Abstract
Run time modification of interrupt service routines in an embedded operating system installs a soft vectored interrupt service routine into the operating system kernel at the time of the kernel generation. The soft vectored interrupt service routine refers interrupt service calls to installable interrupt service routines that may be loaded subsequently on a real-time basis. In this way, flexible interrupt service routine response may be obtained for a wide variety of hardware combinations, unanticipated at the time of the generation of the operating system kernel.
