Heidelberg, Germany LeCroy has announced the UWBTracer , claimed to be the industry’s first protocol analyzer that supports the new ultra wideband (UWB) WiMedia and Wireless USB (WUSB) standards. The UWBTracer is capable of capturing and decoding WiMedia and WUSB protocols. By capturing traffic between a MAC and PHY, the user can display protocol traffic from boards currently in the design phase. The analyzer software can logically organize and display the protocol hierarchically at the WiMedia and WUSB levels. The CATC Trace software display not only shows the protocol, it also includes information about the WiMedia and WUSB specification. This allows engineers to concentrate on completing their design. Real time statistics provide additional insight into the product’s operation and performance. A wireless extension of the USB PC interface, WUSB can be added on to existing USB products without any modification. With a maximum bandwidth of 480 Mbps at three meters, WUSB can achieve the same performance as a wired high-speed USB connection. LeCroy GmbH , Heidelberg, Germany. www.lecroy.com.
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.
