METHOD OF COMPUTATION PROCESS CONTEXT SWITCHING DURING PROGRAM INTERRUPT OR SUBROUTINE JUMP Russian patent published in 2008 - IPC G06F9/42 G06F9/48 

FIELD: information technologies.

SUBSTANCE: storing and restoration of computation process context in processor is two-staged. At the first stage the program counter and processor state counter values are automatically saved in context stack. At the second stage the required number of addressable context register groups is software saved. Processor operates with data memory segments through its own virtual file registers. And storing of base addresses of all virtual register files is performed by issuing just one command.

EFFECT: higher task context and procedure stepping rate with smaller amount of hardware resources used.
