Multiple Patterns, Multiple Trade-Offs
By David Abercrombie - 11 Dec, 2014 - Comments: 0

As the saying goes, “There is no such thing as a free lunch.” That is a reality that chip designers have had to live by from the beginning. From the advent of the first design rule, it was clear that you couldn’t just do anything you wanted. In the end, everything comes down to trade-offs. Whether it’s area, speed, leakage, noise sensitivity, or drive current, doing something to impr... » read more

Blog Review: Dec. 10
By Ed Sperling - 10 Dec, 2014 - Comments: 1

ARM's Brad Nemire takes a look at a variety of the latest smart devices. Check out the intelligent frying pan that tells you the temperature, the amount of time needed to cook something, and when it's done. Check out the "Homey," too. You can now give verbal commands to your home. Just don't tell it to roll over. Who needs paper? Or more accurately, who needs more than one sheet of paper—e... » read more

Security Risks Grow Worse

Semiconductor Engineering sat down to discuss security issues for connected devices with Marc Canel, vice president of security at [getentity id="22186" comment="ARM"]; Paul Kocher, president and chief scientist for the Cryptography Research division of [getentity id="22671" e_name="Rambus"]; Michael Poitner, global segment marketing manager at [getentity id="22499" e_name="NXP"]; Felix Baum, h... » read more

Top-down Design Of Distributed Embedded Systems In Light Of Timing Considerations
By Mentor, a Siemens Business - 09 Dec, 2014 - Comments: 0

Proper safeguarding of safety-critical systems in an automotive environment cannot be ensured sufficiently without taking timing into consideration. The failure to observe timing constraints can lead to malfunctions and, in a worst-case scenario, can cause vehicle damage and personal injury. AUTOSAR 4.0 now supports timing constraints, but the standard, although very powerful, still is not able... » read more

The Week In Review: Design/IoT
By Ed Sperling - 05 Dec, 2014 - Comments: 0

Tools Calypto rolled out its third-generation high-level synthesis platform after three years of development, adding granular control over which regions are optimized and the ability to work top-down and bottom-up—basically allowing designers to zoom in and out as needed. In addition, the tool has a 10X increase in capacity and supports SystemC and C++. eSilicon unveiled its online conf... » read more

Week 26: A Surge For Embedded At DAC
By Anne Cirkel - 05 Dec, 2014 - Comments: 0

A few weeks ago I told you about the best kept secret at DAC—the fact that about 30% of our content at DAC is focused on embedded systems and software. This came as a surprise to a lot people and shortly afterwards we were contacted by Rich Nass who is the executive vice president and brand manager of embedded computing design at Open Systems Media and the former editorial director for ESC �... » read more

Signal And Power Integrity Cross Paths
By Ed Sperling - 05 Dec, 2014 - Comments: 2

Signal integrity and power integrity historically have been relatively independent issues, and engineers with expertise in one area generally operate independently of the other. But as more power domains are added to conserve energy and allow more features, as voltages are reduced to save battery life, and as dynamic power becomes more of a concern at advanced nodes, these worlds are suddenly m... » read more

Problems Lurk In SoC Boundaries
By Brian Bailey - 04 Dec, 2014 - Comments: 0

Interfaces always have been a problem, because only rarely does anyone have responsibility for them. Responsibilities generally are tied to functional blocks with the prevailing notion that if all blocks do the right thing, they will also behave correctly when brought together. Design teams that believe this eventually find out the fallacy of this assumption. To make matters worse, these are of... » read more

Energy Harvesting Makes Progress
By Ed Sperling - 04 Dec, 2014 - Comments: 0

The dream of a self-powered device has been around for a long time—thousands of years, in fact. The first windmills and waterwheels date back to ancient Greece and the beginning of recorded history. Self-winding timepieces date back to the late 1700s. The Foucault pendulum has been in motion in Paris, minus some brief hiatuses, since 1851. And it's been 144 years since two French physicists d... » read more

Blog Review: Dec. 3
By Ed Sperling - 03 Dec, 2014 - Comments: 0

Mentor's Robin Bornoff zeroes in on some of the biggest and most frustrating causes of energy loss—the ones that have nothing to do with the intended task. In electronics, it's a question of how much power is consumed pushing around electrons and photons. Cadence's Richard Goering follows a panel discussion about whether we're really making progress in low-power design, where the challeng... » read more
