Enea continues to add value to one of the most widely developed RTOSes

Enea OSE® version 5.7 available now
STOCKHOLM, Sweden, June 17, 2013 – Enea® (NASDAQ OMX Nordic:ENEA) today
announced version 5.7 of the Enea OSE real-time operating system (RTOS), adding
significant performance upgrades and new functionality. Enea OSE is optimized
for communication systems in the areas of wireless devices, telecom networking
systems, medical equipment, automotive and transportation equipment, industrial
automation and other embedded systems.

“We see a continued strong demand for OSE, and are investing in feature growth
in close co-operation with our customers and partners”, said Markus Malmgren,
director of products, Enea. “With the latest improvements in OSE 5.7 we continue
to bring value to the ecosystem, making us fit for purpose in new product
generations and prolonging the lifecycle of today’s products.”

  · The target interface of Enea OSE 5.7 is redesigned, lowering the kernel call
overhead and improving common system call performance. Also, a flat interrupt
model is introduced, adapting to the increased abstraction in modern hardware
device architectures and their capability to buffer information. This allows OSE
to run without nested interrupts, which in live telecom networks has caused
throughput gain of 3.5-5%.
  · Further enhancements include updated compiler support to GCC version 4.6.3,
bringing support for new instructions sets and taking advantage of features and
optimizations in the compiler. Based on tests in real live telecom networks the
footprint decrease is 10% when compiling with “-Os” instead of -O3, without
performance decrease.
  · In Enea OSE 5.7 the memory manager implementation has been optimized and it
is now possible to configure it to allow optimization for address translation
performance over memory consumption. The faster handling of large pages in the
Translation Lookaside Buffer (TLB), which in live telecom networks has a
performance increase of 2-5%, is also improving the OSE heap manager
performance.
  · Finally, new hardware support includes the Freescale® QorIQ® T4240 and
QorIQ® Qonverge B4860 System-on-Chip (SoC) architectures (with e6500 Power
Architecture® cores), and the QorIQ® P5020 and P5040 (with e5500 Power
Architecture® cores).

Enea OSE is one of the most widely deployed RTOSes on the planet, especially in
networking infrastructure. It is a high-performance RTOS optimized for
distributed, fault-tolerant systems requiring high performance and high
availability. It has proved itself in numerous occasions, shortening development
time, enhancing reliability and reducing life time maintenance costs.

Enea OSE features a kernel design that blends the ease of the use of symmetric
multiprocessing (SMP) with the performance and scalability of asymmetric
multiprocessing (AMP). Enea Hypervisor implements multiple high performance
computing environments on top of multicore processors that benefiting developers
of next generation network equipment with lower development costs by enabling
hardware consolidation, increased performance in the system with higher
throughput and shorter development time.
