What To Expect In 2012
By Ed Sperling - 15 Dec, 2011 - Comments: 0

By Ann Steffora Mutschler Looking at the biggest challenges for system-level design in 2012, model availability, IP integration and hardware/software co-design top everyone’s list. The integration of IP and enabling that from a system-level perspective is a significant challenge for the industry. Moreover, it will become even more significant as the market moves further down the Moore’s... » read more

Energy Vs. Power: Energy, Power Optimization Is A System-Level Challenge
By Ed Sperling - 01 Dec, 2011 - Comments: 0

By Ann Steffora Mutschler Power issues today, whether they are related to low power in a smart phone or highly efficient power for data center applications, are so pervasive that they touch the entire design team—and must be carefully prioritized at the system or architectural level. As discussed in Part 1 of this series, energy and power are different entities and must be understood dist... » read more

Why Batteries Don’t Last Long Enough
By Ed Sperling - 01 Dec, 2011 - Comments: 0

By Pallab Chatterjee While there have been great strides in process scaling for power reduction on a per-gate level for mobile devices, a large part of the power is still consumed by the power amplifier, filter and analog mux arrangement from the systems. Most of the logic systems have benefited from scaling to the sub-40nm technology range, which reduces standby and operating power by seve... » read more

Cell Phone Radiation: Taboo Topic, Interesting Science
By Ann Mutschler - 01 Dec, 2011 - Comments: 0

Amid a growing consumer concern for possible health issues associated with radiation, more attention is being paid to what’s being generated by mobile devices—particularly the ones we hold next to our brains. Legislation has been introduced in some parts of the country, with varying success, aimed mainly at informing consumers about the potential risks and giving suggestions for reducing ex... » read more

AMS Challenges Growing
By Ed Sperling - 01 Dec, 2011 - Comments: 0

By David Lammers Analog and mixed signal (MS) devices will play an ever-increasing role in saving energy, particularly as the “Internet of Things” expands to about 10 billion units per year over the next decade. But as leading-edge design rules scale to 28nm and below, enhanced with high-k/metal gate technologies, it is becoming increasingly challenging to integrate AMS devices on SoCs. ... » read more

3D DRAM Makers Inch Closer To Production
By Ed Sperling - 01 Dec, 2011 - Comments: 0

By Mark LaPedus For some time, DRAM makers have been developing 3D memory chips, but commercial products still are not due out for some time because of technical and cost issues. But the advent of the 3D DRAM era could be near the turning point, as two memory rivals have separately moved to bring their respective technologies closer to production. In one move, Micron Technology Inc. has di... » read more

Playing The Voltage Game
By Ed Sperling - 01 Dec, 2011 - Comments: 0

y Ed Sperling Scaling down the voltage to boost battery life and cut energy costs has always been considered the best option, but it’s getting more difficult at advanced nodes and in stacked die packages. The key problems are noise and leakage. Lowering the voltage exacerbates both of them, forcing a rethinking of the whole design process starting at the architectural level and continuing... » read more

Make Vs. Buy
By Ed Sperling - 17 Nov, 2011 - Comments: 0

By Ann Steffora Mutschler The confounding ‘make versus buy’ decision is understandably muddled by design complexity. Millions of gates, thousands of blocks, dozens of cores, plus software, packaging, and worries about physical effects don’t make this decision any easier. In some cases the process can be simplified by mandating that anything that doesn’t add differentiation really is... » read more

Content And Gaming Drive Design
By Ed Sperling - 17 Nov, 2011 - Comments: 0

By Pallab Chatterjee This year’s IEDM conference will feature a non-device topic for the luncheon keynote from Masaaki Tsuruta, CTO of Sony on Interactive Gaming. The takeaway: Even in the heavy R&D and physics-centric world of devices, building for the end application has now become one of the top priorities in driving specifications. Traditional compute systems were based on batch-... » read more

Managing IP In Complex Devices
By Ann Mutschler - 17 Nov, 2011 - Comments: 0

By Ann Steffora Mutschler Whether it is a smartphone, tablet, video game with home networking feature or any other digital device, each contains multiple subsystems with a mixture of IP blocks from either in-house development or licensed from third parties. Managing the subsystems, let alone the individual IP blocks and the interplay between all of them, is not getting any easier. In fact, wit... » read more
