The process involves applying a physical address to an address bus, and delivering a signal having a value to a direct memory access controller (6). A signal with a value, different from the former, is delivered to the bus entities via drive lines. When the signal with the former value is delivered, the controller selects a register from source and destination registers and stores in it the address read on the bus. The physical address is translated from a virtual address by a memory management unit (MMU) (3). An independent claim is also included for a system on chip. |
