METHOD FOR SYSTEM INITIATION OF MULTIPROCESSOR SYSTEM

摘要

The initialization of system process boards, a CPU board and I/O boards is executed in parallel and the initialization of each board is executed execlusively to initialize multiprocessing system effectively. The method includes the steps of: (A) checking contents of a ROM when board a reset signal is received; (B) checking function of RAM and checking that 0 is stored in a RAM as an initial value; (C) checking a real time clock; (D) checking interrupt bus (IB); (E) checking a dual universal asynchronous receiver transmitter (DUART); (F) checking peripheral interface adapters; (G) initializing system memory board (3) and sending system ready (SYS-READY) signal to processor boards; and (H) initializing processor boards exclusively and receiving IAMALIVE signal transmitted from processor boards.
