Dynamically Reconfigurable Energy Aware Multimedia Information Terminals
Energy management in portable multimedia communications devices is
becoming more and
more critical and complex, with the convergence
of computing and
communication technologies, particularly when video
signal processing
and secure communications are integrated. DREAM-IT
research recognizes
that the best configuration of a portable device
depends on the
environment in which it operates.
The research focuses on transmission of video information in three
applications
settings: background file transfers, streaming, and real-
time. It considers
the two communications systems that will carry the
majority of traffic
in wireless Internets: cellular networks and wirless
local area
networks(WLAN). Examining four technologies that affect battery
life-source compression,
channel coding,encryption, and radio transmission
- the research
maximiazes battery life while meeting quality of service(QoS)
targets. It
considers three platforms for implementing signal processing
algorithms: general
microproccessors,digital signal processors, and field
progammable gate
arrays(FPGA).
