Getting a lot of buzz in the industry this week is a report on Freescale’s makeover given at Freescale Semiconductor’s annual Technology Forum, wherein CEO Rich Beyer committed the company’s future to embedded processing.

Other news from the meeting: Freescale rolled out AMP: Freescale’s answer to exploding Internet traffic, a MEMs-based barometric sensor for mobiles, and a family of smart auto MCUs . Also, Freescale revealed collaboration deals with Spansion on memory and Wind River on embedded tools.

On the design article side, in “Using drowsy cores to lower power in multicore SoCs ,” Freescale engineers describe a cascading memory management technique for multiprocessor designs. For more clever ideas from Freescale be sure to read “Energy efficiency may require a cool factor , ” about some of the possibilities discussed by a Smart Energy Panel at the Freescale meeting.

Not all the news this week is about Freescale: The U.S. House passed a patent reform bill , which will energize not only Freescale but most high tech companies by removing a major bottleneck to getting ideas to market in the United States.

Other must-read design articles this week include:

Using drowsy cores to lower power in multicore SoCs

Freescale engineers describe a cascading power management technique that steers tasks to a smaller number of cores during non-peak activity periods so that the idle cores can enter a minimal-power or “drowsy” state.

Reduce SoC device/package leakage/power with improved power management protocols

Described is a new power domain partitioning technique to reduced leakage in system-on-chip designs by taking advantage of package configuration information.

Managing power in embedded applications using dual operating systems

In this product how to article, TI's Loc Truong describes how to use inter-processor communication and state machine design to reduce the overall system power in a heterogeneous dual-core system.

The potential of energy harvesting means there's nothing to lose

Energy harvesting is rapidly maturing to become a key sector in the electronics industry, having risen over the past five years to take its place as a competent technology enabling an expanding market. While the pioneering companies behind the technology have faced many challenges in that time, the market now faces one of its biggest obstacles; convincing system integrators that it is a viable alternative to battery packs.

Debug a microcontroller-to-FPGA interface from the FPGA side

Microcontrollers and FPGAs often work together in embedded systems. As more functions move into the FPGA, however, debugging the interface between the two devices becomes more difficult. The traditional debugging approach comes from the microcontroller side, which relies on a serial-port printout. This approach adds overhead and may cause timing problems.

Model-based design passes muster for defense system

Model-based design continues to grow within the aerospace and defense industries. The development of aerospace and defense systems presents unique challenges. The first challenge is managing their extraordinary scale and complexity.
