Tuning Heterogeneous SoCs


It's one thing to pack multiple processor cores into a design, but it is much more difficult to ensure the hardware matches the software's requirements, or that the software optimally uses the hardware. Both the hardware and software teams are now facing these issues, and there are few tools to help them fully understand the problems or to provide solutions. Design teams continue to add more... » read more

The Week In Review: IoT


Management Intel has hired Tom Lantzsch, the executive vice president of strategy at ARM Holdings, to serve as senior vice president and general manager of its IoT Group, effective in January. Lantzsch succeeds Douglas Davis, a senior vice president who was running the IoT Group and had announced plans to retire from Intel after more than 30 years. Davis reconsidered that move, however; he wil... » read more

Partitioning For Power


Examine any smartphone design today and most of the electronic circuitry is "off" most of the time. And regardless of how many processor cores are available, it's rare to use more than a couple of those cores at any point in time. The emphasis is shifting, though, as the mobility market flattens and other markets such as driver-assisted vehicles and IoT begin gaining traction. In a car, turn... » read more

Metrics For Measuring Performance And Power In IoT SoC Designs


The problem confronting chip designers developing IoT SoCs is the need for high compute performance and low power consumption. This is especially true for SoCs being developed for devices required to operate for years on a battery. One example is the new generation of electronic shelf label (ESL) with a requirement of five years. The ESL receives central server pricing updates along with a f... » read more

More Cores, Different Approaches


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
