US Patent 9858199 Memory management unit for shared memory allocation

A system and method for allocating shared inter-process memory by a memory management unit is disclosed. A memory management unit may receive information indicative of allocating a region of shared memory. The information may further indicate that a second process may share access to the memory. The memory management unit may identify corresponding regions of virtual address space for each process, such that the region in each address space maps to the same range of addresses. The memory management unit may virtualize access to the shared memory by mapping from the corresponding regions of the virtual address space.
