Issue Highlights

Writing in software development

Constructors and object definitions

Ten million lines in 29 months: model-driven development on the Chevy Volt

Editor's Note

Bernard Cole Bernard Cole
Site Editor

Jack Ganssle augments his decades-long efforts toward safer, morereliable and more secure software code in his column this week,“Writing in software development”. This time his target is not badcode specifically, but bad writing in documentation by engineers andsoftware developers, which he believes is no more than grade schoollevel. “It’s ironic that engineers produce, more thananything, documents that are supposed to communicate ideas, yetwe’re so poor at written communication,” says Jack in hiscolumn, where he outlines some possible remedies.

Jack will be teaching several courses on software development atthe Spring 2011 ESC May 2-4 , where this and a number of softwarequality topics will be discussed. Also Embedded.com columnist DanSaks will be teaching several classes on C and C++ programming. Hiscolumn this month is on “Constructors and object definitions.”Several ESC class tracks on the ever important topic of code qualityinclude: Programming languages and techniques, Best Practices, andDebugging and Optimizing.

Two stories of special interest in this issue:
Calucccino programmer’s calculator for iPhone, by Embedded.comProducts Editor Toni McConnel, on a unique new IPhone app that doesprogramming, engineering, and scientific functions.

I’m flipped out about Cisco,” by Mark LaPedus on his reaction tothe news that Cisco Systems has stopped production on the Flip videorecorder.

Important note: Starting April 18, the Embedded.comnewsletters will arrive in your mailbox about 10 -12 hourslater. Depending on where you are on the globe, you can expectto see them in your email on Mondays and Thursdays.

Design How Tos

M-PHY benefits and challenges

As the M-PHY begins to enjoy wide adoption rate in many applications, Mixel's Ashraf Takla and ST-Ercisson's Cedric Berholom review some of its benefits and challenges.

How to design next-generation RF remote controls

If you are looking for an explanation of all the flavors of ZigBee and how RF4CE plays in this area, this article if for you.

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.

Trip over threads to trap multicore bugs

Here is how developers of concurrent programs can find software bugs caused by intermittent failures, non-deterministic behavior and asynchronous events and reproduce them in a controlled environment using a new X86 Linux platform development tool.

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.

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.

Is lock-free programming practical for multicore?

In a multicore environment, you can do resource sharing efficiently without locks, but there are some caveats.

Dealing with the minutiae of fingerprint analysis

Fingerprint analysis involves using fingerprint sensors and sophisticated DSP-based image-processing algorithms. Here's a description of the minutiae-based system for fingerprint analysis.

The purpose-driven CPU: Multiple tasks in Carrier Ethernet

Service providers know that some functions offered by network equipment providers will be upgraded in silicon. The strategy followed by a semiconductor provider of distributing network intelligence and making devices in an Ethernet portfolio ready for advanced services, allows for future-proof network nodes from switch-routers to backhaul equipment.

8-bit MCUs provide cost effective, efficient high-brightness LED control

High-brightness LEDs are rapidly gaining popularity in the automotive, consumer, and industrial markets. But controlling luminosity efficiently and reliably is not an easy task—power stage efficiency, thermal design, and EMC are some of the most critical design challenges.

Using high-density programmable FIFOs in video and imaging applications

Many market segments, including video broadcasting, military, medical imaging, and base stations, can benefit from the use of high-density FIFO solutions that have programmable features.

Using verification coverage with formal analysis

This article looks at what “coverage” means for formal verification tools, and how formal coverage fits into metric-driven verification flows. It discusses formal coverage in terms of three questions: how good are my formal constraints, how good is my proof, and how can I feel confident my verification is complete?

It's less than a month now until ESC Silicon Valley 2011 at the McEnery Convention Center in San Jose, California and we are
getting fired up about all the great hands-on educational opportunities.
We are especially excited about the just-announced Beer and Boards training available for All Access pass holders!
Pick one of the development kits to take home:
