The most versatile and high-performing RTOS yet by Enea for ARM-based architectures

STOCKHOLM, Sweden, February 24, 2014 – Enea® (NASDAQ OMX Nordic:ENEA) today announced the release of version 5.7.1 of the Enea OSE® real-time operating system (RTOS), bringing significant feature growth and performance gain to embedded real-time systems based on the ARM® CortexTM-A and CortexTM-R processor architectures.

“With our latest additions to the ARM version of Enea OSE, we are really surfing the momentum that this architecture is experiencing right now,” said Tommy Englund, Director of Products, Enea. “Old and new users of Enea OSE will experience a robust RTOS with extraordinary real-time characteristics and execution performance, a multicore scalability outshining even Linux, and easy software migration and portability thanks to its POSIX compatibility.”

Among the most prominent additions, the kernel system call framework has been highly optimized. Performance tests show a up to 50% lower system call execution times.

The design of the kernel interrupt management has been significantly improved in order to meet very high requirements on interrupt latency in multicore use cases. Enea OSE is, due to its hybrid SMP/AMP kernel design, very suitable for embedded multicore situations where both a rich POSIX programming environment and real-time characteristics are needed on the same processor.

“This latest RTOS upgrade is a strong move towards our shared goal of delivering optimal performance across cores and clusters in processing, power efficiency and system-wide communications," according to Charlene Marini, vice president of marketing, embedded segment, ARM. "It's evidence of the continuing value that Enea delivers to the ARM ecosystem and the network infrastructure market."

In this latest release, Enea OSE introduces the support for Network File System (NFS) version 4, allowing a system to share common files and directories among multiple users or machines over a network. It also brings new levels of debugging capabilities with the introduction of Enea Optima 2.8 support, including improved log analysis and log management.
