Socorro, NM — (PR excerpt) — FSMLabs announced the immediate world-wide availability of its RTLinuxPro Development Kit 1.2 for construction of real-time control software.

The RTLinuxPro DevKit contains a complete development system including: a newly optimized and extended version of FSMLabs' RTLinux RTCore hard-real-time operating system, a rugged and QA-tested Embedded Linux kernel, an embeddable file system and utilities, and a full set of GNU development tools matched to the supplied kernels and application software.

The latest revision of the RTCore hard real-time kernel provided with the RTLinuxPro DevKit 1.2 offers a number of optimizations and new features, including . . .

• The scheduler has been rewritten using priority queues and a number of techniques aimed at reducing lock contention and interrupt delay. As a result, RTLinuxPro 1.2 has significantly better timing than earlier versions. For example, the worst case native scheduling jitter on the Compaq IPAQ using a 203MHz StrongARM has been reduced from 60 microseconds to 30 and worst case jitter on current generation x86 based systems is well below 20 microseconds. The “scheduler advance” capability can be used to reduce jitter arbitrarily.
• On the high end RTCore now supports: SMP with processor reservation on x86 and PowerPC for applications that require every microsecond of performance; direct VME access; both Intel P4 Xeon and AMD GHz processors; And a powerful SMP capable process space (user-mode) real-time thread sub-system. On the low end, RTLinuxPro can run comfortably on the Cirrus ARM720T, AMD Elan 520, Intel StrongARM, and PowerPC 8xx and 82xx processors.
• RTCore also supports zero-copy real-time networking on Ethernet and FireWire (1394) via the LNet extension. LNet enables hard real-time control of networked devices as well as facilitating the use of real-time networking to control data flow and perform fault recovery for enterprise applications.

“RTLinuxPro DevKit 1.2 is a third generation product — the result of our extensive regression test system, lessons learned from the world-wide deployment of the two earlier versions of the DevKit, a significant effort on new documentation, and an extensive rewrite of RTCore internals to meet demands for higher reliability and performance,” said Cort Dougan, FSMLabs Engineering Director.
