METHOD AND APPARATUS FOR INTERRUPT HANDLING Russian patent published in 2018 - IPC G06F9/48 

FIELD: computing; counting.

SUBSTANCE: group of inventions relates to computer engineering and can be used to handle interrupts in data processing systems. Device comprises a plurality of system registers, comprising a set of interrupt handling registers for controlling handling of an incoming interrupt; processing circuitry configured to execute software of the plurality of execution levels, interrupt controller circuitry configured to route said incoming interrupts to interrupt handling software that is configured to run at one of said plurality of execution levels; and register access control circuitry configured to dynamically control access to at least some of said interrupt handling registers depending on one of said plurality of execution levels to which said incoming interrupt is routed.

EFFECT: technical result is an increase in the flexibility of the interrupt handling software, while at the same time maintaining the security of the data processing device.
