Mercury Computer Systems Announces LNXexec, the Open, Standards-Based Software Platform with Full Linux Programming

MCOE with LNXexec offers performance commitment with a full feature set for

critical real-time application processing

May 23, 2006, 01:00 ET from Mercury Computer Systems, Inc.

    CHELMSFORD, Mass., May 23 /PRNewswire-FirstCall/ -- Mercury Computer
 Systems, Inc. (NASDAQ:   MRCY) announced LNXexec, a Linux(R) programming and
 network environment for Mercury embedded computing solutions. LNXexec
 provides the full features of Linux with a rich set of application
 programming interfaces (APIs) for developing real-time multicomputer
     Introduced as part of the Mercury MCOE (Multicomputer Operating
 Environment) Release 6.4.0, LNXexec enables customers to migrate to the
 open systems environments, such as Open Architecture Computing Environment
 (OACE) and X-Midas, that are demanded by today's users.
     "Linux(R) is rapidly becoming the programming and networking
 environment of choice for the embedded, high-performance computing market,"
 said Brian Hoerl, Vice President of Worldwide Sales for Mercury's Defense
 business. "Mercury's LNXexec marks a significant milestone in our
 progressive offering of fully optimized and open solutions that deliver
 unparalleled performance for a customer's existing investment."
     LNXexec can be installed on top of the MCOE 6.4.0 software
 distribution, preserving existing Mercury investments and enabling any
 applications written to Mercury's multicomputer middleware APIs to migrate
 easily to Linux. Systems can be deployed with any combination of LNXexec or
 MCexec, Mercury's traditional POSIX-compatible operating system, on the
 system compute nodes. This "dual kernel" LNXexec/MCexec offering runs on a
 RACE++(R) Series configuration with a Motorola MVME5110 single board
 computer that provides VxWorks(R) runtime capabilities. Both
 cross-development and native development are supported.
     LNXexec offers the following benefits:
     * Integration - LNXexec facilitates the easy integration of standards-
       based software;
     * Investment maximization - current Mercury customers can preserve their
       software investment in the Mercury MCOE middleware;
     * Performance - LNXexec is a Linux kernel (2.6.12) with an embedded
       distribution customized for a Mercury PowerPC(R) compute node,
       supporting both Mercury's multicomputer middleware and standard Linux
       network features. For critical real-time processing, MCOE with LNXexec
       provides performance equal to or better than MCexec.
     * Full services - Mercury provides standard support for unmodified
       baseline VxWorks, MCexec, LNXexec, system management, board diagnostics,
       and development host integrated development environments (IDEs) and tool
       chains. Professional services are available for customers who need to
       modify the source code or base software/system configuration, such as
       modifying the Linux kernel, implementing different tool chains, and
       developing and porting industry-specific applications.
     LNXexec is separately priced and packaged, and is available with
 Mercury's standard license and bundle options. It can be purchased as an
 upgrade or as a new LNXexec and MCexec development environment. For more

 Mercury at (866) 627-6951.
