St Quentin-en-Yvelines, France Atmel has expanded its global positioning systems (GPS) offering with a 14-channel, GPS baseband IC that carries a 5 dollar price tag and three-meter accuracy. The Baldur chip is priced about 45% lower than any other comparably featured GPS baseband IC. The chip was developed jointly with Thales Navigation for Thales' Magellan® eXplorist handheld GPS units. Thales licensed the GPS IP to Atmel in December of 2004. The Baldur GPS baseband IC achieves horizontal resolution of as little as one meter, corrected, and three meters, autonomous. Vertical resolution is five meters (corrected) and velocity is measured to within 0.1 meters/second. The chip's superior acquisition (-137 dBm) and tracking (-150 dBm) sensitivities are possible because Baldur can receive and process signals from as many as 12 different tracking satellites at the same time. Additionally, it has two Satellite-Based Augmentation System (SBAS) channels for Wide Area Augmentation System (WAAS), European Geostationary Navigation Overlay Service (EGNOS) or Multi-functional Transport Satellite Augmentation System (MSAS).

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
