For LAN switch manufacturers, Vertex Networks has released the first two chips in its third-generation XpressFlow 2001 series of 10/100-Mbit/s Ethernet switch chipsets: the SC-201 XpressFlow Engine and the EA-224 four-port 10/100-Mbit Fast Ethernet Access Controller. The switch chipsets, with a highly scaleable and flexible architecture, are built around the XpressFlow Bus providing from 1.05 to 1.6 Gbit/s of data bandwidth. The devices support up to 12 10/100Mbit Fast Ethernet ports, a combination of 10- and 100-Mbit ports, or up to 56 10-Mbit Ethernet ports. The SC-201 resolves destination MAC addresses (using an embedded high-density instruction set core processor optimized for network applications) and VLAN membership of incoming data packets. The EA-224 provides four access ports, buffers data, and handles MAC protocols. Vertex Networks: Product Code 4315

Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
