Microcomputer for vehicle controller/regulator has code coverage memory receiving information about addresses in program and/or data storage memory addressed by program

摘要

The microcomputer has a code coverage memory connected to a microprocessor in parallel with a program memory and a data memory via an address bus and a data bus. The code coverage memory receives information about which addresses in the program memory and/or data storage memory are addressed during the running of a control/regulation program from the program memory and operation of the vehicle in the context of read and/or write access. Independent claims are also included for the following: a method of determining the code coverage of a control/regulation program.
