Vision system scans cars from road perspective News & Analysis 5/4/2004 Post a comment Northrop Grumman Corp. (Knoxville, Tenn.) has put a new spin on automotive vision technology with color systems that use the roadway rather than the vehicle to examine the underside of a vehicle. From that novel vantage point, the systems can use a camera to read a vehicle's license plates. Chuck Murray has this report.
Soft errors become hard truth for logic News & Analysis 5/4/2004 Post a comment Those nasty neutrons that have plagued memory chip designers for the past two decades are now giving logic designers a headache, too. But while error correction coding has reduced soft-error rates (SERs) in DRAMs and SRAMs, no such quick fix exists for logic, and all current solutions involve extra cost and a drag on performance. EE Times' semiconductor editors are on the case.
Global chip market up March-to-March News & Analysis 5/4/2004 Post a comment The three-month average of global semiconductor sales in March was $16.275 billion, according to numbers published by the European Semiconductor Industry Association (ESIA), which cited statistics from the World Semiconductor Trade Statistics (WSTS) organization. Peter Clarke has this report.
The digitization of analog and RF circuits Product News 5/3/2004 Post a comment When discussing the integration of analog and RF into digital system-on-chips, it is usually analog that emerges as the most important. However, changes in digital processing are shifting that focus. During the past several years, designers have been working to design simpler analog and RF systems by transferring resources and operations to the digital domain, particularly in the case of wireless basestation design.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
