ELECTRONIC CONTROL UNIT HAVING REAL-TIME CORE MANAGING PARTITIONING Russian patent published in 2014 - IPC G06F9/50 

FIELD: physics; control.

SUBSTANCE: group of inventions relates to electronic control units. Disclosed is an electronic control unit including a microcontroller provided with RAM containing variable data, and ROM, associated with the code of an operating software system having a built-in real-time core for executing computer tasks, the RAM and ROM comprising areas corresponding to partitions, one of which is allocated to the real-time core and each of the other partitions is allocated for at least one of the tasks, the ROM and RAM are linked by an address bus which is physically programmed to prevent writing in the other of the RAM areas and prevent execution of the other of the ROM areas, wherein the real-time core is linked to a timer allocating an execution time for each partition, wherein the electronic control unit is designed such that only two partitions can be executed at a given moment in time, and the microcontroller is designed to control only four buffers for said two partitions: a buffer for the code and a buffer for data of the partition allocated to the real-time core; a buffer for the code and a buffer for data of the partition allocated to a task which is active at said moment in time.

EFFECT: faster operation of electronic control units.
