Abstract: A method of providing more efficient and streamlined data access to DRAM storage medium by all of multiple processors within a system on a chip (SoC) requires every processor to send use-of-bus request.

When the request is for non-local access (that is, to DRAM within the storage medium which is reserved for another processor), the processor reads or writes to the “foreign” address in the storage medium through its own arbiter, its own memory controller, and its own DMA controller. A data access system is also disclosed.
