PROBLEM TO BE SOLVED: To provide memory management capable of generating a rapid hit.SOLUTION: Memory management is provided within a data processing system 2 which includes a memory protection unit 8 and defines memory regions within a memory address space which extend between base addresses and limit addresses and have respective attributes associated therewith. When a valid hit occurs within a memory region, then block data is generated comprising a mask value and a TAG value (derived from an original query address) which may then be used to identify subsequent hits within at least a portion of that region using a bitwise AND.SELECTED DRAWING: Figure 1 |
