A data processing system is provided comprising at least one processing unit ( 10 ) for processing data; a memory means ( 40 ) for storing data; and a cache memory means ( 20 ) for caching data stored in the memory means ( 40 ). Said cache memory means ( 20 ) is associated to at least one processing unit ( 10 ). An interconnect means ( 30 ) is provided for connecting the memory means ( 40 ) and the cache memory means ( 20 ). The cache memory means ( 20 ) is adapted for performing a cache replacement based on reduced logic level changes of the interconnect means ( 30 ) as introduced by a data transfer (DO-Dm) between the memory means ( 40 ) and the cache memory means ( 20 ).
