Method and apparatus for advanced interprocess communication

A method of controlling access to portions of a physical memory shared among a plurality of processes executing on at least one integrated circuit processor, the method comprising:

• allocating at least one physical buffer for use by a first process of the plurality of processes;
• updating a portion of the at least one physical buffer to store an identifier that identifies the first process;
• and
• storing a transfer request from the first process in a command queue, the transfer request requesting transfer of the at least one physical buffer from the first process to a second process and providing an identifier for the second process.

A memory controller, comprising:

• a command list control unit that receives and stores commands received from a plurality of processes executing on one or more of a plurality of integrated circuit processors within a multi-process device;
• a memory interface unit that retrieves and executes commands from the command list control unit to control allocation of a physical memory buffer from a physical memory, execution of at least one of the commands resulting in a change of a status parameter portion of the physical memory buffer that controls access to the physical memory buffer by the plurality of processes;
• and
• a command unit that receives and stores in a command queue a transfer request from a first process, the transfer request requesting transfer of the at least one physical buffer from the first process to a second process and providing an identifier for the second process.
