Surprises At Hot Chips 2016


Who would have thought an Intel architect would be on stage talking about cutting pennies out of MCU prices? Or that Nvidia would be trumpeting an automotive SoC whose chief performance advantages come from the integration of ARM CPUs that can support up to eight virtual machines? Or that Samsung would be developing a quad-core mobile processor from scratch based on its own unique architecture?... » read more

Power-Centric Chip Architectures


As traditional scaling runs out of steam, new chip architectures are emerging with power as the starting point. While this trend has been unfolding for some time, it is getting an extra boost and sense of urgency as design teams weigh a growing number of design challenges and options across a variety of new markets. Among the options are [getkc id="196" kc_name="multi-patterning"] and [getkc... » read more

Micro-Architectural Exploration For Low Power Design


By Abhishek Ranjan, Saurabh Shrimal and Sanjiv Narayan In the first part of this series, we discussed the need to perform power optimizations and exploration at higher levels of abstractions, where the potential to reduce the power consumption was highest. While fine-grained local changes (like clock-gating, operand isolation, etc.) for power reduction are well understood and widely adopted,... » read more

Micro-Architectural Exploration For Low Power Design


By Abishek Ranjan, Saurabh Shrimal and Sanjiv Narayan The adoption of finFET technology has created a tectonic shift in the chip design landscape. In addition to better performance (within the same power envelope) and higher reliability, finFETs have significantly reduced the leakage power at smaller technology nodes. At the same time, the share of dynamic power dissipation continues to rise... » read more

A Strategy For Designing For Power With FinFETs


Recently Qualcomm announced their new SnapDragon processor 820, which was designed using finFET technology. They showed some amazing results, such as 2X improvement in performance and 2X improvement in power compared to 28nm designs. Previously, when ARM announced their A72 processors in finFET, they too had claimed 3.5X improvement in power compared to 28nm designs. But can designers expect... » read more

Executive Insight: Sanjiv Kaul


Sanjiv Kaul, president and CEO of [getentity id="22016" e_name="Calypto"], sat down with Semiconductor Engineering to talk about dynamic power concerns in finFETs, where software fits in, and why high-level synthesis is now a competitive requirement at advanced nodes. What follows are excerpts of that conversation. SE: What's the biggest problem the semiconductor industry is facing right no... » read more
