Expands POSIX support for multi-threading, adds distributed computing and hot swap for Pentium

SAN JOSÉ, Calif.—September 20, 1999—Lynx Real-Time Systems, Inc., today announced the latest release of the LynxOS® real-time operating system (RTOS), significantly extending Lynx leadership in high availability and standards for the embedded software industry. LynxOS version 3.1 includes the most complete implementation of the POSIX® standard thread support available in a commercial RTOS, a highly efficient software foundation for linking distributed computing systems, and the first RTOS support for CompactPCI®-based Hot Swap using the Intel® family of processors.

"The embedded market is demanding RTOS solutions with the productivity advantages of industry standards along with OS kernels that support high-availability and distributed computing architectures, said Bill Hogan, president and CEO of Lynx. "Lynx continues its pioneering trend in addressing these needs with LynxOS, a full-featured, hard real-time operating system."

LynxOS version 3.1 provides the industry's most complete implementation of POSIX 1003.1c thread support, complementing Lynx full conformance to POSIX 1003.1 and compliance to 1003.1b. This standard enables the reuse of vast amounts of software available on UNIX-compatible systems such as Solaris from Sun Microsystems.

The LynxOS Messenger, a new extension to LynxOS, provides a high-performance data communications facility for linking distributed computing architectures in high-availability systems. This facility offers a very flexible communication option especially suited for hard real-time applications and deeply embedded systems (see "Lynx Introduces Advanced Messaging Technology for Distributed Computing Architectures" dated September 20, 1999).

LynxOS version 3.1 is the industry's first commercial RTOS to support hot swap applications of Pentium-based CompactPCI systems targeted for high-availability telecommunications applications (see "Lynx Adds Hot Swap Support for Pentium Processors" dated August 23, 1999). Lynx will initially support the Motorola CPX 8216 high-availability computer system using redundant MPC5350 Pentium-based system controllers.
