Power Management And Integration Of IPs In SoCs: Part 2
By Progyna Khondkar - 14 May, 2020 - Comments: 0

Most IP are available as either soft or hard macros. But both pose immense challenges. This is especially so when integrating them into low power designs and conducting power aware (PA) verification, because the majority of IP are self-contained and pre-verified at the block level and they must be preserved in their entirety when integrated or verified in the SoC level. Part one of this two ... » read more

Meeting The Power Challenges of ADAS
By Maxim Integrated - 06 May, 2020 - Comments: 0

Advanced driver assistance systems (ADAS) technologies have the potential to improve driver safety and comfort, and to reduce car accidents and casualties. The adoption of ADAS technologies creates challenges in electronic solutions size, safety, and reliability. This white paper reviews the challenges for ADAS electronic components of a smart car and presents a few examples of how power man... » read more

The Limits Of Energy Harvesting
By Ed Sperling and Kevin Fogarty - 09 May, 2019 - Comments: 4

Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

Make Your Own Energy
By Ann Mutschler - 02 May, 2019 - Comments: 2

Regenerative braking and other forms of energy capture are becoming more popular and increasingly effective. What started as a way of increasing the range of electric or hybrid vehicles is now being applied to everything from green buildings to industrial robots. The automotive industry is still the main driver of this technology. The idea that braking can generate energy has been around for... » read more

Week in Review: Design, Low Power
By Susan Rambo - 08 Feb, 2019 - Comments: 0

The U.S. Department of Energy (DOE) has awarded $35 million for 12 projects involving ultra-efficient power management. Called Arpa-E, the program encouraged participants to use medium-voltage electricity in new ways with real-world applications, such as industry, transportation and the grid. The top two award winners were Eaton Corp. (Arden, NC) for its DC wide-bandgap static circuit breaker, ... » read more

Hidden Costs Of Shifting Left
By Brian Bailey - 26 Apr, 2018 - Comments: 0

The term "Shift Left" has been used increasingly within the semiconductor development flow to indicate tasks that were once performed sequentially must now be done concurrently. This is usually due to a tightening of dependences between tasks. One such example being talked about today is the need to perform hardware/software integration much earlier in the flow, rather than leaving it as a sequ... » read more

Transient Power Problems Rising
By Ann Mutschler - 08 Jun, 2017 - Comments: 0

Transient power is becoming much more problematic at 10/7nm, adding yet another level of complexity for design teams already wrestling with power issues caused by leakage, a variety of power management techniques to control dynamic power, and leakage current. At each new node there is less headroom for engineering teams to address these problems, and more likelihood that what they do in one ... » read more

Got Energy?
By Grant Pierce - 10 Oct, 2016 - Comments: 0

Energy is a finite resource, which means it’s not someone else’s problem. It’s everyone’s problem. This isn’t just another doom and gloom prediction. Energy consumption has been rising steadily for decades. Unfortunately, it has been increasing at a faster rate than energy production. A Semiconductor Industry Association report entitled, “Rebooting the IT Revolution: A Call to Ac... » read more

Sonics CTO Drew Wingard talks about how to save energy on a very granular level when processing 4K video. [youtube vid=vugyCG5Y_0U] » read more

Time For A DDR Background Check
By Pat Sheridan - 28 Jul, 2016 - Comments: 0

In this month’s blog we continue our discussion of power management, specifically looking at how architects can improve the energy efficiency of their SoC as it uses system memory. In March we teamed up with Micron, a global supplier of high performance, low power memory technologies, to present a tutorial at SNUG Silicon Valley (see proceedings) explaining the practical steps system desig... » read more
