Abstract (en)

[origin: WO0052582A1] The aim of the invention is to increase the capacity of processor systems consisting of a large number of individual processors using the MESI state model to maintain the cache coherence inside the processor system. To this end, more states are added to the MESI state model, which is otherwise limited to four states. In this way, the state situations inside the processor system can be handled in a more differentiated manner and unnecessary bus accesses can be avoided. The processing capacity which comes available as a result can be used to increase the capacity of the system.
