The rising popularity of open source Linux for desktop and server computing is well documented, but in the electronics space the mobile implementation of Linux is gaining increasing attention.
With ever more functionality being added to smartphones, the convergence of voice and data, and the use of 3G comms becoming more pervasive, the opportunities for handset manufacturers are increasing. An important part of this landscape is mobile Linux. It is a subset of the open source software that specifically targets ultra-portable devices, with the design and resource constraints this target platform implies.
In the following, to help cover this important electronics industry trend, we bring together all the mobile Linux-related resources from Electronics Weekly and the wider Web.

ELECTRONICS WEEKLY ANALYSIS RELATED TO MOBILE LINUX
How to move from legacy OS to Linux in easy stages
Embedded Linux is rapidly encroaching upon application spaces once considered the exclusive domain of embedded kernels such as VxWorks, pSOS and in-house platforms. Industry analysts show embedded Linux and open source garnering up to one-third of 32 and 64-bit designs, more than twice the share of any other embedded OS.
Analysis: Embracing open source GPLv3 and avoiding hardware lock-in
It is almost a year since the Free Software Foundation (FSF) released the third version of its General Public License (GPL). Prior to the release there was a great deal of public consultation where several contentious issues were hammered out. The greatest of those was the Tivoisation clause.
Analysis: Linux versus RTOS
Hans-Jürgen Rauscher, System Architect at Wind River, compares the real-time capabilities of Linux and a real-time operating system.
Mobile operators increase network efficiencies
The availability of data services is being eyed by mobile operators as a key way to increase user revenue. The problem is today’s mobile networks are all about voice services, with only a small proportion of users – roughly ten per cent in developed areas, less in developing markets – using any data capability at all other than text messages to mobile phones.
Mobiles to get stereophonic sound
Stereophonic sound is usually only achievable when speakers are physically separated from each other by a considerable distance. When speakers are situated closer together in mobile phones it is possible to simulate stereo by using wave interference to cancel the left channel sounds in the vicinity of the listener’s right ear, and vice versa.
Reducing power consumption in battery powered applications
Automotive-electronics content is expanding at an ever-increasing pace. Today, an average car has 25 to 35 microcontrollers; approximately half of those are 8-bit units. High-end vehicles can easily have 80 or more microcontrollers.
