Data transfer between assemblies, esp. of multiprocessor system - using individual and simultaneous multiple addressing, reduced size of physical address space

摘要

The method of transferring data between assemblies enables initiation of transfer by at least one assembly which applies an address signal for addressing an assembly and communications unit control data to a bus system. - Each assembly decodes at least two addresses. One address (E3) addresses an individual assembly and the other (G3) addresses several assemblies simultaneously. For simultaneous addressing several assemblies either receive or transmit data simultaneously. Simultaneously transmitting assemblies only use part of the bus capacity each.
