SAMOS X Special Sessions
Within SAMOS X, two special sessions will be organized on the following topics:
Special Session on Software Defined Radio (SDR) and Cognitive Radio (CR):
SDR is a technique where the physical layer processing of a communications modem is implemented in software. Software implementations of modems enable Cognitive Radios (CR) that can sense their environment, select interference-free frequencies, and dynamically change modulation properties. This special session explores hardware and software technologies required to implement SDR and CR systems including processor design, software design of communication systems, programmable transceiver techniques, and methodologies for implementing systems.
Special Session on Multicore Architectures for Embedded Systems:
Different trends can be observed in the hardware industry for embedded systems, which are presently being required to run several different applications with distinct behaviors, becoming more heterogeneous. At the same time, users also demand an extended operation, with extra pressure for energy efficiency. While transistor size shrinks, processors are getting more sensitive to fabrication defects, aging and soft faults, increasing the costs associated to their production.
In this scenario, different hardware resources must be provided at different levels: to better execute a single thread, according to a given set of constraints at a certain time; to allocate resources and schedule different processes depending on availability, performance requirements and the energy budget; or to sustain working conditions when a fault occurs during run time, or even to increase yield to allow cost reductions even with aggressive scaling or the use of unreliable technologies.
In this special session we want to bring together people working on different complementary domains, and discuss their vision of this common problem in future devices.
