FIELD: physics; computer engineering.
SUBSTANCE: present invention relates to systems for switching modes of operation of a device. The system implements the method of providing for switching between privileged and non-privileged modes of operation. The method involves stages for running applications in non-privileged mode, a stage for generating interruption for request of services of a privileged function and a stage for switching to privileged mode for execution of a privileged function. The privileged function is executed as part of the same flow of execution in which the application is run.
EFFECT: provision for switching between privileged and non-privileged modes, which allows for simplifying planning and latency of a dispatcher.
