Abstract:
A computer system having a plurality of subsystems, each subsystem operative to communicate with at least one other subsystem, the computer system comprising:bus interface logic in each subsystem, the bus interface logic converting data from the subsystem into serial format for transmission and converting serial data received into a format usable by the subsystem; a plurality of serial output paths, each serial output path carrying serial data to one of the subsystems; a plurality of serial input paths, each serial input path carrying serial data from one of the subsystems; and communication interconnection logic connected to each serial output path and to each serial input path, the communication interconnection logic operative to (a) receive data from bus interface logic through a corresponding serial input path, (b) buffer the received input data only if the serial output paths are in use, and (c) simultaneously transmit received data to each bus interface logic through all serial output paths.
