When it comes to choosing between FPGAs and ASICs, both technologies have their pros and cons. Ultimately it is the designer's decision as to which one will help get the product to market on time or better yet, before the competition does. Q: In high-volume consumer electronic devices, which is the best technology to use: FPGA Design Flow or ASIC Design Flow? By John Burton, Vice President of Marketing for Octera Solutions The answer of course is 'It depends'.
Incorporating touch into a wireless product design introduces additional complexity with radios, antennas and the attendant higher power consumption. By Bruce DeVisser, Fujitsu Components America, Inc. Figure 1. Identifying early-on where a wireless touch device is primarily being designed to perform will help to quickly bring together the right touch parameters.
By Svenn-Tore Larsen, Chief Executive Officer, Nordic Semiconductor Like many organizations in today's electronics sector, my company, Nordic Semiconductor, is rising to the challenge of operating in a global semiconductor market that analysts say could drop by around 20 percent this year compared to 2008.
By considering packaging in the early stages of product development, design teams can determine the best architecture for their particular application. By Ralph Ebbutt, Maxtek Components Corp. click to enlarge Figure 1 - An example of a system-on-chip (SoC) device.
Using advanced battery technologies to unlock the dynamic growth potential of remote wireless sensors used in "smart infrastructure" and related applications. By Sol Jacobs, Tadiran Batteries Contrary to all the recent economic news, the February 17, 2009 edition of The Wall Street Journal contained an upbeat article by Michael Totty entitled "Smart Roads.
There are inherent risks when it comes to wireless technology in medical electronic devices – security, performance, coexistence, EMI and privacy. Q: What are the requirements for effectively deploying and managing wireless medical devices? By R. Srinivasan, Principal Software Engineer, Cambridge Consultants Nowhere are the demands on wireless technology more complex and more critical than in the medical device industry.
By Todd Mersch, Continuous Computing So here we are in the second half of 2008 why are femtocells not more widely deployed in our homes? When are we finally going to get five bars in the family room? And what’s keeping us from quicker YouTube downloads in our kitchens? click to enlarge Figure 1.
Nancy Maas Editor-in-Chief The Mobile World Congress Show (MWC) recently took place in Barcelona, Spain. Every year this show has its "hot topics" that attendees just can't seem to get enough of, and this year was no exception. Conversations focused on handsets, Long Term Evolution (LTE), Location-Based Services (LBS), social networking, application stores and mobile advertising.
The introduction of new radio technoloiges, like OFDM and MIMO, in LTE and WiMAX systems has created the need for new types of test equipment. George Reed, Azimuth Systems click to enlarge Figure 1. Three methods of testing transmitter and receiver performance: lab-based, direct cable connectivity, over-the-air testing and lab-based, connection through a channel emulator that simulates real world conditions.
By Danny Tseng, Cypress Semiconductor Designing a platform with modularity in mind is one approach that can shorten design time as well as enable easier feature upgrades. click to enlarge Figure 1. Architecture modularization of a mobile handset.
Consumer Audio Devices from TVs to Docking Stations to Personal Computers Benefit from the Use of FIR Filters in Providing High Quality Audio at a Reasonable Cost By QuickFilter Technologies, Inc. The U.S. market for consumer electronics goods is approximately $161B and growing at a rate of 8% per year (Consumer Electronics Association Digital America 2008).
The recent advent of low-cost FPGAs equipped with high-performance transceivers and DSP blocks will greatly reduce the build and deployment costs of a video broadcast system. By Shakeel Peera, Lattice Semiconductor Corporation click to enlarge Figure 1.
Greater access to digital audio data off-chip presents an opportunity for applying powerful digital enhancement techniques which can improve speaker performance not just for music but also for voice. By Robert Hatfield, Wolfson Microelectronics In some mobile phone architectures, the evolution of speaker drive technology has recently been struggling to make progress.
In order to market Mobile TV and Mobile Video successfully, service providers and technology companies need to target the specific entertainment needs people have when away from home, rather than just assuming that the populace will be willing to sign up regardless. By Mike Green, European Correspondent Wireless Design & Development The DVB-H infrastructure needed to support video transmission has been in place in Europe for over three years now (it was first showcased to the public at the Winter Olympics in Turin, in February 2006, with crowds being able to tap into the video broadcasts of all the different events taking place).
