Abstract
The invention concerns the transfer of data information in a multiprocessor computer system. If data information has to be transferred between two processor units then the associated control information is made available on a connection bus and the data information is transferred afterwards via a switch unit from the first to the second processor unit. If however data information is to be transferred from a sending processor unit to all other processor units (broadcast transfer) then not only is control information transferred via the connection bus but subsequent data information too; a transfer of data information via the switch unit does not occur in this case. In this manner it is possible to reduce the outlay for the switch unit in terms of circuitry and programming.
