Kandou resolves today’s chip interconnect performance/power bottleneck for mobile and networking apps

SAN FRANCISCO, USA: Kandou Bus has announced that the first implementation of its breakthrough high-performance, low-power link technology will be introduced at the 2014 International Solid-State Circuits Conference (ISSCC).

In both a technology demonstration and a paper presentation at the conference by Kandou founder and CEO Amin Shokrollahi, Kandou will detail its innovative coding-based signal interface, which significantly outperforms existing I/O solutions.

Shokrollahi leveraged his extensive background in coding-based signaling in the development of the Kandou Chord signaling solution. As chief scientist of Digital Fountain, which was acquired by Qualcomm in 2009, he invented Raptor codes that have since been standardized in almost all modern communication systems.

He has also been recognized multiple times as an IEEE Fellow including receivng the IEEE Hamming Medal in 2012. When he first began analyzing chip interconnect technologies he was surprised to learn that coding-based signaling had not extended beyond differential links, a very simple "code" on only two wires. Further research revealed that traditional copper interconnect interfaces like memory links or SerDes using NRZ or PAM-4 are reaching their technical limits.

"The push for longer battery life, improved graphics and faster downloads in electronic systems has highlighted a critical issue: today's chip-to-chip interfaces are a growing bottleneck," said Shokrollahi.

"System architects and chip designers are having to make sub-optimal bandwidth and power tradeoffs that are affecting products from cell phones to servers. Chord signaling can extend the life of copper for several generations while delivering unprecedented and sustainable link bandwidth improvements and lower power consumption."

Bandwidth and power challenges for next-generation links are being addressed by the industry's leading standards organizations such as OIF, IEEE and JEDEC. Kandou advocates for industry standards, contributing its technology and support via membership and board positions within these organizations.
