Arithmetic unit e.g. microprocessor device, controlling method for controlling e.g. engine of motor vehicle, involves defining reciprocal access rights between program parts in volatile memories of various sources for arithmetic unit

摘要

The method involves defining reciprocal access rights (118, 120) between program parts (110, 112) in volatile memories of various sources for an arithmetic unit (102). The parts in the volatile memories of the various sources are partitioned. A membership of a program component of the program parts in the memories is defined, and an indication for a combination between the program parts in the volatile memories is generated. Independent claims are also included for the following: (1) a computer program comprising a set of instructions for performing a arithmetic unit controlling method (2) a computer program product comprising a set of instructions for performing a arithmetic unit controlling method.
