CES TSUNAMI/QUAD ARM/MULTICORE CHALLENGES/PUMPING SOFTWARE
The year in the embedded systems design is off to a fast start – maybebecause of the energy and resolve to keep all those New Year'sresolutions.

For example, at CES 2010 in Las Vegas, Nev., this week, animpressive collection of embedded consumer hardware and softwareintroductions are on display, including 3DTV, e-books, smartbooks, and wirelessvideo, a hybrid x86/ARMnotebook, an ARM based netbook and a dozen new 32 nanometer MPUs from Intel.

In other industry news, Marvell revealed a quad-core ARM processor,startups go after low power operation with asynchronous nulllogic, and Google is readying its Nexus One smartphone.

Even though we are coming off a long holiday, some of you camethrough with thought-provoking design articles that make me optimisticabout the year to come. For example, Spirent Communication's TomMcBeath details the design of a Linux, open sourceSQL network performance analysis test system and MindTree'sRajagopal Nagarajan provides a perceptive analysis of multicoretechnology and software tradeoffs .

I particularly enjoyed – and learned a lot from – two otherarticles: How to travelsafely in embedded code space and How to use adebugger as a bug preventive tool .” Other recommendedarticles include A new approach to improving systemperformance ,” and “Designing for performance with softwareoptimization.” Good reading!

Building a network performance analysis test system with Linux, Tcl/TK, SQL & extremeDB
Here's how a test system for network performance analysis and emulation of virtually any network traffic scenario was developed using a combination of the Linux OS, the Tcl/Tk scripting language, the eXtremeDB in-memory embedded database and an open source, SQL-based relational database.
  DESIGN FOCUS: Multicore Programming
Multicore technologies and software challenges
Multicore processors, which are basically processors with more than one core, are entering mainstream. Today, even desktops are having two or four cores and this trend is picking up and will only accelerate in coming years. This article looks at the drivers for the multicore, the challenges posed to the software community by the emergence of multicore technologies, the different options available in software and how the software community is likely to react to the challenges.
Optimizing Video Encoding using Threads and Parallelism: Part 1 – Threading a video codec
In this two part series on optimizing the design of an H.264 video encoder using threads and parallelism, the authors illustrate how multithreading based on the OpenMP programming model is a simple, yet effective way to exploit parallelism that only requires a few additional pragmas in the serial code. Up first: Threading a video codec.
