A popular OIS product is the `F33f`_`[ORBexpress`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=ORBexpress]`_`f `F33f`_`[CORBA`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=CORBA]`_`f `F33f`_`[middleware`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Middleware]`_`f software. ORBexpress is most popular in the `F33f`_`[real-time`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Real-time_computing]`_`f and `F33f`_`[embedded computer`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Embedded_computer]`_`f markets.`:cite-ref-diicoe-3-1[`F5bf`_`[3`#cite-note-diicoe-3]`_`f] OIS supports the software version ORBexpress on more than 6,000 computing platforms (combinations of the versions of `F33f`_`[CPU`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=CPU]`_`f families, operating systems, and language compilers).`:cite-ref-rt-platforms-8-0[`F5bf`_`[8`#cite-note-rt-platforms-8]`_`f]`:cite-ref-ois-platforms-9-0[`F5bf`_`[9`#cite-note-ois-platforms-9]`_`f] OIS also has `F33f`_`[FPGA`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=FPGA]`_`f versions of ORBexpress to allow hardware blocks on an FPGA to interoperate with software.`:cite-ref-automation-isr-techn-10-0[`F5bf`_`[10`#cite-note-automation-isr-techn-10]`_`f]
OIS engineers invented a form of communications security called the `F33f`_`[Partitioning Communication System`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Partitioning_Communication_System]`_`f or PCS.`:cite-ref-mils-7-1[`F5bf`_`[7`#cite-note-mils-7]`_`f] The PCS is a technical architecture that protects multiple Information Flows from influencing each other when communicated on a single network wire.
