ABSTRACT:
To increase the versatility of a central processing unit (30) controlling an operating apparatus, such as apparatus including an engine, installed in an automotive vehicle, a main read-only memory (ROM, 40) stores not only operating data of the vehicle and/or the engine, but additionally, the organization program of the central processing unit (CPU, 30) in modular, or block form in the ROM (40). An auxiliary ROM (41) preferably an electronically erasable ROM is connectable, via an interconnection bus (80) to the CPU (30) and an initial program stored in the main ROM (40) provides a determination or recognition step to be carried out by the CPU (30) first, to determine if the auxiliary EPROM (41) is present; and, if so, to then address the auxiliary EPROM (41) for control of the program run of the CPU; if not, to take programming operating data directly from the ROM (40). The programming stored in the auxiliary EPROM (41) may direct the CPU (30) to carry out programming steps stored in the main ROM (40) in the stored sequence, or in changed sequences, as well as to take operating steps directly from the auxiliary EPROM (41). All programming data are stored in the auxiliary EPROM (41) also in modular or block form, and preferably include diagnostic programs relating to monitoring a function of the vehicle or of the engine, under control of data computed by the CPU (30).
