Tool Helps Designers Find Interface Parasitics As nanometer design projects become more commonplace, the side effects of shrinking process geometries also will grow familiar. The emergence of significant interconnect parasitic elements is chief among these effects—especially for 90-nm... — John Blyler September 2004 Entertainment Nears The Consumer Sweet Spot Many consider the wireless home to be the crowning achievement of the engineering future. Currently, numerous engineering companies are working on technologies that will enable wireless audio/video in such a home. Although very impressive... — Nancy Friedrich September 2004 ZigBee Platform Readies Wireless-Based Designs Sometimes, a little can go a long way. For instance, take the case of ZigBee—a set of networking, security, and application software protocols based on the IEEE 802.15.4 low-data-rate wireless standard. Compared to other wireless networks, such... — John Blyler June 2004 FPGA Prototyping Tool Aligns With ASIC Flow Over a third of all high-end ASIC designers now use FPGAs for prototyping 500,000-plus-gate designs. Driving this trend is the fact that a median application-specific integrated-circuit (ASIC) design can now fit onto the largest field-programmable... — John Blyler June 2004 Platform Eases Hands-Free Bluetooth Design What if you could truly have hands-free cell-phone operation while driving down the road? Better yet, imagine that this capability was inexpensive, yet provided high sound quality. Texas Instruments believes that most cell-phones users would welcome... — John Blyler June 2004 ESL Tools Enable Early Software Development Software development is the critical link in the development of today's embedded wireless applications. Some estimates place software creation at 50% to 70% of overall product-development costs. To remain competitive, wireless designers must be able... — John Blyler May 2004 SiGe Challenges GaAs Handset Dominance There was a time when cellular-handset vendors wouldn't have thought twice about using GaAs power amplifiers (PAs) in their designs. Now that silicon-germanium (SiGe) technology has achieved the performance levels of GaAs-based amplifiers, however,... — John Blyler April 2004 Elliptic Cryptography Strengthens Security Most on-the-go, mobile wireless users need to transmit and receive their data with a reasonable level of security. Unfortunately, early wireless security methods like WEP required a great deal of processing power. As a result, users chose to disable... — John Blyler April 2004 C-Code Algorithms Infiltrate Hardware Few areas of embedded design are more challenging than the development of mobile wireless products. In this arena, designers must carefully balance overall performance issues with power consumption and time-to-market pressures. The tools that can... — John Blyler March 2004 RFIC Test System Meets Wireless Needs For one of the hottest growth areas in the semiconductor market, look to radio-frequency integrated circuits (RFICs). These ICs are an essential part of any wireless device—be it a cell phone, laptop, or multimedia product. To ensure that they... — John Blyler March 2004 High-Level Abstraction Comes Into Tool's Grasp Despite the economic downturn of the last two years, the electronic-system-level (ESL) design and verification markets continue to evolve. This fact proves the importance of system-level development software for the electronic-design-automation (EDA)... — John Blyler February 2004 Wireless-Data Demands Force Memory's Rebirth With the number of features in next-generation handsets on the rise, the adoption rate of data-based capabilities is surging. In the handset itself, this trend poses a significant strain for both code execution and data storage. To take some of the... — Cheryl Ajluni November/December 2003 Design-For-Test System Fits Desktop Wireless designers are very well acquainted with time-to-market pressures. In hopes of escaping this familiar tension, they warmly welcome anything that can reduce these pressures—especially if it also lowers product-development costs. Among the... — John Blyler November/December 2003 C Synthesis Nurtures FPGA Development The design starts that use reconfigurable processors—namely field-programmable gate arrays (FPGAs)—continue to grow in popularity. In fact, a recent Gartner Dataquest study found that FPGAs and application-specific signal processors (ASSPs)... — John Blyler October 2003 Alchemy Works Magic On Mobile Devices One of the brightest stars in today's technology constellation continues to be the wireless market. Big and small players alike have joined in the consumer craze for wireless products. New devices are based on everything from 2.5G and 3G technology... — John Blyler October 2003 Coprocessor Synthesis Offloads Software Tasks For experienced wireless designers, the migration path from software to hardware is a familiar one. After all, newer technologies are first implemented in software to gain efficiency and expediency. Examples include Java, multimedia (MPEG-4), and 3G... — John Blyler October 2003 Test-Vector Generation Draws Major Gains To design complex ASICs in a timely and cost-effective manner, engineers must incorporate various design-for-test (DFT) methodologies. Early on, for example, they must add boundary as well as internal built-in self-test (BIST) structures and scan... — John Blyler September 2003 Cellular Memory Swaps In The Next Generation Although they have been hyped for many years, high-data-rate cellular networks are now becoming a reality. As more communities are upgraded with 2.5G and 3G infrastructure systems, consumer interest is growing in the networks' potential benefits. But... — John Blyler September 2003 Gain Amplifier Eyes 30-To-300-MHz Range The rollout of 2.5 and 3G networks is quickly gaining momentum. North America, for example, is witnessing the ongoing build-up of GSM/GPRS cellular network systems. In addition, one major U.S. carrier is in the process of deploying that region's first... — John Blyler July/August 2003 Chip Set Rejects One-Channel Approach As Wi-Fi products continue their remarkable growth rate, so too will the potential for airway congestion. The wireless networks in the enterprise environment and commercial "hot spots" will be particularly susceptible. After all, they have a greater... — John Blyler  prev. page
