Realtime OS Jaluna

rkgmd writes "Jaluna-1, a software component suite based on the respected chorus realtime os is now available in opensource (MPL-derived license) form. Jaluna, the company behind this, is a spin-off from sun to promote and develop chorus, and consists of many developers from the original chorus team before it was acquired by Sun. Chorus developed one of the earliest successful microkernel-based rtos's (could even run parallel, distributed unix in realtime on inkos transputers in 1992). Lots of good research papers here, and a link to the original newsgroup announcement."

Re:QNX

[wfmcwalter]

At least as far as the kernels are concerned, ChorusOS and QNX-neutrino are quite similar - both are realtime, microkernel based, protected-mode embeddable OSes, available for a number of microprocessors and embedded boards. Most of this (with the exception of the micrkernel part) is also true for Windriver's VxWorks AE RTOS.

VxWorks' and QNX's advantage over ChorusOS was a combination of wider BSP support and very mature toolchains. ChorusOS big advantage was that it was specifically targetted at distributed applications - this is a issue for applications that combine real-time performance with data-centre-like reliablility (particularly telco).
