Changes (For The Better) In Muticore Technology
By Ed Sperling - 13 May, 2010 - Comments: 0

By Pallab Chatterjee Subtle but important changes are occurring in the multicore world, particularly in the power per function that is available from each core. Two trends are increasingly evident. First, there is a growing need for higher-bandwidth data transfer or multiple-function processing for existing data transfer levels. And second, there is a shift to low power or mobile implement... » read more

A Shock To The System
By Ed Sperling - 13 May, 2010 - Comments: 0

By Ed Sperling Electrostatic discharge used to be something confined to the I/O level, and often not even as part of the core design. But at 45nm and beyond, ESD is capable of wreaking havoc across a chip, blowing out transistors, wires and the insulation between them. What was once considered a sideshow in SoC development is becoming a central and critical issue at advanced nodes. The good... » read more

Making IP Tradeoffs For Power
By Ed Sperling - 13 May, 2010 - Comments: 0

By Ann Steffora Mutschler Power may be expensive, but just turning off sections of a chip, lowering the voltage or using low-power manufacturing processes have their own costs. Whether using power, or managing it, there is a price. As Brani Buric, executive vice president at Virage Logic says, “Power is not free.” But fortunately, other things in a design can be traded off in order to a... » read more

The Problem With Proximity
By Ed Sperling - 08 Apr, 2010 - Comments: 0

By Ed Sperling At 90nm companies had to begin thinking seriously about how the signals inside a chip would begin interfering with each other. At 40nm and beyond, they have to consider how signals are interfering with each other across an entire device that may include multiple SoCs. This marks an interesting shift in what companies have been calling holistic design for the better part of a ... » read more

Killer Bugs
By Ed Sperling - 08 Apr, 2010 - Comments: 0

By Ed Sperling Hardware and software bugs are all around us. When an application suddenly dies or a smart phone freezes because of the unanticipated interaction between hardware and software blocks in a system on chip, most users aren’t even the least bit fazed. They usually just re-boot and forget about it. Bugs caused by power are an entirely different matter, however. For one thing, ... » read more

The GaN Plan
By Ann Mutschler - 08 Apr, 2010 - Comments: 0

By Ann Steffora Mutschler Given the need to control power in high-end market segments such as servers, notebooks, mobile handsets and wired communications equipment, the market for gallium nitride (GaN)-based chips is poised for explosive growth. Case in point: Server farms are using more and more electricity, and the cost of that power is getting to be a significant fraction of the operati... » read more

Pricey Processes For Low Power
By Ed Sperling - 08 Apr, 2010 - Comments: 0

By Pallab Chatterjee Recently Samsung gave an update on the status and availability of its advanced 32/28nm process technology for use in foundry. The process is targeted for shipping designs to customers at the end of this year, with a road map that continues through the 22/20nm nodes and down to 15nm. What was particularly interesting were several key innovations that have made this all p... » read more

Grappling With Graphene
By Brian Fuller - 11 Mar, 2010 - Comments: 0

By Brian Fuller Silicon CMOS is a tough act to follow. The workhorse building block for the world’s electronics has been delivering for system designers for a half century. Despite hand-wringing over its apparent scalability limits, it shows only vague signs of slowing down. For nearly as many years, it seems, the next great material or alternative to silicon CMOS has popped into the indu... » 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

LTE Heightens Power-Consumption Concerns
By Ed Sperling - 11 Mar, 2010 - Comments: 0

By Ellen Konieczny The air interface dubbed Long Term Evolution (LTE) hails the coming of fourth-generation (4G) cellular communications, which will benefit from both increased capacity and speed. Among the lofty goals of 4G technology is the promise of users being able to widely access streaming media, such as mobile television and video, in real time. Before such capabilities can be made ava... » read more
