Merging Power and Arithmetic Optimization Via Datapath Rewriting (Intel, Imperial College London)
By Technical Paper Link - 19 Apr, 2024 - Comments: 0

A new technical paper titled "Combining Power and Arithmetic Optimization via Datapath Rewriting" was published by researchers at Intel Corporation and Imperial College London. Abstract: "Industrial datapath designers consider dynamic power consumption to be a key metric. Arithmetic circuits contribute a major component of total chip power consumption and are therefore a common target for p... » read more

Application-Optimized Processors
By Ed Sperling - 29 Sep, 2023 - Comments: 0

Executing a neural network on top of an NPU requires an understanding of application requirements, such as latency and throughput, as well as the potential partitioning challenges. Sharad Chole, chief scientist and co-founder of Expedera, talks about fine-grained dependencies, why processing packets out of order can help optimize performance and power, and when to use voltage and frequency scal... » read more

Power Domain Implementation Challenges Escalate
By Ann Mutschler - 20 Jun, 2022 - Comments: 0

The number power domains is rising as chip architects build finer-grained control into chips and systems, adding significantly to the complexity of the overall design effort. Different power domains are an essential ingredient in partitioning of different functions. This approach allows different chips in a package, and different blocks in an SoC, to continue running with just enough power t... » read more

Power-Aware Test: Addressing Power Challenges In DFT And Test
By Rahul Singhal - 10 Aug, 2021 - Comments: 0

Integrated circuit (IC) sizes continue to grow as they meet the compute requirements of cutting-edge applications such as artificial intelligence (AI), autonomous driving, and data centers. As design sizes increase, the total power consumption of the chip also increases. While process node scaling reduces a transistor’s size and its operating-voltage, power scaling has not kept up with the si... » read more

Lower Power Chips: What To Watch Out For
By Ann Mutschler - 08 Jul, 2021 - Comments: 0

Low-power design in advanced nodes and advanced packaging is becoming a multi-faceted, multi-disciplinary challenge, where a long list of issues need to be solved both individually and in the context of other issues. With each new leading-edge process node, and with increasingly dense packaging, the potential for problematic interactions is growing. That, in turn, can lead to poor yield, cos... » read more

Power Optimization: What’s Next?
By Brian Bailey - 17 May, 2021 - Comments: 2

Concerns about the power consumed by semiconductors has been on the rise for the past couple of decades, but what can we expect to see coming in terms of analysis and automation from EDA companies, and is the industry ready to make the investment? Ever since Dennard scaling stopped providing automatic power gains by going to a smaller geometry, circa 2006, semiconductors have been increasing... » read more

Reducing Power At RTL
By Ann Mutschler - 13 Feb, 2020 - Comments: 0

Power management and reduction at the register transfer level is becoming more problematic as more heterogeneous elements are added into advanced designs and more components are dependent on interactions with other components. This has been a growing problem in leading-edge designs for the past couple of process nodes, but similar issues have begun creeping into less-sophisticated designs as... » read more

Managing Power Dynamically
By Ann Mutschler - 18 Dec, 2019 - Comments: 1

Design teams are beginning to consider dynamic power management techniques as a way of pushing the limits on performance and low power, leveraging approaches that were sidelined in the past because they were considered too difficult to deploy. Dynamic voltage and frequency scaling (DVFS), in particular, has resurfaced as a useful approach. Originally intended to dynamically balance performan... » read more

Interdependencies Complicate IC Power Grid Design
By Ann Mutschler - 12 Dec, 2019 - Comments: 0

Creating the right power grid is a growing problem in leading-edge chips. IP and SoC providers are spending a considerable amount of time defining the architecture of logic libraries in order to enable different power grids to satisfy the needs of different market segments. The end of Dennard scaling is one of the reasons for the increased focus. With the move to smaller nodes, the amount of... » read more

Power Complexity On The Rise
By Ann Mutschler - 14 Nov, 2019 - Comments: 0

New chip architectures and custom applications are adding significant challenges to chip design and verification, and the problems are becoming much more complex as low power is added into the mix. Power always has been a consideration in design, but in the past it typically involved different power domains that were either on, off, or in some level of sleep mode. As hardware architectures s... » read more
