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.
Burning rubber on the SoC freeway News & Analysis 2/10/2003 Post a comment Trading off performance for power has never been an easy task. This week we'll take a look at how some developers are managing to juggle the gigahertz-performance requirements of today's huge system-on-chip designs and the demands those systems make on power consumption.
Adding net functions to GHz chips News & Analysis 2/10/2003 Post a comment With the push to smaller geometries, chip functionality continues to increase. Clock frequencies of 100 MHz at 0.18- and 0.13-micron manufacturing technologies are quite common.
Reaching for the 1 GHz ring Design How-To 2/10/2003 Post a comment Gigahertz design is a very exclusive neighborhood that requires skilled hand-crafting by teams of engineers during all phases of a design.
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.
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.
IP Mobility Ensures Seamless Roaming Design How-To 2/3/2003 Post a comment 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.
A Book For All Reasons Bernard Cole1 Comment Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
