Resumo/Abstract
Most currently available
multi-core chips are
homogeneous, but, in order to improve the efficiency for different
applications, processors will have in the future to offer cores with
different characteristics and architectures. Some features of these
architectures may be dynamically configured at a coarse-grain level,
namely by morphing the processor within a set of possible
configurations. Reconfiguration includes basic techniques, namely for
adjusting the operating frequency and the number of active cores, as
well as more complex dynamic mechanisms to configure the memory and the
microarchitecture.
This talk addresses the opportunities and challenges of reconfiguration
to adapt particular features of multi-core architectures.
Apart
from discussing the work that has been done so far, we also foresee the
future of efficient multi-core processors: they will have the
ability to dynamically morph to different configurations, and
virtualization will play an important role. A software virtualization
layer can be used as a wrapper to hide the complexity of this hardware
reconfiguration as well as to monitor the requirement of the
applications. Besides orchestrating the execution of the applications
given the available multi-cores and their characteristics, this
software layer also adapts the hardware to their demands.
