Abstract
An electronic device is provided which comprises a microprocessor for executing a program code and a first hardware code path verifying (CPV) stage coupled to the microprocessor. The hardware CPV stage comprises a first error detection code (EDC) generator configured to continuously determine an error detection code on a continuous sequence of code relating to an actually executed portion of the program code and to compare the actual error detection code with a predetermined error code so as to verify correct execution of the program code and to indicate an error.
