This week I was glad to be distracted by the news that Google is buying out Motorola Mobility for $12.5 billion. Reading various analyses of what the bid will mean took my attention away from the unsettling economic news. For example, yet another electronics firm – Analog Devices – is reporting bad financial results, In China, which up ‘til now had seemed relatively immune to the economic turmoil, mainland Chinese chip foundrySMIC is preparing for a long downturn.

Fortunately, there is other distracting news to keep our minds directed elsewhere. For one thing, Microsoft revealed plans for Windows 8, which it claims will be the biggest redesign since Window 95, and a there’s a flood of new processors out of the Hot Chips Forum.

Over the next few weeks leading up to the Fall Embedded Systems Conference Sept. 26-29 in Boston, we will be providing further distractions by reporting on upcoming events at what Nic Mokhoff describes as a “rich tech carnival.” To learn more, there is a round up of news about the conference at EETimes' Advance Coverage of ESC Boston.

To further distract you, we have design articles this week on topics that include: energy efficient Ethernet, Wind River’s take on the MILS architecture , and making embedded processing easier. My Editor’s Top Picks are:

Software forensics for embedded systems developers
Basics of core-based FPGA design
PCIe & intelligent DMA in high data rate recorders

Be sure to read Embedded cyber-risks ” from Jack Ganssle, in which he ponders the impact of a dismayingly ill-informed and naïve report on cyber-security that the U.S. Department of Homeland Security presented before Congress.

Basics of core-based FPGA design: Part 1 – core types & trade-offs

In Part 1 in this four part series, the authors of “Rapid System Prototyping with FPGAs,” provide an overview of FPGA processor core types – firm, hard and soft – and the pros and cons that need to be evaluated in the context of an embedded system's requirements.

Software forensics for embedded systems developers

In this chapter from his book “The Software IP Detective's Handbook,” Bob Zeidman describes some of the concepts behind the new field of software forensics, and how they can be used to safeguard the unique and proprietary Intellectual Property incorporated into your design.

Using PCIe & intelligent DMA to achieve blazing data rates in real-time recording instruments

How the use of PCIe, intelligent DMA and a real-time analog-to-digital front end as well as an efficient API messaging structure resulted in a data recorder capable of sustained data to disk rates of 2 GB/sec and higher.

e-MMC vs. NAND with built-in ECC

Ultimately, if your processor can support both e-MMC and MLC NAND with ECC, which should you choose? A look at the attributes, benefits and situational advantages of each

Optimize Energy Efficient Ethernet (IEEE 802.3az) performance in bundled links

Here is a technique that optimizes the use of Energy Efficient Ethernet in bundled links that improves responsiveness, and minimizes frame delay and loss. It can also be implemented by each link endpoint independently for easy deployment.

MILS architecture simplifies design of high assurance systems – Part 1

The Multiple independent levels of security (MILS) architecture provides a framework for development and validation of secure operating systems for military and avionics applications.

Cache-Coherence Verification

Cache coherency structures present complex problems for verification, and must be approached systematically.

Get control of ARM system cache coherency with ACE verification

In this Product How-Two article, the Cadence authors describe how to use the company's Verification IP solutions framework to implement ARM's AMBA 4 Coherency Extensions (ACE) in embedded SoCs

Making embedded processing development easy – part 2

We're on the second installment in a sequence created to introduce you to the fundamentals of embedded software design and considerations to aid with embedded processor design.

Resistors advance diverse medical diagnostic and therapeutic capabilities

This “lowly” passive component is critical to medical instrumentation circuitry

SIGNAL CHAIN BASICS #56: Clock Jitter Demystified—Random Jitter and Phase Noise

Understand some key parameters of this critical specification, which affects many aspects of the signal chain

Use LED lighting to improve user interfaces in appliances

LEDs, both low-power indicators as well as high-power Lights, can enable an advanced User Interface as well as a high-end look-and-feel for today's smart appliances.
