We all know developingfor embedded systems is a tough job, and it's getting tougher all thetime, as evidenced by the calls for higher quality at all levels ofelectronics design in the wake of the Toyotarecall .

In The Non-qualityrevolution, Jack Ganssle reiterates the importance of aconstant focus on improving software quality and points out that “if a nation(or perhaps even a company) starts a software quality revolution, likeJapan, they will corner the market for their products .”

If you are serious aboutgetting your company more involved in improving software quality, agood place to start is the three partseries from Jack Ganssle on Getting disciplinedabout embedded software development .”

Also, inPreventing dynamicallocation ,” Dan Saks describes a simple technique forwarning about unwanted dynamic allocation in C/C++ code. And becausethe ARM architecture is so ubiquitous in embedded designs, anothermust-read is Decompiling the ARMarchitecture code .”

Of course, software is notthe only place where attention to high quality is crucial. Here aresome more articles this week related to quality worth reading,including: enhancing MCUperformance with DMA , ICE debugging,designingenergy efficient systems, dodging Amdahl's Lawwith FPGAs, and improvingthe thermal integrity of IC packaging and board design. Goodreading! (Embedded.com Editor BernardCole, bccole@acm.org )

P.S. – The deadlineto submit abstracts for ESC Boston is upon us. You have untilMonday, March 15, 2010 to submit an abstract for the technical programat the Embedded Systems Conference Boston, September 20-23. Here's the link to see the tracks and submit anabstract.

 EDITOR'S TOP PICK by Bernard Cole, Embedded.com Editor
Enhancing MCU performancewith a DMA-based event system controller
This article describes the processing bottlenecks of currentmicrocontroller architectures and explore how to achieve higherprocessing efficiency by offloading the CPU via coprocessors,accelerating memory access using multi-channel DMA, and eliminatinghigh-speed peripheral and I/O bottlenecks through an integrated eventmanagement system.
Decompiling the ARMarchitecture code
At UBM TechInsights we are often tasked with proving patentinfringement of a software algorithm as part of our IP ManagementServices. Our example algorithm is based on the ARM architecture.
 DESIGN FOCUS: Managing Software Design
Getting disciplined aboutembedded software development
Here's a three part series from Jack Ganssle on doing softwaredevelopment in a disciplined way to reduce both errors and the time ittakes to complete a project. 
 DESIGN ARTICLES: Week of March 8-12
ICE debugging: The end ofthe battleship game
Lauro Rizzatti at EVE-USA explains why the “Battleship Game” remindshim of trying to debug a system-on-chip (SoC) design using thein-circuit-emulation (ICE) mode.
Designing high-tempelectronics for auto and other apps
High-temperature semiconductor technologies can survive temperaturesapproaching 400°C, but careful design of the product is required todeliver cost-effective devices achieving stable, predictableperformance.
Designing intelligent smartgrid systems that promote energy efficiency
Low-power analog, mixed-signal, and RF building blocks are needed totransform the power-grid plans into reality
Dodging Amdahl's Law withmessage passing, FPGA-based, parallel processing
Most design teams agree that the basic plumbing of memory managementcan be the real bottleneck in heterogeneous processing. Today the onlyreal solution is the microprocessor and co-processors sharing memory onthe node, and then interconnecting many nodes with a GigE, Infiniband,or a custom interconnect configuring the nodes in a distributed memorylayout.
Ensuring the thermalintegrity of your IC package/PC board design
Some basic tests will verify your PCB/IC thermal modeling and reality
