According to Embedded Editorial Director Colin Holland, the best way to think about the new DESIGN West 2012 , beginning this week in San Jose, is as if it were ESC on steroids . In three intense days of courses, panel sessions, keynotes, hands-on tutorials and myriad show floor activities, in addition to the Embedded Systems Conference , the expanded venue also includes targeted DESIGN West Summits on Multicore Development, Sensors , Medical Systems, LEDs , Android, and Security .

In addition to more than 150 classes, there are several must-attend keynote addresses, Android certification classes, and more than 250 exhibitors. There also will be sponsored training classes from companies such as Arm, Freescale, Intel, Microchip, Mouser and Texas Instruments, and several build-your-own embedded system classes.

If you are not able to attend (or you are attending and want more immersion ), included here are recent design articles, Webinars, online tutorials, and white papers based on past ESC classes. Of these, my Editor's Top Picks are:

Troubleshooting real-time software issues using a logic analyze r

Agile embedded software development
Using trace to solve the multicore system debug problem
Non-intrusive multicore debug & performance optimization

While the focus of all the DESIGN West Summits is on the continuing education of current working embedded systems designers, attention is also given this week to inspiring and educating future engineers in a meeting of concerned developers and a panel session on the topic. Also, on a related topic, be sure to read “The education of embedded systems software engineers ,” by Robert Dewar of Adacore (Booth #2319 ) on his concerns about the training of engineers in U.S. universities.


Design How-Tos

A survey of Linux device drivers

Embedded Consultant Bill Gatfiff provides an tutorial overview of many of the different types of device abstractions available under Linux, with sample source code, taken from an ARM-Linux-2.6.12 kernel.

Agile embedded software development

Developers flee engineering for marketing and management. Why? Big processes are not delivering, and neither is coding chaos. This author says Agile helps address the problems of late projects, high defect levels, and stressed teams.

Adopting C programming conventions

This ESC paper discusses some common problems found in a lot of code and suggests strategies for avoiding them.

Porting an existing embedded system to Linux

Designers from Intellibot Robotics chronicle the transformation of their microcontroller-based embedded design ” a mobile robot – from one without an OS to one built on Linux, describing issues relating to debugging, real-time performance, the use of the GCC tool chain and multithreading using POSIX..

uClinux on the Blackfin DSP Architecture: Part 1

In this first in a three part series, the author provides an overview of the benefits and challenges of using DSP-based architectures with uClinux.

Using trace to solve the multicore system debug problem

In this article, Aaron Spear of VMware outlines current multicore development trends, explores the deficiencies in traditional software development tooling when applied to multicore systems, introducing the “Common Trace Format” (CTF), a coming standard for tracing multi-core systems over time.

Real-Time Kernels in medical device development (ESC-214)

Micrium's Matt Gordon provides an introduction to real-time kernels with a particular focus on what embedded developers of medical devices will need to know to begin writing multi-task applications.

Beyond MakeFles – Building large-scale C projects (ESC-200)

In this article, Mike Shal, who is teaching a class (ESC-200) at ESC Boston, takes you through the history and processes involved in building C-language make files and discusses why “make” fails its basic promise and what you can do about it.

Troubleshooting real-time software issues using a logic analyzer

This logic analyzer technique is a power-tool for the embedded software engineer's toolbox.

Interrupt Management Under Linux: Using the Interrupt Controller API

Bill Gatliff provides a walkthrough of the portions of the Linux kernel that manage interrupts and describes how Linux interacts with interrupt controllers and how to adapt code for custom hardware.

Non-intrusive debug and performance optimization for multicore systems

While efficiently partitioned and bug-free software on multiple cores is crucial for taking full advantage of their power, debugging of such systems adds more complexity due to vanishing accessibility of the sub-system interfaces, buses and concurrency, requiring the use of advanced system trace technology.

Analyzing multithreaded applications—Identifying performance bottlenecks on multicore systems

Here's a step by step method for identifying and analyzing bottlenecks in multithreaded applications on multicore systems.
