Abstract
A microprocessor having registers is provided with a subset of instructions and is capable of operating in association with an operating system. The subset of instructions can be issued by an application running on the microprocessor for saving at least a portion of at least one of the plurality of registers not saved by the operating system during interrupt processing. Such an arrangement enables applications to be written for advanced microprocessors which have word lengths and register widths which exceed the word and register sizes for which the operating system was designed.
