[Technology In The News] ASSET Helps Establish Boundary-Scan Initiative
ASSET InterTech recently became one of the founding members of the International Electronics Manufacturing Initiative’s (iNEMI) boundary-scan adoption project. The initiative—a consortium of over 70 manufacturers, suppliers, and related organizations—started the project to encourage greater use of the IEEE 1149.1 boundary-scan standard (commonly known as JTAG, after the Joint Test Action Group, which defined the original specification).

August 28, 2008[Editorial] For Consumer Electronics, The Holidays Start In July
As an editor with a major electronics magazine, I’m invited to industry events all the time. Come July, though, I start receiving invitations from public relations folks for events that are really outside the magazine’s coverage—events that show the hottest consumer electronics items for the coming holiday season. I can’t resist the temptation. Could you? SAMSUNG HOLIDAY IN JULY Samsung Electronics recently held its...

August 28, 2008[Ideas For Design] Narrow-Shift Digital Discriminator Detects Differential GPS Corrections
The U.S. Coast Guard transmits differential corrections to GPS signals (DGPS) via low-frequency (285- to 325-kHz) beacons. Transmission data rates are 100 or 200 bits/s. The modulation is minimum-shift keying (MSK), resulting in a pseudo frequency-shift keying (FSK) with a carrier shift of half the bit rate. For a 100-bits/s signal, the carrier shift is only ±25 Hz. With a receiver IF frequency of 1 kHz, the IF signal shifts between 975 and 1025 Hz. The...

August 28, 2008[Design View / Design Solution] Eye-Diagram Analysis Speeds DDR SDRAM Validation
Double-data-rate synchronous dynamic random access memory (DDR SDRAM) physical-layer testing is a crucial step in making sure devices comply with the JEDEC specification. The ultimate goal is to guarantee interoperability when different memory devices are used together and that they work when powered up. Fundamentally, interoperability begins at the physical layer. For a DDR memory interface, the responsibility of good physical-layer performance falls at...

August 28, 2008[Engineering Essentials] Modern DSP Chips Serve Up Variations On A Theme
Digital signal processors (DSPs) earn their living by doing certain analog jobs better than analog circuitry. In some cases, where analog circuits can’t even be considered for a task due to cost or complexity reasons, DSPs are still a viable choice and in many cases perform those tasks effortlessly. That’s because DSPs are very good and very fast at arithmetic operations such as addition and multiplication. Clever mathematicians and engineers exploit this...

August 28, 2008[Leapfrog: First Look] 45-nm Via-Programmable ASICs Add High-Speed I/O Transceivers To Feature Mix
ASIC design starts have plummeted in recent years, and there are many good reasons why. Designs at ultra-deep-submicron process nodes are awfully expensive and getting more so daily as mask costs rise, software content proliferates, and verification takes longer. Meanwhile, the steady rise of application-specific standard products (ASSPs) has also contributed heavily to the ASIC’s marketshare slide. Thus, many designers have turned to alternative...

August 28, 2008[TechView: Digital] Cold, Dense, And Gratis MCU Core Targets FPGAs
Did you know that at 5515 kg/m3, Earth is the densest planet in our solar system? Most of that density is made up in the Earth’s core, which became so dense during the early stages of the Earth’s 4.5 billion-year life in a process called planetary differentiation. During this process, and while the Earth was still a ball of molten elements, denser substances such as iron sank toward the center, and the dense core as we know it today was formed. Not to be...

August 28, 2008[Engineering Feature] Portable Craze Redefines The Dashboard
TText, blog, or twitter hands-free while driving. Access your car’s iPod media player to change tracks and adjust the volume without lifting a finger. Even host a three-way telephone call via a Bluetooth device without your hands leaving the steering wheel. No longer content with standard features for low-end and mid-range cars, drivers expect satellite navigation, multizone climate control, satellite radio, and even beverage refrigeration as standard items. ...

[Web Exclusive] Consumer Electronics Growth Tied To Better Design Coordination With Chip Suppliers
When it comes to designing new products, the consumer electronics (CE) and semiconductor sectors of the industry are going to have to get their acts together—literally, according to a joint study by the Consumer Electronics Association, the Global Semiconductor Alliance, and KPMG LLP, an audit, tax, and advisory firm. The study notes that CE producers are designing and developing their products much faster than IC suppliers can design the chips that drive them.

[Web Exclusive] A Summary Of The DDR Memory Controller Standard—Wait, There Isn’t One!
The number of SoCs that require an interface to off-chip memory is increasing. As a result, more and more designers are turning to DDR SDRAM interfaces such as DDR, DDR2, and DDR3 to address their low-cost, security of supply, storage capacity, and performance requirements. Fortunately for those designers, DRAMs have been standardized since the 1970s. But this still leaves a challenge that most SoC engineers don’t recognize until things start to go wrong.

[Designed In] RFEL Digital IC Replaces Analog IF In Spectrum Analyzer
The latest spectrum analyzer from LIG Nex1 employs RF Engines Ltd.’s advanced SpectraChip IF design to replace the instrument’s analog IF filtering section. Replacing traditional analog components with modern digital techniques helps to make the systems easier to manufacture, more reproducible, and more reliable, according to RFEL.

August 14, 2008[Ideas For Design] Driver Offers Proportional Solenoid Control Without PLC, Microcontroller
The proportional-control solenoids used in some industrial hydraulic systems are usually driven by microcontrollers or programmable logic controllers (PLCs). Such complex drivers typically require several different supply voltages for logic and control. (The purpose of proportional control is to move the solenoid plunger to an arbitrary position and leave it there.) A set-and-leave solenoid driver, however, should not require a costly PLC or the...

August 14, 2008[Design View / Design Solution] Build A Debug And Trace Systems For Multicore SoCs
Embedded designers put microprocessors in everyday products like cars, phones, cameras, TVs, music players, and printers, as well as the communications infrastructure, which the general public doesn’t get to see. They know how important it is for their products to work—and work preferably better than their competitors’ products. But the systems-on-a-chip (SoC) behind them continue to grow in complexity, making that simple goal harder to achieve, ...

[TechView: Digital] Multistandard Wireless Accelerator Enables Emerging Basestation Technologies
A famous cartoon coyote once called Apetitius Giganticus wanted to catch a roadrunner that sometimes went by Accelerati Incredibilus. The coyote always used some outdated technology to try to catch the roadrunner, who relied on speed and simplicity to avoid becoming lunch. So if FPGAs and ASICs are the coyote and Freescale’s MSBA8100 wireless basestation accelerator is the roadrunner, then, well, you get the picture.

July 24, 2008[Editorial] CEA Gives Downtown Manhattan A Digital Boost
In the first installment of what promises to be a yearly commitment to New York City’s downtown area, the Consumer Electronics Association (CEA) kicked off Digital Downtown for press and analysts. Digital Downtown was conceived as a three-day showcase of consumer technology, open and free to the general public. The first day of the event, June 12, was warm and sunny. I took a subway to the general area and then had to walk quite a few blocks. As I continued...

July 24, 2008[Engineering Feature] Security Everywhere
Security is a high priority at the China Olympics, and it will be everywhere. The Beijing Municipal Public Security Bureau said last year that it expects to spend $300 million to $400 million on Olympic security, with at least $30 million of that for video security. American companies have been working with Chinese companies to design and install one of the most sophisticated public surveillance systems in the world. General Electric, Honeywell, IBM, and United Technologies...
