Processor Subject To Change
By Ed Sperling - 09 Feb, 2012 - Comments: 0

By Ann Steffora Mutschler With power complexity driving sophisticated management techniques, SoC design engineering teams are turning to a new class of customizable processor architectures from ARM, CEVA, NVIDIA, Qualcomm and Tensilica and others to take advantage of the best in power saving techniques. While these new architectures are novel approaches, the concepts are not especially new,... » read more

Thinking Differently About Power
By Ed Sperling - 12 Jan, 2012 - Comments: 0

By Ed Sperling Battery life and lower electricity bills are now marketing tools for makers of SoCs, the mobile devices they go into, and servers that power data centers. A smart phone battery that lasts through the day without a charge, even when the user is playing high-action games, is a lot more attractive than one lasting only a few hours. And a data center electricity bill that shows a sh... » read more

Innovation At The Core
By Barry Pangrle - 03 Nov, 2011 - Comments: 0

By Barry Pangrle A number of next-generation ARM-based multi-core systems are starting to show up in the press. Nvidia has released information on its upcoming Tegra 3 (also known as “Kal El”). At last week’s ARM Techcon in Santa Clara, ARM gave several presentations around its Cortex-A7 (Kingfisher) and Cortex-A15 (Eagle) architectures and collectively about its big.LITTLE strategy. Qua... » read more

Tech Talk: Graphic Headaches

Let The Mobile Games Begin

By Pallab Chatterjee Mobile devices today are optimized for low- to mid-bandwidth data transmission, which is sufficient for e-mail, batch downloads of applications and music, and playback of encoded/compressed streaming video. But in coming months they will add another feature—image capture and processing and advanced graphics processing. This adds a whole new wrinkle to mobile devices, ... » read more

The Missing Pieces In Power Modeling—And Who’s Going To Provide Them
By Ed Sperling - 10 Feb, 2011 - Comments: 0

By Ed Sperling The push to develop power models is growing at each node, and at 22nm it will be virtually impossible to proceed without one or more models for power. Providing these kind of models is easier said than done, however. Creating an accurate power model requires accurate data from all the other pieces on a chip that potentially can affect the power. That includes how third-party ... » read more

From Multicore To Many-Core
By Ed Sperling - 23 Sep, 2010 - Comments: 0

By Ed Sperling Future SoCs will move from multiple cores—typically two to four in a high-power processor—to dozens of cores. But answers are only beginning to emerge as to where and how those cores will be deployed and how they will be accessed. Just as Moore’s Law forced a move to multicore architectures inside a single processor because of leakage at higher frequencies, it will begi... » read more

Diverging Worlds
By Ed Sperling - 23 Sep, 2010 - Comments: 0

The big surprise at the GPU Technology Conference this year, spearheaded by Nvidia, isn’t that GPUs are getting faster or that they can do amazing things. It’s that so little attention has been paid to the volume platforms that people carry around in their pockets. What has always been interesting about GPUs is they are the one platform where software can be truly parallelized and accele... » read more

Storm Before The Calm
By Ed Sperling - 17 Sep, 2010 - Comments: 0

The announcements out of ARM and Intel over the past couple week—and presumably from rivals AMD, MIPS and even Nvidia in coming weeks—are more than just a struggle for one-upmanship. The goal is much more far-reaching and the stakes are significantly higher than who has the fastest processor or core or even the lowest-power version. In the past year there has been a massive push to expan... » read more

Power Or Performance?
By Ed Sperling - 10 Jun, 2010 - Comments: 0

By Pallab Chatterjee Most microprocessors have shifted to new small geometry processes in order to be the most efficient at power and high performance. However there is always a trade-off between power, performance and area (PPA) for semiconductors, and this is especially relevant for processors. In the current design space, processors are created as general-purpose products, but they are gene... » read more
