Abstract
Multicore platforms, which include several processing
cores on a single chip, are being widely touted as a so­
lution to heat and energy problems that are impediments
to single­core chip designs. To accommodate both paral­
lelizable and inherently­sequential applications on the same
platform, heterogeneous multicore designs with faster and
slower cores have been proposed. In this paper, we consider
the problem of scheduling soft real­time workloads on such
a platform.
1. Introduction
Given the thermal and power problems that plague
single­processor chip designs, most major chip manufactur­
ers are investing in multicore technologies to achieve higher
system performance. A number of systems with a modest
number of cores are currently available, and in the coming
