    341341Interface base development model (normal known as COM in Microsoft’s world) is very helpful for large scale software development. Major commercial RTOS like vxworks, lynxOS support IDL/COM. Introduce IDL and COM model need an idl compiler, and also there are lots type of COM to choose in open source world. There is support for omniORB in RTEMS, however, omniORB lack feature for recent language like JAVA. The popular COM/COBRA choices are Universal Network Objects from Sun (used in openoffice), XPIDL by mozilla and SWIG (http://www.swig.org/) to name a few.

     345RTEMS currently does not take advantage of the SPARC V8 bit scan instruction.  The LEON CPUs should have these instructions and will benefit from them being supported by score/cpu/sparc.  It appears that using the generic bitfield code does not impact performance as much as it does memory usage since the generic code includes a 256-byte array.
