Too Many Standards, But Still Not Enough
By Ed Sperling - 15 Dec, 2011 - Comments: 0

By Ed Sperling The semiconductor industry has been one of the most prolific sectors in history when it comes to generating standards. Talk to any design engineer facing time-to-market pressures, new packaging approaches, and a mindboggling number of merchant IP, subsystems and interface requirements, and you’ll hear a compelling pitch for new standards. Talk to his or her boss and you’ll p... » read more

Power Changes Everything
By Ed Sperling - 14 Apr, 2011 - Comments: 0

By Ann Steffora Mutschler Optimizing design methodologies for effective power utilization sometimes meaning throwing out old ideas and approaches and starting fresh. This is exactly what wireless chip giant Broadcom did in its quest to manage power in its chips. Low-Power Engineering spoke with Michael Hurlston, vice president of the mobile wireless group at Broadcom, to discuss current and f... » read more

Keeping Up With Complexity
By Ed Sperling - 31 Mar, 2011 - Comments: 0

By Ed Sperling There are two schools of thought in designing complex SoCs. One says that increasing complexity requires a higher level of abstraction. The other says providing enough detail to get the design right is the only effective way to do it. There are staunch proponents of both approaches, but what has been missing are bridges to tie the higher level of abstraction to the more labo... » 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

Deep Dive: Energy Efficient Ethernet
By Ed Sperling - 04 Nov, 2010 - Comments: 0

By Pallab Chatterjee In late September, the IEEE ratified the 802.3az Energy Efficient Ethernet (EEE) specification. The standard, and associated test certification specification, was supported by co-development of over 20 commercial products from multiple vendors, of which 13 were release to market simultaneous with the ratification. Wael Diab, from the office of the CTO at Broadcom, and ... » read more

The Long And Painful Path To Power Optimization
By Ed Sperling - 11 Mar, 2010 - Comments: 0

By Ed Sperling Think about any mobile Internet device today. Batteries typically last all day, applications shut down with ease, and the number of things it can do has reached the point where many people typically carry one device on the road rather than multiple devices they used to lug around several years ago. Perhaps even more astounding is the price drop on these devices. A basic cell ... » read more

New Forces For Consolidation
By Ed Sperling - 05 Mar, 2010 - Comments: 0

For the past five-plus decades, the overriding effect of Moore’s Law was to put more circuits on a single piece of silicon. While that’s still the case, the addition of multiple cores since 90nm also has meant more functions can be added to that chip, which creates a whole new business equation for makers of complex devices like smart phones. Instead of creating individual chips, a single... » read more
