Abstract: A method includes communicating a first message between processors of a multiprocessor system via a coherency interconnect, whereby the first message includes coherency information. The method further includes communicating a second message between processors of the multiprocessor system via the coherency interconnect, whereby the second message includes interprocessor message information. A system includes a coherency interconnect and a processor. The processor includes an interface configured to receive messages from the coherency interconnect, each message including one of coherency information or interprocessor message information. The processor further includes a coherency management module configured to process coherency information obtained from at least one of the messages and an interrupt controller configured to generate an interrupt based on interprocessor message information obtained from at least one of the messages.

Abstract: A processing device includes a first storage location configured to store a first value associated with a first address space, a second storage location configured to store a second value associated with a second address space, and a third storage location configured to store a third value associated with a third address space. The processing device further includes a memory management unit, which includes a first input configured to receive a first address value associated with a data transfer operation, a second input configured to receive an identifier associated with the data transfer operation, and an address space select module configured to identify a select value from the first value, the second value and the third value based on the identifier. The memory management module further includes an address modification module configured to generate a second address value based on the first address value and the select value.
