<p>The present invention relates to a computer system with scalable multiprocessor architecture with a distributed physical memory which supports data with a divided virtual memory. There is no connection at all between the location of a data element in the machine and its virtual address. In particular, there is no home position in which a data element normally has to be situated. Instead, data automatically moves wherever it is required, which reduces access times and data traffic. The computer system consists of a hierarchy of buses and data control units which interlink an arbitrary number of processor/memory pairs, which constitute the only data memory of the system. Each data control unit has a set- associative status memory which contains information for data elements under its control. The control unit controls data transactions by sensing buses above and below it. The data access protocol used ensures automatic transfer, duplication and rearrangement of data with retention of data coherence and without loss of data from the system. <IMAGE></p> |
