Case Study: A Better Way To Predict Weather


By Ed Sperling Most of our weather predictions are developed from about 150 stationary government radar systems, which interlock and occasionally overlap to create a cohesive picture. The picture isn’t perfect—in fact, it’s probably the equivalent of looking at a large, grainy satellite photo—which creates plenty of wrong forecasts. But the system can track large storms across state bo... » read more

Can SaaS Really Make Chip Design Easier?


By Cheryl Ajluni Software as a Service (SaaS) is not a technology. It is a software deployment business model where an application is hosted as a service that is provided to customers across the Internet. Thanks to success stories from companies like Google, Salesforce.com, WebEx, and TurboTax, among others, this business model has become quite popular and is now even being looked at by some E... » read more

Houston…We Have A System-Level Problem


[youtube vid=iZ61OU12TNU] Just imagine what happens when the guidance system on the International Space Station goes on the fritz and the entire lab begins doing somersaults through outer space. Then the solar panels no longer work and the communication system fails, and suddenly you understand how serious system-level design problems can become. Ret. Capt. Daniel Bursch recounts the inciden... » read more

SOI Goes Mainstream


By Ed Sperling The crossover for system on insulator (SOI) versus bulk CMOS was supposed to happen at the 22nm, but that was before software developers ran into problems programming multicore chips. For years, SOI was considered the high-performance cousin of CMOS—more expensive, more difficult to manufacture and unnecessary for most applications. It is the heart of the Cell processor, ... » read more

Better Ways to Connect IP


By Ed Sperling Re-usable intellectual property may sound great on paper, but actually getting pieces to be as interchangeable as Lego parts and automatically configuring them to work in a system on a chip requires more than technology. It requires a leap of faith on the part of chip engineers, and that doesn’t happen overnight. The first step toward providing the tools was creation of the ... » read more

Things You Never Knew About System Verilog


System Verilog is considered the current standard for a combined hardware description and verification language, and has been welcomed with open arms since it was approved by IEEE in 2005. Its usefulness in designing and verifying new chips is well known among those who work with it. The only problem is that many engineers still don’t know how to use more than a fraction of its capabilities�... » read more

Multicore Programming: The Next Frontier?


By Ed Sperling From a distance it looks like a game of hot potato. But this version is played by hardware and software engineers, who normally don’t have much to do with each other. The hardware engineers say you can’t get any more performance out of a single core on a chip without cooking it, so they’ve added more cores and tossed the problem over the wall to the software e... » read more

Cross-Talking with TLM 2.0


By Ed Sperling It’s almost like flying over the Great Plains of the United States. On the ground it’s hard to see above the corn stalks, but in an airplane you can see the entire horizon even if you can’t see those stalks anymore. The analogy is similar to where most of the major players in chip design say the engineering for systems on chips needs to go. With millions more gates avai... » read more

Object-Oriented Programming Is Back


Object-oriented programming is finally starting to look promising. For anyone who’s been following this technology, a statement like that is enough to evoke loud groans. Object-oriented programming, a.k.a. OOP, was first developed in the early 1960s. The goal was, and still is, to re-use components in software development—almost like Legos—by raising the level of abstraction for progra... » read more
