[POV: Point Of View] Should Dual Rail Go Mainstream in Deep Nanometer Era?
Deep sub-nanometer designs are stressed with large process variability. SRAM-bits have the most aggressive design rules in the SoCs, and the most variability. A dual rail solution offsets some of the variability at the cost of additional design efforts. Dual rail solutions appear to be complex, but several area, power, and performance tradeoffs can be made to simplify the design.

June 25, 2009[Technology Report] Match Multicore With Multiprogramming
Across the embedded landscape, the design credo has become “more cores.” However, challenges remain when it comes to the software side. Some hardware architectures can deliver dozens of cores, while others hit thousands of cores. Unfortunately, applications don’t always port easily across different architectures. For the low end of the embedded space, single-core solutions will remain. It’s still possible to move up the power and performance curve by moving to...

June 25, 2009[Lab Bench] My E-mail Ate My Homework
I’m becoming more forgetful these days— or rather my e-mail is (Fig. 1). Like many of you, I work for a company that limits the lifetime of e-mail. At first, this seems reasonable. It saves space, even though hard-disk prices per terabyte are falling faster than a fully populated NAS box. It’s also a great way to eliminate evidence. This policy has some unintended consequences, though, for...

June 25, 2009[Leapfrog: First Look] Nonvolatile Storage Doesn't Require Transistors
The CMOx nonvolatile memory technology from Unity Semiconductor targets storage-class memory applications. CMOx is based on new materials in the semiconductor process called conductive metal oxides that use the movement of ionic charge carriers to store information. With 64-Gbit chip capacity on the horizon, it looks to be a challenger to NAND flash. The technology employs a multi-layer, multi-level cell (MLC) approach that gives...

[Technology In The News] Germanium Gate-Stack Technology Provides High Carrier Mobility
Toshiba Corp. announced this week that it has made advancements in its development of a gate stack and interlayer with high carrier mobility that can be applied to metal-insulator-semiconductor field-effect transistors (MISFETs) in future generations of LSIs. The ultra-thin, high-k/Ge gate stack and strontium germanide (SrGex) interlayer can provide the high carrier mobility needed for application in MISFETs at the 16-nm node and beyond.

June 18, 2009[Technology Report] Electronics Helps Foster Decentralized Healthcare
Rising healthcare costs, a stretched-thin number of medical providers, longer life expectancies, and a growing number of elderly and disabled patients are transforming the face of medical care. Decentralization—moving healthcare away from medical facilities and into the patient’s home—is fast becoming the new model. In 2008, Medicaid spending for long-term care cost $99.5 billion, according the U.S. Department of Health and Human Services. ...

June 18, 2009[Technology Report] Auto Electronics Revs Up For "Greener" Pastures
The automobile and electronics industries are struggling mightily through this economic tumult. Straddling these two giants, however, is a shining beacon—auto electronics. At last year’s Convergence Conference, a panel of experts from General Motors, Ford, Chrysler, Honda, and BMW suggested that the cost of electronics in a car will increase beyond the oft-quoted 20% figure and climb to 40% to 50%. Getting more extreme, Honda senior...

June 18, 2009[Editorial] How Do We Get Out Of This Mess? Try New Ideas
Life if full of unassailable assumed truths, and it’s an often disturbing but always constructive exercise to challenge them. Let’s start by questioning an easy one from everyday life: are you a good driver? Your instinctive answer is undoubtedly yes, and you would receive the same answer from anyone else you ask. But there are obviously loads of hopeless drivers on the roads. It just so happens that you, or anyone that’s asked, isn’t one of...

June 11, 2009[Leapfrog: First Look] Storage Technology Begins To Crystallize
It’s not in stores yet, but Freescale Semiconductor hopes its silicon crystal approach to flash memory will address the scaling issues that can be found with current approaches. The continuing demand for nonvolatile storage will likely mean this technology will be employed sooner than later. The floating-gate approach to NOR flash implementations is vulnerable to extrinsic reliability fallout as scaling increases. Likewise, the processing ...

June 11, 2009[Embedded in Electronic Design] Chip Links PCI Express And USB
The OXPCIe200 PCI Express (PCIe) bridge links a 1x PCI Express host to a pair of USB host interfaces or one USB host interface and an SPI/SRAM interface (see the figure). The bridge also provides access to a serial port and eight generalpurpose I/Os (GPIOs). The bridge’s dual-USB mode provides one high-speed and one full-speed USB 2.0 host interface. The high-speed interface has a...

June 11, 2009[Embedded in Electronic Design] Common-Law Accelerator Offloads DSP
Adding a Control Law Accelerator (CLA) to Texas Instruments’ line of C28x DSPs can boost performance in applications such as motor control, LED lighting, and digital power by a factor of five. This allows the TMS- 320F2803x chip to handle more demanding applications or deliver high performance with lower power requirements. The F2803x family’s C28x DSP core delivers 60 MIPS. Compared to the F2802x, the newer siblings provide peripheral ...

June 11, 2009[Embedded in Electronic Design] NAND Delivers Capacity And NOR Capabilities
Samsung’s Flex One NAND has moved to 40 nm. It combines multi-level cell (MLC) and single-level cell (SLC) flash with an SRAM front end providing NOR functionality, including the ability to run applications directly. The Flex One uses a 2-kbyte SRAM cache to implement SLC flash. Designers can configure the flash memory split into SLC (code and data) and MLC (data) partitions. MLC storage density is twice the 1-bit/cell total for the SLC...
