Multimedia applications (speech, video, audio, games, etc)
are one of the key drivers for the microelectronics industry.
Today integrated circuits and systems for multimedia are characterised
by extremely high levels of integration density, often exploiting
the maximum speed and compute power offered by the technology,
and increasingly, merging media processing with on-line network
connectivity. Subsequently, the design process has become the
critical criterion for success in a sector fundamentally driven
by time-to-market / first to market pressures. In order to regulate
the ever-increasing design complexity and to keep the design
effort economical, design teams are creating and employing new
hardware/software co-design methodologies to develop reusable
platform-based solutions.
This Special Day features a full-day track combining a lunch
keynote, special and invited sessions that present the new trends
and challenges in the design of Systems-on-Chips and embedded
systems for multimedia applications, as well as the platforms,
design methodologies and tools that are needed for this. Major
challenges for a successful design of future multimedia systems
that are covered in this special day include embedded multimedia
architectures and platforms, multimedia processors, distributed
processing, hardware/software co-design methodologies, and techniques
to manage timing, QoS and power.
The Lunch Keynote Speech will be given by Professor Ulrich
Reimers, Braunschweig Technical University, Germany. As Chair
of the DVB Technical Module, Professor Reimers is heading the
major international standardisation forum in the field. He will
share his view on the future of multimedia, highlighting a selection
of current trends and developments of multimedia services and
the underlying technical systems.

Broadcasting Project (DVB) Technical Module, Germany |
| A plethora of R&D
activities world-wide aim at designing new, fascinating
and profit-yielding multimedia systems. Acknowledging
the fact that it will be impossible to cover the wealth
of these developments entirely, the speech will highlight
a selection of current trends of development of multimedia
services and the underlying technical systems. Source
coding of audio and video signals plays a fundamental
role in most multimedia systems and significant new
developments can be reported. Which communication
channels will be used for these source encoded signals
and which kinds of terminals will they address? Future
personal communications devices will include medium-resolution
colour displays and therefore will be the ideal terminal
for many new forms of multimedia services. The use
of “hybrid networks” consisting of a 2G,
2.5G or 3G mobile communications network and an additional
broadband downstream will offer tremendous new possibilities
to the user. As Chair of the DVB Technical Module,
the speaker is heading the major international standardisation
forum in the field. He will share his view on the
future of multimedia. |

| The capability to receive,
process and transmit multimedia content on embedded
computing platforms is key to a wide range of applications.
Various challenges that arise in this context on the
system architectures, SoC design, and system software
are presented. Using Philips Nexperia as a case study
an architecture design of a platform optimised for
multimedia delivery is presented. Efficient utilisation
of intellectual property (IP) blocks is key to design
of system-chips for these architectures. A design
framework that enables IP reuse and chip implementations
from IP blocks is described. Next the impact of multimedia
content delivery on the system software from firmware
to middleware services is examined. Specifically,
techniques for maintaining QoS to end-user multimedia
applications (e.g. video streaming, multimedia conferencing)
while maximising device lifetimes, especially in mobile
applications are focused on. Strategies at the architectural,
OS, middleware and application layers are discussed.
Finally, operating system services and their relationship
to middleware services with focus on efficient delivery
of application functionality are examined. |

| This session discusses
multiple applications and methodologies, which are
using reconfigurability to implement wireless and
multimedia functionalities. During the session we
will address the implementation and test of a UMTS
turbo-decoder on a reconfigurable platform following
with the presentation of the implementation of an
MPEG-2 decoder using modulo scheduling algorithms
mapped on a tightly coupled VLIW/reconfigurable matrix.
The session will go on with a number of DCT and motion
estimation implementations that have been mapped to
domain-specific reconfigurable arrays. We will close
with the experiences of mapping complex 1.5 million
to 4 million ASIC gates on very high density FPGAs. |

| Multimedia systems
play a central role in many human activities. Recent
advances in VLSI sparked an increasing demand for
portable multimedia appliances capable of handling
advanced algorithms in all forms of communication
(text, audio, video). In the current SoC technologies,
however, the power constraints and the scarcity of
the computation/communication resources can easily
limit the number of media functions that can be integrated
on the same chip. Power concerns are even more important
for the newly emerging design platforms consisting
of resources that interact across the network and
can be shared by multiple applications. Successful
design of such multimedia applications means then
to find the best mapping of the target application
onto a given set of architectural resources, while
satisfying an imposed set of design constraints and
specified QoS metrics. This special session will address
the fundamental issues that make the design process
particularly challenging and offer a long-term vision
towards a design methodology for distributed multimedia
systems. |
