Enea delivers an unprecedented combination of determinism and throughput in Linux

STOCKHOLM, Sweden, January 30, 2014 – Enea® (NASDAQ OMX Nordic:ENEA) today
announced the first commercial release of Enea LightWeight RunTime (LWRT),
making it possible for Communications and Networking equipment manufacturers to
secure their software application investments over time, and facilitating a
continuous technology evolution.
Enea LWRT is an execution environment contained in one Linux user space thread
and makes use of the technique of CPU/core isolation. By partitioning the CPU
cores of a multicore system, dedicated cores can be assigned to perform real
-time tasks in separation from the non-real-time tasks. This helps bringing
customers a deterministic Linux environment, and gives them optimal hardware
utilization and application performance.

The benefits of Enea LWRT are most clearly visible in a Communications or
Networking application context, e.g. in Radio Base Stations or Media Gateway
platforms, where the needs for determinism, minimal interrupt latency, and high
throughput are essential. Benchmark measurements show that Enea LWRT has an
average interrupt latency comparable to Linux with the PREEMPT_RT patch, but
with a worst case latency almost half as low, and a throughput  (netperf) almost
twice as high.

For existing customers using Enea’s compact kernel RTOS Enea OSEck, Enea LWRT is
the best alternative when introducing Linux into their products. It is a natural
technology bridge preserving their existing architectures and securing their
software application investments over time.

Enea is today a world leader in Linux system partitioning when applying the
NO_HZ patch in a commercial context, a position gained from the process of
developing Enea LWRT. Enea is heavily involved in the associated Community work,
and continues to invest into the evolution of LWRT and its applicability to a
wider market, by adding POSIX APIs to the solution. This will enable optimal
performance and determinism when running both real-time OSEck applications and
pure Linux applications on top of LWRT. At last native Linux will then have an
extension available, capable of fully satisfying the ever increasing industry
demands for system wide performance, robustness and efficiency.

About Enea Linux Enea drives the momentum of the open source evolution through
community participation in the Yocto Project and the Linaro Networking group,
and through a rich ecosystem of semiconductor vendors, Enea guarantees that any
choice of hardware is supported. For extreme performance requirements the Enea
Linux real-time solutions in multicore systems are of fundamental strength. Enea
is with you every step of the way in your software project, with a global
support organization.
