Abstract: Techniques and examples pertaining to memory coherence management with a snoop mechanism and snoop filter structure for multi-port processors are described. A method may involve receiving a request from a first processor having a first plurality of local memories and more than one snoop ports. Responsive to the request, the method may involve snooping one or more snoop ports of a second processor having a second plurality of local memories without snooping any of the more than one snoop ports of the first processor.

Abstract: A memory management apparatus and method thereof are disclosed. The memory management apparatus includes a micro translation look-aside buffers, a main translation look-aside buffer, a page address history table and a controller. The page address history table is used to record the space size information for a plurality of page table entry which are written to the main translation look-aside buffer. The controller decides to whether access a page table entry or not from the main translation look-aside buffer according to the page address history table.
