INTERCONNECTION MECHANISM OF VIRTUAL I/O

摘要

PROBLEM TO BE SOLVED: To enable a transaction the address of which is specified in a failed component to request an alternate component. SOLUTION: This interconnection mechanism of virtual I/O comprises an address decode block having a multiplexer 172 which generates an address 173 in relation to a processing unit related transaction by multiplexing input, a range register decoder 174 which receives the address and provides a destination address 175 of a module for receiving the transaction in relation to the address and a reroute module ID block 176 which receives the destination address and a reroute module ID block having an original module ID 182 which provides addresses of one or more original modules in a computer system and a remapping module ID 183 which provides a logical destination module ID of an alternate module in the computer system.
