ABSTRACT:
A fault-tolerant system has a predetermined system function and comprises a plurality of functional blocks. The fault-tolerant system uses selected ones of the functional blocks to construct the predetermined system function and uses a remaining one of the functional blocks to recover the predetermined system function when one of the selected functional blocks becomes a faulty functional block. The fault-tolerant system comprises a memory device for memorizing a plurality of block connection relationships each of which is representative of a functional block connection for providing the predetermined system function. A detecting device detects the faulty functional block to produce a fault signal. An accessing device accesses the memory device in response to the faulty signal to select a selected one of the block connection relationships that does not include the faulty functional block. A recover device recovers the predetermined system function in accordance with the selected block connection relationship.
