Abstract

A method for the coexistence of software having different safety levels in a multicore processor which has at least two processor cores (2, 3). A memory range (4, 5) is associated with each processor core (2, 3) and a plurality of software (SW1, SW2) is processed on one of the processor cores (2, 3) having a predefined safety level. The plurality of software (SW1, SW2) is processed having a predefined safety level only on the processor core (2, 3) with which the same safety level is associated, in which during the processing of the plurality of software (SW1, SW2), the processor core (2, 3) accesses only the protected memory range (4, 5) which is permanently associated with this processor core (2, 3).
