Abstract
A multi-processing system ( ) comprises a plurality of groups, each having an arbitrary number of processing systems ( ). Memory coherency may or may not be established within any particular group. However, each group is intentionally arranged by functionality so that memory coherency, if implemented, only needs to be maintained within the group. Information transfers between two groups are therefore non-coherent by definition. Memory coherency implementation is significantly reduced in the system. A transaction format utilizes group and processing system identifiers to implement the simplified coherency scheme.
