RTOS gains Linux binary compatibility
The latest LynxOS real-time operating system from LynuxWorks incorporates Linux binary compatibility and enhancements in networking, porting support, and performance
Squarely positioned to set a new industry benchmark for performance and openness, LynxOS 4.0 adds an array of new enhancements that have been designed to attract customers away from using similar products offered by Wind River, QNX, and other off-the-shelf or in-house proprietary operating systems.

RTOS makes the most of multicore processing
Real-time operating system evolves to help software developers create more powerful devices using today's most advanced hardware and chipsets, including multicore processors
LynuxWorks is offering LynxOS 4.0 as a stand-alone solution with a selection of tools, or as part of several new industry specific software solutions.
"With this new version of LynxOS, our customers can leverage significant technological advances such as increased real-time performance and the latest in networking technologies", said Inder Singh, CEO of LynuxWorks.
"In addition, with the application binary interface (ABI) compatibility, we offer unprecedented levels of openness and compatibility between Linux and LynxOS, which gives customers a strategic advantage when using our products.
For the first time, embedded developers can truly plan long-term and be assured that as their products and market requirements change, they can quickly migrate between operating systems, or add new products that are compatible with very little effort".
Unique in the high-performance RTOS world, LynxOS also offers its users the Linux processing model, Posix conformance and open, standard application programming interfaces (APIs).

The result is that OEMs have access to a larger pool of programming talent, and a greater choice of compatible applications and tools, decreasing overall development times and related costs for new embedded products.
Recent internal tests show that LynxOS 4.0 task response has been improved over the previous release by over 30%.
It exhibits true linear scalability, remaining deterministic regardless of the number of tasks performed at any point.
Absolute determinism and kernel threading allow for interrupt routines to be short and fast, ensuring predictable response even in the presence of heavy I/O.
Systems based on LynxOS are able to perform their multiple tasks more reliably and deterministically than previously possible.
The only hard real-time operating system to offer true application binary interface (ABI) compatibility to Linux, LynxOS 4.0 lets users run Linux applications unmodified under LynxOS or to augment real-time applications on LynxOS with applications from Linux.
The innovative capability eliminates porting and maintenance issues when migrating existing Linux applications to the hard real-time LynxOS platform.
The compatibility is implemented through the use of dynamically linked shared libraries for minimum intrusion into the kernel, providing flexibility while maintaining stability and compatibility.
LynxOS 4.0 gives developers access to state-of-the-art networking technology.
The new networking capabilities make it the most advanced of all the commercial RTOS offerings, with features such as IPSec, IPv6 and an integrated firewall.
The TCP/IP stack has been enhanced for re-entrancy, determinism and performance, and includes the latest protocols for networking and routing, such as OSPFv2, BGP-4 and RIPv2.
Tests, with small packets where 100BaseT wire speed is not a limiting factor, showed performance increases by more than 90% over the previous LynxOS release.
This is due to enhancements to the new stack for better throughput and drivers optimised for speed.
Gigabit Ethernet support is also provided with performance at up to 93% of wire speed.
This will enable LynxOS users to quickly deploy systems with the latest in networking technology.
