PURPOSE:To simplify the constitution of a hardware, by enabling a bootstrap program to be accessed commonly by respective system. CONSTITUTION:Plural firmware systems 1 and 2 are connected to a storage part 6 which stores the bootstrap program, a loader program, and plural object programs via a system bus 4. MPUs 31 and 32, local memories 71 and 72, and address mapping circuits 51 and 52 are provided on the systems 1 and 2 respectively. When the systems 1 or 2 is reset, the circuit 51 or 52 is operated, and the loader program of the main storage part 6 is transferred to the local memory 71 or 72 by the bootstrap program of the main storage part 6 receiving the conciliation of a bus 41 by the MPU 31 or 32. The systems 1 and 2 execute processings by the loader program stored in the local memories 71 and 72. |
