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