Redefining Performance In Mobile Devices
By Ed Sperling - 07 Oct, 2010 - Comments: 0

By Ann Steffora Mutschler While mobile product trends can be reliably unpredictable, devices are definitely moving towards supporting more software-based browsers, plug-ins for browsers, and downloaded codecs to go to browsers. This results in coming up with a best guess for performance targets. Throw power tradeoffs into the mix and things really start to get interesting. In terms of defin... » 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

Moving To Open-Source Software
By Ann Mutschler - 23 Sep, 2010 - Comments: 0

By Ann Steffora Mutschler With the typical cost of software accounting for 40% to 60% of an SoC, semiconductor OEMs are under more pressure than ever to meet margins. As a result, they are drawing on their ecosystem partners to provide a more complete foundation including hardware, software, FPGA prototypes, verification IP and virtual models, as well as an increasing demand for open source so... » 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

Changes In The Ecosystem
By Ed Sperling - 09 Sep, 2010 - Comments: 0

By Ed Sperling For the better part of two decades, semiconductor companies have been talking about ecosystems mostly for marketing and economic reasons. They’re now talking thinking about ecosystems for complex technology reasons that involve integrated models for power, transactions and manufacturability. In the late 1990s, IBM began assembling its own loose ecosystem as a way of shieldi... » read more

The Growing Software Challenge: From Stacks To SMP
By Ann Mutschler - 26 Aug, 2010 - Comments: 0

By Ann Steffora Mutschler Building a system now includes software, but defining the software stack is a mounting challenge for engineers. What used to be almost exclusively drivers now includes RTOSes and OSes, executable files, middleware, firmware, IP, embedded software and applications. With millions of different embedded products, all with different sets of software, it comes down to pr... » read more

New Low-Power Memory Interface Ahead
By Ed Sperling - 12 Aug, 2010 - Comments: 0

By Pallab Chatterjee The trend in consumer electronic devices is toward a multimedia-centric data flow, forcing changes in the memory interface needed to handle it. The increased compute resources needed for video signal processing, along with high-definition audio, used to be the exclusive domain of mainstream desktop computers and servers due to their access to memory and high data throug... » read more
