Editor's Note

Bernard Cole Site Editor Embedded.com

A must-read this week for many embedded systems designers is Ron Wilson's article on “The puzzle of many cores.” In it he surveys the action at this year's Hot Chips Conference and has noted a trend away from relatively “simple” three and four core multiprocessor chip designs to configurations in the 10s, 20s and even 100s and he delves into the impact this will have on software development.

To get a better sense of what challenges embedded systems developers will be facing in the future as a result of these new hardware designs, I recommend reading the following reports on developments at Hot Chips:

ARM wrestles with silicon, battery hurdles
Tensilica DSP core does 100 GMACs at 1W
IBM plants transactional memory in CPU
Bits from Hot Chips: robots, Cisco, Oracle
Hot Chips probes latest microprocessors

These reports make it clear that embedded developers have significant challenges ahead. This means you have a lot of homework to do. In addition to Embedded.com and ESD Magazine , resources you can depend on are the Embedded Systems Conferences and the classes they offer. At the 2011 Fall ESC in Boston, Sept. 26-28 , for example, class tracks that should be helpful include:

Multicore Development
System integration and test
Networking and connectivity
Microcontrollers and SoCs
Prototyping Embedded Systems

However, if you want to distract yourself from the tough issues that Hot Chips reveals, be sure to read Jack Ganssle's tongue-in-cheek comments on all things mobile in : “What's all this cell phone stuff, anyway? “

Hot Chips: the puzzle of many cores

Papers at Hot Chips 2011 suggest that emphasis is shifting from multicore to manycore.

Hot Chips roundup

A roundup of stories from this years symposium.

Developing processor-compatible C-code for FPGA hardware acceleration

This article describes an iterative process for converting C code to run on FPGAs with or without processor cores, how to identify which code sections can best benefit from hardware acceleration, and coding styles to use to retain commonality.

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.

Understanding Smart Meters to Design Intelligent, Secure Systems

Keeping data secure is one of the major challenges facing both the utility companies and the e-meter vendors.

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.

Predicting thermal runaway – Part 1

Preventing thermal runaway requires balancing power dissipated by the device with power dissipated by the system.

Heat Removal with Microchannel Heat Sinks

Liquid-cooled microchannel heat sinks and coolers can be an effective way to remove high heat load from both chips and boards.

Implementing advanced control strategies for DC/DC converters using MCUs (Part 1 of 2)

Sub: Understand how a microcontroller can provide superior performance for phase-shifted, full-bridge DC/DC converters

Making embedded processing development easy – part 3

Steven Magee, software architect, embedded processing, Texas Instruments provides the answer to the question: ” I really would like to protect my software investment and re-use my code. What's the best way to do this?”

Data security in cloud computing – Part 4: Cloud data storage

Part 4 of an excerpt from the book “Securing the Cloud: Cloud Computer Security Techniques and Tactics” looks at the benefits of cloud-based data storage and concerns over cloud “lock-in.”

Integrate USB into image sensing applications

Integrating USB to existing image sensor design may immensely increase the value to the flourishing image sensor market segment. The addition of USB will increase device functionality while providing an additional method to control and upgrade devices in the field.
