Abstract
Abstract Each of processor units 31-1-31-n comprises a CPU, memory, and interface function. A high-speed communications network 32 interconnects the processor units for inter-processor communications. Each of input/output units 33-1-33-n stores multimedia data and transmits the multimedia data through the network under the control of the corresponding processor unit. A processor control unit 34 controls the process of each of the processor units 31-1-31-n according to the process request received through the network. A switch 35 connects each of the input/output units 33-1-33-n to the network and exchanges data through the network. A communications line 36 transfers an instruction, etc. from the processor control unit 34 to each of the processor units 31-1-31-n.
