multi-core processor
system for better utilization of chip real state. However, asymmetric multi
core architecture poses a new challenge to operating system scheduler, which
traditionally assumes homogeneous hardware. So, scheduling threads to core has
become a major issue to operating system kernel. In this paper, proposed
scheduling algorithms for asymmetric multicore processors have been
categorized. This paper explores some representative algorithms of these
classes to get an overview of scheduling algorithms for asymmetric multicore
system.
