Editor's Note
There's been a very definite upbeat tone this week at ARM Techcon in Santa Clara, Ca., including a report that new licensees will give ARM a strong Q3. This optimism is reflected in the many ARM related news and product introductions: Express Logic's ThreadX/SMP RTOS for ARM's MPcor e , Avnet's new online ARM embedded software store, Atmel sampling a Cortex-M4 flash MCU, Freescale integrating ARM Cortex-M4/A5 cores, HP readying ARM based servers , and IAR's ARM Cortex Workbench enhancements, . To see what the future holds be sure to read Dylan McGrath's interview with the lead designer on the Cortex-A7 core .
In addition to a range of design articles on Embedded.com on topics such as processor safety strategies, low energy MCU development, motor control power management, there are a number of ARM related features that are my Editor's Top Picks , including:
ARM Cortex-A-15/A-7 Big.Little processing
The basics of Cortex-M0 low power programming
How to adapt traditional RTOSes to SMP
And for some things totally different, be sure to check out Jack Ganssle's “Puddle of Gates,” and “Android at ESC and IDF ” by Chris Ciufo, as well as Part 2 in Jack Crenshaw's “Estimation Interruptus .”

The basics of low power programming on the Cortex-M0
In this article, Joseph Yiu, author of “The Definitive Guide to the Arm Cortex-M0,” provides a brief introduction to some of the ways in which a programmer can take advantage of the processors low power features.
Basics of porting C-code to and between ARM CPUs: ARM7TDMI and Cortex-M0
In this three part series, Joseph Yiu, author of “The definitive guide to the ARM Cortex-M0,” provides some basic guidelines for porting your code base from other 8/16 bit MCUs to ARM and between various ARM processors. Part 1: ARM 7TDMI and Cortex-M0.
How to adapt traditional RTOSes to symmetric multiprocessing
Developers of software and RTOSes for the multicore designs in many communications and consumer apps do not need to abandon the well-understood symmetric multiprocessing model.
Big.LITTLE processing with ARM Cortex-A15 & Cortex-A7
This paper presents the rationale and design behind the first big.LITTLE system from ARM based on the high-performance Cortex-A15 processor, the energy efficient Cortex-A7 processor, the coherent CCI-400 interconnect and supporting IP.
Integrated tools streamline low-energy MCU development
Microcontroller development is a complex process. Each individual model is different, with its own set of interfaces and control registers. Low-energy MCUs extend the range of options with a variety of power-down modes and in some cases intelligent I/O engines to offload some of the processing burden from the processor core.
Matching processor safety strategies to your system design
The right processor solution for the targeted safety-critical application can be different for every development team, even when designing the same type of end equipment.
Battery Charge Control: Dedicated ICs vs Microcontrollers
Microcontrollers can be used to directly control battery charger power conversion circuits. However, microcontroller circuits and firmware are normally more expensive to design and test and often cost more to produce than chargers based on dedicated charge control ICs. Here are the tradeoffs to consider when making a choice between microcontrollers and dedicated charge control ICs for battery charge control.
Real-time power management system for sensorless motor control and short circuit localization
The combination of power line communication and distributed computing offers a smart and low-cost solution for in-car subsystems power management.
