Experts At The Table: Low-Power Verification


By Ed Sperling Low-Power/High-Performance Engineering sat down to discuss power format changes with Sushma Hoonavera-Prasad, design engineer in Broadcom’s mobile platform group; John Biggs, consultant engineer for R&D and co-founder of ARM; Erich Marschner, product marketing manager at Mentor Graphics; Qi Wang, technical marketing group director at Cadence; and Jeffrey Lee, corporate app... » read more

Too Big To Handle?


By Ann Steffora Mutschler With the insatiable demand for power efficiency today, the power management tasks have been pushed up into the realm of the software engineer due to the sheer complexity of the hardware design and the demands on the hardware designer to get their part right. Managing power properly in embedded software boils down to really understanding the application and how it i... » read more

Experts At The Table: Performance Analysis


By Ed Sperling Low-Power/High-Performance Engineering sat down with Ravi Kalyanaraman, senior verification manager for the digital entertainment business unit at Marvell; William Orme, strategic marketing manager for ARM’s System IP and Processor Division; Steve Brown, product marketing and business development director for the systems and software group at Cadence; Johannes Stahl director o... » read more

A Tale Of Two Standards


By Ed Sperling It could well be one of the strangest developments in standards history. Two competing standards for power formats were rolled out in the middle of the last decade and aside from a few cries of foul they fell below the radar screen of most chip designers and architects for a half-dozen years. Fast forward to the present and the Common Power Format (CPF) and Unified Power Form... » read more

Trading Off Power And Performance


By Ann Steffora Mutschler There is no shortage of opinions when it comes to the topic of performance and power tradeoffs. From abstracting the task from engineers to process considerations, engineering teams have a number of tools and approaches at their disposal to make the optimal design choices for their application. Take the MCU application space for instance. Ken Dwyer, director of app... » read more

Software Debug Gets Tricky


By Ann Steffora Mutschler As designs continue to grow in size and complexity, that complexity has led to an increasing number of processing cores. Additional cores, in turn, allow for additional software to be run on those cores, and debugging the software becomes critical. Traditionally, emulation has played a significant role in verifying that software against RTL code, and continues to d... » read more

Dealing With New Bottlenecks


By Ed Sperling While the number of options for improving efficiency and performance in designs continues to increase, the number of challenges in getting chips at advanced process nodes out the door is increasing, too. Thinner wires, routing congestion, more power domains, IP integration and lithography issues are conspiring to make design much more difficult than in the past. So why aren�... » read more

The Controversial Spec


By Ann Steffora Mutschler Design sophistication and complexity has made it increasingly difficult to fully specify the expected behavior of a block in an SoC, but this is necessary for design and verification teams. How do you write a “good” and “complete” specification of functionality? It turns out that the discussion of defining what a good and complete specification is and how t... » read more

New Approaches To Better Performance And Lower Power


By Ed Sperling Until 90nm, every feature shrink and rev of Moore’s Law included a side benefit of better power and performance. After that, improvements involved everything from different back-end processes to copper interconnects and transistor structures. But from 20nm onward, the future will rest with a combination of new materials, new architectures and new packaging approaches—and som... » read more

Rethinking Big Iron


By Ann Steffora Mutschler One size does not fit all when it comes to the server market, and that may be the best option for low-power processor makers to gain a toehold in a world that until now has been almost laser-focused on performance. Even higher-performance versions of low-power processing architectures are starting to show up inside of datacenters. Many are application-specific ... » read more
