LynxOS RTOS Family

We expect all our embedded market segments, from military and aerospace to industrial, medical and office automation, to benefit from the security and networking improvements in this next generation of LynxOS.

Time partitioning is done through a fixed-cyclic time-slice scheduler, which allocates periods of time to each partition. Consequently, OEMs can rapidly implement advanced features and functions to differentiate their products from the competition. The RTOS can run a shell on a serial port for a developer to interact directly with the target machine.

These file systems can be mounted read-write or read-only for additional flexibility in safety-critical environments. By using lnxos site, you agree to the Terms of Use and Privacy Policy. The static device info files are used to configure the static device drivers for devices available in the target system. The BSP contains routines for initializing and controlling hardware on the target system. Download a PDF brochure.

LynxOS has proven itself in ALL major embedded markets with deployments in telecom, networking, medical, industrial automation, consumer, office automation, and mil-aero.

An event is a synchronization object used to notify the occurrence of a condition to processes that may wait for it. And this determinism extends to networking applications, which can stay responsive even in the face of the most complex demands. A queuing port is a communication object allowing a partition to access a channel of communication configured to operate in queuing mode.

Lynx Software Technologies software provides the hidden intelligence that empowers, protects and secures our modern world. All safety-critical related markets will benefit from LynxOS including both civil and military aviation, rail, transportation, and ground vehicles. This means they need to run more full functioned operating systems, with connectivity and popular human interfaces, require more processing power, including multi-core chips, and are likely to be exposed to the same types of cyber attacks that we are facing in our corporate and personal computers.


The Usenet newsgroup comp. There are four rts of Intrapartition Communication service requests: It’s as if each partition were its own separate computer. The static device drivers are software components that isolate specific details of hardware devices from application software components. LynxOS satisfies the percent MCDC structural coverage requirement out-of-the-box, allowing systems developers to concentrate on their applications rather than trying to get those last lines of system code exercised for system certification.

At the point in the LynxOS initialization where the OS is rtow to run partitions, cinit transforms into a unique Pinit process in each partition.

LynxOS RTOS Family (Operating systems – embedded) from LynuxWorks, Inc. – Embedded Computing Design

InLynx introduced rrtos specialized version of LynxOS called LynxOS, especially for use in avionics applications that require certification to industry standards such as DOB. Our newest release, LynxOS 7. The static device info files are linked with the LynxOS kernel. This offers a very easy migration rtps systems and applications based on Linux or Unix, and also allows for LynxOS applications to be prototyped on native Linux systems.

The net result is that Lynx Software Technologies customers not only come to market quickly with high-quality real-time systems, but are able to more effectively provide value to their own customers over the long term.

Retrieved from ” https: Unix and Unix-like operating systems. Items such as hardware-dependent interrupt handlers for example, power warn and load shed and kernel threads are added to the kernel with device drivers.

Compatibility with other operating systems, including Linux, followed. This article is about the real-time operating system. Hence there are no new tools to purchase and no new learning curves to climb in order to extend code investments across both the open-source and hard real-time worlds.


A buffer is a communication object used by processes of a same partition to send or receive messages. Because POSIX conformance ensures code portability between systems, it is increasingly mandated for lyndos applications and government contracts.

Our new powerful RTOS security features allow embedded developers to design their systems to be more secure before they are connected to the internet.

LynxOS offers developers the flexibility of advanced networking features that are unmatched by the competition. Download a PDF brochure. A counting semaphore is a synchronization object commonly used to provide access to partition resources. ABOUT US Every day, millions of people worldwide are touched by products that rely on Lynx Software Technologies software—from Internet and phone communications, to airline flight-control systems, office automation and medical devices.

These device info files are stored in the file system and installed after the LynxOS kernel is booted, but before partitioning is invoked. Full Memory Management Unit support has been included in the kernel sincefor the reliability of protected memory and the performance advantages of virtual addresses. The boot code boots the host processor and performs the appropriate level of power on self-test POST to assure correct operating conditions of a limited set of hardware devices.

The documentation set includes a detailed partitioning and interface analysis that focuses on time, space and resource partitioning as well as timing margin analysis so developers can allocate budgets to use operating system services.

The dynamic device information files are used to configure the dynamic device drivers for optional devices on the target system. This real-time operating system is designed specifically to fulfill the stringent needs of multithread and multiprocess applications in safety-critical real-time systems.

The RTOS device drivers permit mounting an external disk drive to facilitate testing and data capture.
