Multiprocessor computer system having improved coupling arrangement for independently operating local processor systems

摘要

A computer system having a plurality of mutually independently operating processor systems, coupling elements and a system bus which connects the processor systems and a central decision logic unit for administering the system bus. The computer system includes at least two processor subsystems that are connected by the system bus and each includes a plurality of the independently operating local processor systems. The local processor systems of a processor subsystem are connected with one another or with the system bus by way of a coupling element. A decision logic unit within the coupling element here determines, as a function of a fixed priority rule, the sequence of processing of communications requests.
