3G Linux

Working in with Purple Labs, in 2007 NXP launched the Nexperia cellular system solution 7210 with Linux for 3G handsets. Not having the additional cost and complexity of integrating a dedicated application processor, manufacturers were able to use a high level operating system. Operators were also be able to provide a stable and powerfu platform to offer new connected services. The system was a powerful dual-mode UMTS multimedia platform running on a single-core ARM9 for the 3G mobile feature-phone market. By offering a Linux-based platform on a single core, the platform allowed easy development and upgrades. The 3G Linux environment supports UMTS performance, delivering seamless service coverage in 2G and 3G networks as well as an advanced level of multimedia features that allow to take full advantage of 3G. The Linux software suite runs on top of a Linux 2.6 kernel.

Linux 2.6 kernel

The Linux 2.6 kernel, released in December 2003, represented a significant step forward in the evolution of the Linux operating system. It introduced major changes aimed at improving performance, scalability, and feature set. Some of the prominent features of the 2.6 kernel include improved support for symmetric multiprocessing (SMP) and threading, which increased the efficiency of Linux on multi-core systems. It also added support for Non-Uniform Memory Access (NUMA), beneficial for systems with multiple processors. The 2.6 kernel series saw the introduction of udev, a device manager that dynamically creates or removes device node files at boot time or if you add or remove hardware while running. In addition, the Linux 2.6 kernel brought enhanced hardware support, including better compatibility with various devices and file systems. The 2.6 series continued until August 2011, after which it transitioned to version 3.0.
