Abstract RU 2458389 C2

FIELD: information technology.

SUBSTANCE: single-chip computer includes at least one first processor core and at least one second processor core constructed on a common chip. The at least one first and the at least one second processor cores are interconnected via a processor interface. Data can be read via a separate or common memory interface from a separate or common data memory respectively and/or stored in said data memory. The single-chip computer includes an encryption and decryption unit which is assigned to the at least one second processor core and which is constructed and functionally arranged between the at least one second processor core and the memory interface in such a way that data which can be exchanged between the at least one second processor core and the data memory can be encrypted and decrypted by the encryption and decryption unit.

EFFECT: data protection through physical and logical separation of processor cores on the chip.
