| FORMAL OPENING OF CONFERENCE | 8:30 AM |
| 1.1 | The New Frontier Created by High-Bandwidth Digital Video Systems and Services | 8:45 AM |
Haruo Nakatsuka, Toshiba Corp., Kawasaki, Japan
Digital video systems have been motivated by the needs of high-quality
pictures. In the future, however, they will play more important roles in
digital home electronics with much more sophisticated services backed up by
advanced high-bandwidth technology.
Passive data services, such as HDTV, are the present focus of the digital
broadcast business. This type of application is met by MPEG2 encoding/decoding
implemented by current LSI technology. More sophisticated applications such as
interactive TV, with 3D capability and intelligent data handling at the viewer
site, require LSIs with higher bandwidth. A 100M polygon/s processor and
40GB/s memory at the viewer site enables services such as TV-linked games,
virtual shopping malls, and 3D cartoons without overloading the transmission
medium. Mixed-reality image processing with smooth fusion of live moving image
data and cartoon graphics requires sophisticated 3D modeling technology.
Another high-bandwidth application is real-time video-image indexing and
filtering for the home server. To recognize and set the index to the live
image data requires DSPs that are 102 to 103 times
faster.

| 1.2 | Is High-Speed the Only Solution to Exploit the Intrinsic Computational Power of Silicon? | 10:15 AM |
Dr. Theo Claasen,
Philips Semiconductors B.V., Eindoven, The Netherlands
The progression of silicon technology has resulted in the emergence of
computation-intensive digital systems that in turn challenge the progression in
technology. Computational intensity eventually is the main reason for
unsatisfiable demand for bandwidth. The computational power of silicon usually
is exploited by increase of synchronous digital circuitry clock speed. What is
the intrinsic computational power of silicon and how can it be exploited? This
raises questions of the effects of speed on power dissipation and suggests
alternatives to brute compute power through architectures exploiting
concurrency, be it parallelism or serialism (pipelining). Flexibility issues
such as architectural reconfigurability and programability are also involved.
In this spectrum of architectures, software and "software-friendliness" will be
addressed from the points of view of CPU, DSPs and mediaprocessors. Such
devices are key to system solutions targeted at a wide range of applications.
The introduction of the Silicon System Platform concept places these key
components in perspective and shows how an heterogeneous composition in an
overall communication structure may be the solution for systems-on-a-chip
allowing maximum reuse of hardware and software. The concepts will be
illustrated by examples from relevant application areas such as interactive
digital TV, optical storage, set-top-boxes and handheld communication systems.
Process technology and manufacturing technology will advance to provide these
capabilities cost-effectively in products for the end-customer.
| 1.3 | Broadband Communications ICs: Enabling High- Bandwidth Connectivity in the Home and Office | 11:05 AM |
Dr. Henry Samueli, Broadcom Corporation, Irvine, CA
The broadband revolution is here. High-bandwidth connectivity will
dramatically change the modes of life and work. Within the home, broadband
services are driven by both the television set and the personal computer.
Availability of digital programming content transforms the television set from
a broadcast-only to a fully interactive appliance. Availability of
multimedia-rich data services on the Internet drives the demand for
high-bandwidth remote-access PC connections via cable and xDSL modems. In the
office, there is also an ever-increasing need for high-bandwidth communications
to accommodate the explosive growth of network connections worldwide. Local
area network technologies such as Fast Ethernet and Gigabit Ethernet are being
developed to relieve these bandwidth bottlenecks.
Satisfying the need for these broadband services has required significant
advances in the levels of mixed-mode IC integration. Deep submicron
technologies have enabled cost-effective multi-million transistor ASICs with
multi-billion operations per second of signal processing capabilities that
would have occupied racks of hardware not that many years ago. As a result,
broadband digital communications is being transformed from specialized military
applications to commodity consumer products. This talk reviews current designs
and future design challenges for achieving the ambitious goal of universal
broadband connectivity.

A 29mm2 16Mb divided bit line NOR (DINOR) is fabricated
using 0.25µ m triple well 3-layer metal technology. Read access time is
82ns at 1.8V. A poly diode charge pump technique improves pump efficiency and
eliminates the body effect problem.

A 32kB embedded flash memory module uses 0.35µm technology for 32b
RISC microcontroller. This module operates at 90MHz with 3.3V supply, using
shielded bit line and symmetrical bit line architecture with a differential
sense amplifier.
