FAULT PROCESSING SYSTEM

摘要

PURPOSE:To limit the effect of the fault for the multi-processor control exchange system by giving the fault processing through one of the central processors in case some fault occurs at the network control processor and performing the exchange process with other processors. CONSTITUTION:For instance, if some fault occurs at processor 2-1, the fault is informed to fault processor 3-0. And processor 3-0 sets up the blocking flag concerning processor 2-1 on the blocking flag holding register 14 at interface part 4. Thus the access to processor 2-1 is inhibited when the occupancy process is given for bus 6 in view of securing an access to processor 2-1 while the general exchange action is performed by central processor 3-j, 3-k and others. And the relation call process to processor 2-1 is held by queuing matrix buffer 15-j and others.
