More Cores, Different Approaches
By Ed Sperling - 27 Aug, 2009 - Comments: 0

By Ed Sperling The general consensus among software developers is that some applications will never be able to take advantage of multiple cores, but that certainly doesn’t mean system designers can’t figure out ways to use more cores. Nor does it mean that all cores are created equal. The picture that is emerging from multiple chipmakers shows the following trends: More cores have lim... » read more

Hot Chips 2009: It’s All About Multicore And Low-Power
By Pallab Chatterjee - 27 Aug, 2009 - Comments: 0

By Pallab Chatterjee The game has changed for processors. The goal now is data throughput, not higher gigahertz and more watts. That shift dominated the presentations at the Hot Chips conference this week. In previous years, the theme was higher single-core performance, more power and smaller geometries processes. This year it was all about multi-core and multi-power options as the realities ... » read more

Writing Software For Low-Power Systems
By Ed Sperling - 15 Apr, 2009 - Comments: 0

By Ed Sperling Almost any discussion of software in low power systems these days involves some sort of multicore approach. That is particularly true at 90nm and below. At 65nm, unless there is a very distinct purpose for a low-power single-core device, it probably is utilizing at least two cores, and at 45nm the numbers can continue to rise, depending upon how many functions the chip is being... » read more

Taming The Multicore Beast
By Ed Sperling - 27 Mar, 2009 - Comments: 0

By Ed Sperling Multicore chips are here to stay. Now what? That question is echoing up and down the ranks of tools vendors, design engineers, software developers and even among people who measure the performance and efficiency of semiconductors. There is now a Multicore Expo and a Multicore Association that includes a who’s who of electronics. And there are lots of working groups developing... » read more

NoC Your SoCs Off
By Ed Sperling - 19 Feb, 2009 - Comments: 0

By Ed Sperling The network on a chip (NoC) approach is gaining ground as an essential part of a system on a chip (SoC), providing the same kind of time-to-market advantage that well-tested intellectual property blocks provide. This follows almost eight years of hype about NoCs potential with little to show for it. Times have changed and there appear to be two main drivers, one technological a... » read more

The Great Debate: Fewer Functions?
By Ed Sperling - 19 Feb, 2009 - Comments: 0

By Ed Sperling What do you do when you can’t fit any more functionality on a chip without blowing your power budget? That question is being debated inside IBM right now, and one of the more radical concepts is to actually have systems do fewer things. “That trend will happen,” said Brad McCredie, chief architect of the Power6 chip and an IBM Fellow. “I think devices w... » read more

The Trouble With Multicore Software

David Patterson, Professor of Computer Science at UC Berkeley, presented his views to the Naval Postgraduate School about the prospects for multicore programming success. This video was excerpted from his presentation. [youtube vid=EDHXIH8DlLY] » read more

Making A Multicore System Work
By Ed Sperling - 05 Feb, 2009 - Comments: 0

Making all the pieces work together in a multicore system requires a deep understanding of the technology, lots of different layers of synthesis, and some incredibly complex testing strategies.   System-Level Design sat down with James Aldis, system on chip architect for Texas Instruments wireless business unit; Charles Janac, president and CEO of Arteris, Drew Wingard, CTO of Sonics, and ... » read more

Making A Multicore System Work
By Ed Sperling - 29 Jan, 2009 - Comments: 0

If you think designing a single-core system is hard, designing multicore systems is multiple times harder. Connecting all the pieces together and making them work properly, if not together, is one of the hardest tasks design engineers and architects will ever face. System-Level Design tracked down some of the experts in this field and sat them down around a table to discuss what’s going... » read more
