QNX Software Systems has revealed the latest generation of its operating system and development tools for the automotive, industrial, medical, networking and defence markets. Version 6.5 of the QNX Neutrino real-time operating system (RTOS) and the QNX Momentics tool suite introduces many new capabilities, including support for ARM Cortex-A9 processors and Freescale Power e500MC processor cores, a persistent publish/subscribe service, a variety of performance optimisations, and an enhanced tool chain that includes Eclipse CDT 6.0, GCC 4.4.2 and GDB 7.0.
With version 6.5, Neutrino now supports symmetric multiprocessing (SMP) on ARM Cortex-A9 processors and Freescale Power e500MC processor cores. It can now also support SMP on multicore processors with up to 32 cores, providing scalability for compute-intensive applications in networking, image processing and other environments. Release 6.5 also delivers faster kernel performance under heavy memory utilisation and significantly higher file system throughput on many platforms. Other RTOS enhancements include support for Intel advanced programmable interrupt controllers (APICs), Intel message signalled interrupts (MSIs), and expanded support for x86 boards from Advantech, Intel and Kontron.
Version 6.5’s new PPS service can greatly simplify the design and maintenance of systems that integrate many disparate hardware devices and software components. In a home energy management system, for example, the service can allow sensors, thermostats, alarms and other components to be replaced or upgraded without requiring changes to the system’s human machine interface (HMI).
The Momentics tool suite offers a comprehensive Eclipse-based IDE with innovative profiling tools that help developers gain insight into system behaviour. Version 6.5 of the suite introduces support for the Eclipse platform 3.5.2, Eclipse CDT 6.0, GNU debugger (GDB) 7.0, binutils 2.20 and GNU compiler (GCC) 4.4.2. Compiler enhancements include optimised dynamic linking, including lazy linking and GNU hashing. The tool suite also includes performance enhancements to its system profiler, a visualisation tool that allows developers to analyse complex software behaviour on both single- and multicore systems.
