Abstract

A system, apparatus and method for protecting coherent memory contents in a coherent data processing network by filtering data access requests and snoop response based on the Read/Write (R/W) access permissions. Requests are augmented with access permissions in memory protection units and the access permissions are used to control memory access by home nodes of the network.
