What happened at Pioneer-Standard?
Product News  
2/10/2003   Post a comment
While many factors probably contributed to Pioneer-Standard Inc.'s recent decision to unload its industrial-components distribution business to Arrow Electronics Inc., a key factor may have been the lack of a global infrastructure and the time and the huge dollar investment needed to overtake leading competitors.

Combining RPR and Vcat to Right-Size Sonet Pipes
News & Analysis  
2/6/2003   Post a comment
While hailed as a savior, VC does not fully optimize the delivery of Ethernet and on Sonet links. Fortunately, by merging RPR, MPLS, and VC, designers can bridge this gap. Here's how!
Partitioning extends utility of JTAG scan chains
News & Analysis  
2/5/2003   Post a comment
A system test bus ties together many the products of many manufacturers - JTAG programmable FPGA's, Emulators, ICs with JTAG features, as well as ATPG hardware and software. It enables capabilities like interconnect test, flash programming, emulation, in-system-programming to be accessed at-speed. National Semiconductor's app note suggest how BIST, IEEE P1149.6 (AC Extest), and the IEEE 1149.4 mixed signal test set can all be accessed from a five-wire bus.
How many bits do you need? A discussion of precision for digital audio filters*
News & Analysis  
2/5/2003   Post a comment
Unlike conventional analog systems, in which signals can vary between minimum and maximum values in continuous time, digital audio systems use finite precision in representing signals and coefficients and in performing arithmetic operations. Consequently, audio system performance is determined by the precision that is used throughout the system. This TI presentation discusses the fixed point arithmetic hat influence the performance of Infinite Impulse Response filters in high end audio applicat
Developing Broadband Wireless Equipment: A Case Study
News & Analysis  
2/5/2003   Post a comment
To succeed in providing an effective last-mile wireless solution, designers must build systems that simultaneously support voice and data services. This article provides a real-life look at the tradeoffs engineers will face when developing broadband wireless systems.

The introduction of transparent photonic switching into communications networks is sure to provide savings in several areas.
Optical packet switching lowers next gen IP network costs
Design How-To  
2/3/2003   Post a comment
As the Internet transitions from a best-effort network to a strategic global IP infrastructure, demands will not only be for higher bandwidth, but also for a wider range of integrated services demanding mission-critical reliability.

2/3/2003   Post a comment
For telecommunications systems to transition from 10-Gbit/second to 40-Gbit/s rates, signal paths using all-optical switches are becoming increasingly attractive.
Improving optical switching with independent control planes
Design How-To  
2/3/2003   Post a comment
Currently, many next generation optical switches or cross connects support elements of an embedded proprietary control plane, a standard GMPLS control plane to peer with other vendor's network equipment, and/or OIF UNI/NNI interfaces to interconnect domains and network boundaries.
Dynamic channel equalization improves OADM/optical switch designs
Design How-To  
2/3/2003   Post a comment
The slowdown in telecommunications spending clearly indicates that increased bandwidth capacity will not automatically translate into increased demand for the optical components and subsystems needed to enhance the network infrastructure in place today.
Automated optical switching system can reduce test lab costs
Design How-To  
2/3/2003   Post a comment
Testing optical equipment in the R&D, certification and manufacturing labs of vendors and communication providers is traditionally a manual process that is time consuming, capital-intensive and error-prone.
A case for using hybrid optical switching in long-haul networks
Design How-To  
2/3/2003   Post a comment
There is a fundamental difference between using transparent elements at line sites — degree two junctions with only two fibre directions — and using them at switch sites that have a degree greater than two with three or more fibre directions.

With the widespread penetration of wireless networks, the emphasis now has shifted to "connecting the dots" by allowing seamless roaming between both wide- and local-area networks. Fortunately, many options are available to enable that.
Synopsys opens Milkyway, takes tool interoperability step
News & Analysis  
2/3/2003   Post a comment
Synopsys Inc. this week will open its Milkyway database to EDA vendors, customers and universities, a major step forward for interoperability among electronic design automation tools. Synopsys is also pledging to work with the OpenAccess Coalition to "converge" the Milkyway and OpenAccess application programming interfaces, suggesting that there won't be a single IC database standard, but there will be a high level of integration.
