Editors' Introduction: Hot Chips 19 (pdf) by Raj Amirtharajah, University of California, Davis, and John
Mashey, Techviser
This special issue showcases articles written from five of the best
presentations at the Hot Chips 19 conference, held in August 2007. The guest
editors give highlights of the conference and introduce the articles, which
cover the mobile-optimized northbridge of AMD's Griffin microprocessor family;
the IBM z10 next-generation mainframe microprocessor; fault tolerance in IBM's
Power6 microprocessor; NVIDIA's Tesla unified graphics and computing
architecture; and SiBEAM's 4-Gbps 1080p-capable uncompressed HD A/V wireless
60-GHz transceiver chipset.

4-Gbps Uncompressed Wireless HD A/V Transceiver
Chipset(pdf) byJeffrey M. Gilbert, Chinh H. Doan, Sohrab Emami, and C. Bernard
Shung, SiBEAM
Wireless transmission of uncompressed lossless HD video provides higher image
quality with lower latency and cost than compressed-content transmission.
However, it requires data rates of about 4 Gbps for 1080p resolution, exceeding
the capabilities of existing wireless technologies. Using the 60-GHz band as
detailed by the Wireless HD specification, SiBEAM's chipset makes such data
rates economically achievable.
