RT Linux applications targets VME platform

Concurrent Computer Corporation, which sells of integrated computer solutions and real-time Linux operating systems, announced the iHawkTM VME, a commercial platform for mission-critical simulation, data acquisition, industrial and aerospace applications. iHawk VME systems feature energy-efficient Intel Core multi-core technology on a single-slot 6U VME/VXS card.

At the heart of each iHawk solution is Concurrent's RedHawk Linux real-time operating system. Compatible with the popular Red Hat Linux distribution, RedHawk features high I/O throughput, fast response to external events and optimized interprocess communication. RedHawk is the ideal Linux environment for complex real-time applications.

RedHawk Linux is based upon a multithreaded, fully preemptible Linux kernel with low-latency enhancements. RedHawk's true symmetric multiprocessing support includes load balancing and CPU shielding to maximize determinism and real-time performance in time-critical solutions. A user-level application can be guaranteed to respond to an external event in less than 30 microseconds on a shielded processor.

"Customers of Concurrent iHawk PCI systems have leveraged the benefits of RedHawk Linux since 2001. With iHawk VME, RedHawk Linux is now available for VME/VXS form factor solutions," said Gary Beerman, Director of Marketing, Concurrent. "iHawk VME also provides an attractive Linux migration path for Concurrent's Power Hawk UNIX-based VME systems."

iHawk VME systems are ideal for real-time application environments that require ruggedized or special packaging. iHawk VME allows an easy upgrade path to RedHawk Linux while maintaining a user's VME I/O investment. A wide range of VME card options are available such as analog and digital I/O, MIL-STD-1553, ARINC 429, IEEE-488, reflective memory and asynchronous I/O. iHawk VME systems offer comprehensive integrated I/O including SATA, SCSI, EIDE, Flash memory, on-board disks, graphics, gigabit Ethernet, USB, RS-232 and GPIO.

iHawk VME systems also support Concurrent's powerful NightStarTM development tool set. Users can debug, analyze, monitor and tune their real-time applications on iHawk systems locally or remotely at application speed. Each tool runs non-intrusively, thus preserving the deterministic behavior of the application. NightStar tools allow developers to graphically view how their applications interact with the Linux kernel.

iHawk VME hardware options include Concurrent's Real-time Clock & Interrupt Module (RCIM), a multifunction I/O card designed for time-critical applications that require rapid response to external events. The RCIM includes a synchronized clock readable by multiple systems, up to 8 programmable timers and up to 12 input and 12 output external interrupt lines. An optional on-board GPS module is available to align the RCIM's synchronized clock to GPS standard time.

Concurrent's Special Systems group is available to design and deliver customized iHawk VME systems for the most demanding real-time applications. Concurrent engineers can provide special packaging including ruggedized peripherals and enclosures, integrate third-party I/O cards, develop and integrate RedHawk Linux drivers, and perform application rehosting. Hardware and software are designed and developed to exact customer specifications.
