Kandou Recognized for "Best European Paper" at ISSCC 2015

SAN FRANCISCO, CA--(Marketwired - Mar 2, 2015) -  Kandou Bus received the Jan Van Vessem Award for Outstanding European Paper last week at the International Solid-State Circuits Conference. The Solid-State Circuits Society (SSCS) of the Institute of Electrical and Electronics Engineers (IEEE) recognized Kandou for their 2014 paper entitled "A Pin- and Power-Efficient Low-Latency 8-to-12Gb/s/wire 8b8w-Coded SerDes Link for High-Loss Channels in 40nm Technology." Founder and CEO Amin Shokrollahi accepted the award on behalf of Kandou.

"Chord Signaling is a new approach to chip-to-chip interconnect and many of the implementation challenges were different from traditional approaches. Our architecture and physical design teams did an outstanding job building this chip and proving the capabilities of Chord Signaling in silicon," said Shokrollahi. "We thank the SSCS and the IEEE for recognizing Kandou for this significant accomplishment."

At the completion of strenuous test and characterization, Kandou's test chip demonstrated that Chord Signaling is robust and flexible, providing new opportunities for system architects to improve overall performance while consuming less power. Kandou has begun productization of Chord Signaling with its first hard IP optimized for in-package chip interconnect. The solution, which utilizes Kandou's 5-bit over 6-wire "Glasswing" Chordal Code, will deliver 125Gbps and consume less than one pico-Joule per bit of energy. The IP will be fully tested, characterized and available for implementation in customer silicon later this year.

Chord Signaling Fundamentals

The core of Kandou's Chord Signaling™ technology is a chordal code in which correlated signals are sent across more than two wires. Through a simple yet elegant comparator network, signals are received and translated into bits resulting in much higher overall link throughput. Bandwidth can be increased by a factor of 2-4X and power can be reduced by 50 percent or more which allows for improved board, pin and silicon area efficiency as compared to existing technologies. The approach also delivers excellent signal integrity with both strong resistance to common-mode noise and a reduction in simultaneous switching noise. 

To fully realize the benefits of Chord Signaling Kandou has developed optimized circuits and architectures for all parts of the transmission chain including serializers, drivers, receivers, CDR units, skew mitigators, equalizers, deserializers and test circuits. Statistical simulation, time domain and PLL tools have also been developed to provide architects the ability to optimize Chord Signaling solutions to specific system needs.

Applications of Chord Signaling range from in-package chip interconnect to multiple next generation memory interfaces to backplane and even to long haul links. Chord Signaling is also easily adaptable to the unique requirements of virtually any chip-to-chip interface.
