Abstract
Modern system design is being increasingly driven by
applications such as multimedia and wireless sensing and
communications, which all have intrinsic quality of service
(QoS) requirements, such as throughput, error-rate, and resolution.
One of the most crucial QoS guarantees that the
system has to provide is the timing constraints among the
interacting media (synchronization) and within each media
(latency). We have developed the first framework for
systems design with timing QoS guarantees, latency and
synchronization. In particular, we address how to design
system-on-chip with minimal silicon area to meet timing
constraints. We propose the two-phase design methodology.
In the first phase, we select an architecture which facilitates
the needs of synchronous low latency applications well. In
the second phase, for a given processor configuration, we
use our new scheduler in such a way that storage requirements
are minimized. We have develop scheduling algorithms
that solve the problem optimally for a-priori specified
applications. The algorithms have been implemented
and their effectiveness demonstrated on a set of simulated
MPEG streams from popular movies.
