Data Center Power Consumption: What Effect Does Memory Have?
By Loren Shalinsky - 06 Nov, 2014 - Comments: 1

Data Centers now account for 3% of the worldwide power consumption, up from an estimated 1.5% just a few years ago. Data centers have been getting more efficient, but the efficiency has been hidden by the large growth in the number of data centers. The question that was recently posed to me: What effect does memory have on data center power consumption? I’ll cut straight to the chase. T... » read more

Energy Boost For Power Standards
By Brian Bailey - 09 Oct, 2014 - Comments: 0

If the amount of standards work and industry effort that is being expended on a given topic is any indicator of the growing importance of a design concern, then power has most certainly become the hottest topic in the industry. Thankfully, it seems as if everyone has learned their lessons from the CPF/[gettech id="31044" t_name="UPF"] struggles and is attempting to coordinate activities, while ... » read more

Pushing The Performance Boundaries Of ARM Cortex-M Processors For Future Embedded Design
By Cadence - 08 Oct, 2014 - Comments: 0

One of the toughest challenges in the implementation of any processors is balancing the need for the highest performance with the conflicting demands for lowest possible power and area. Inevitably, there is a tradeoff between power, performance, and area (PPA). This paper examines two unique challenges for design automation methodologies in the new ARM Cortex-M processor: How to get maximum per... » read more

System-Aware SoC Power, Noise And Reliability Sign-off
By Ansys - 08 Oct, 2014 - Comments: 0

In globally competitive markets for mobile, consumer and automotive electronic systems, the critical success factors are power consumption, performance and reliability. To manage these conflicting requirements, design teams consider multiple options, including the use of advanced process technology nodes — especially FinFET-based devices. These advanced technology nodes allow chips to operate... » read more

Server Memory: Should We Be Concerned About The Power?
By Loren Shalinsky - 07 Aug, 2014 - Comments: 0

After my last blog post, Server Memory: What Drives its Growth, I had a couple of people ask me, “If server memory has increased by so much in the last four years, what effect has that had on the server memory subsystem power consumption?” It’s a good question. In last month’s blog, I calculated that the maximum memory per CPU has increased from 18GB (2010, highest-end Nehalem 45nm C... » read more

Designing For Security
By Ann Mutschler - 04 Aug, 2014 - Comments: 0

Some level of security is required in SoC today, whether it is in hardware, software or — most commonly — both. Of course, there is a price to pay from a power and performance perspective, but thankfully just a small one in most cases. The explosion of consumer devices has driven the need for increased security features in smart cards, smart phones, personal computers, home networks, and... » read more

The Power Of eDRAM
By Barry Pangrle - 16 Jun, 2014 - Comments: 1

In last month’s article we looked at different aspects of technology nodes and the multiple techniques that are used to keep scaling on its path of increasing density. From an energy standpoint, it’s expensive to move data around and with the high bandwidth that’s needed to keep processors “fed,” engineers are looking at ways to keep data closer to the processing logic and minimize th... » read more

New Uses For Emulation
By Ed Sperling - 16 Jun, 2014 - Comments: 1

Semiconductor Engineering sat down to discuss the changing emulation landscape with Jim Kenney, director of marketing for emulation at Mentor Graphics; Tom Borgstrom, director of the verification group at Synopsys; Frank Schirrmeister, group director of product marketing for the System Development Suite at Cadence; Gary Smith, chief analyst at Gary Smith EDA; and Lauro Rizzatti, a verification ... » read more

Do SoCs Need Earthquake Insurance?
By Ann Mutschler - 13 Jun, 2014 - Comments: 1

RTL sign-off is not a new term, but with SoCs that can be comprised of up to 90% IP blocks combined with the complexities that advanced manufacturing process nodes bring, RTL sign-off activities become a process that demands a more comprehensive approach. “There is a fundamental shift going on in chip design in general in that there is a bigger focus on so-called system on chip (SoC) desig... » read more
