We are now in a period when real-time operating system development is proceeding handin- hand with the evolution of processor silicon. The most interesting thing to happen to processor silicon over the past year is the advent of multi-core CPU chips with hardware support for virtualization of operating systems. These processor developments are enabling a new generation of real-time systems that combine fast responsiveness with reliability and lower system cost. Using system software enabled by the new processor features, real-time operating environments can now work cooperatively with a wider range of application environments than has been possible before.
Virtualization support in silicon is being promoted by CPU vendors as a technique for enabling more-efficient servers to be built for commercial applications, but it has the potential of benefiting embedded RTOS applications just as much or more. The new processors hardware support for virtualization enables more efficient sharing of a single hardware platform between multiple operating systems. In the case of embedded applications, this allows for more secure and reliable partitioning of I/O resources between real-time and general-purpose operating system tasks. The new processors simplify the development of high-performance multi-OS systems by performing in hardware many of the functions that traditional virtual machine managers (VMMs) have performed in software.
