CORBA middleware supports real-time Linux

Nov 12, 2007 — by Eric Brown — from the LinuxDevices Archive — 6 views

Objective Interface Systems (OIS) is shipping a version of its real-time CORBA ORB (object request broker) middleware targeting Wind River Linux. ORBexpress RT supports both Wind River's General Purpose Platform, Linux Edition, and Real-time Core, the company's POSIX-compliant real-time add-on.

According to OIS, the integration is targeted primarily at developers of “non-mission-critical military/aerospace applications,” as well as telecom applications for software defined radios (SDRs), network infrastructure, image processing, and mobile handsets. Specific applications mentioned include aircraft communications with ocean sonar buoys and face-recognition programs.

Stated Joe Jacob, senior vice president of OIS, “Adding only minimal overhead, ORBexpress makes seamless communications easy among real-time and embedded devices in heterogeneous environments. ORBexpress simplifies development of multiple generations of products, both speeding development and saving money.” Jacob went on to note the benefits for ORBexpress developers, including Wind River's Workbench development environment and “world-class technical support” for Linux-based embedded applications.

The Wind River integration is the second major partnership announcement this month from OIS regarding its ORBexpress RT, an object request broker (ORB) based on the real-time CORBA (common object request broker) standard. ORBexpress RT is said to be a run-time environment that enables integrated communications between real-time and embedded devices in diverse environments. Available in C++, Ada, and Java, ORBexpress “has been recognized repeatedly as the smallest and fastest ORB in the industry by a variety of independent benchmark tests,” claims OIS.

Wind River's General Purpose Platform, Linux Edition is comprised of the Linux 2.6 kernel, integrated patches and packages, the company's Eclipse-based Workbench development suite, and a variety of networking and run-time technologies. Real-Time Core for Wind River Linux is based on the embedded version of RTLinux, which Wind River acquired from FSMLabs in February. The Core coexists with the Wind River Linux kernel to provide “hard real-time application determinism performance” for applications requiring extremely tight timing constraints, such as single-core phones, high-bandwidth IP communications, robotics and industrial control.
