Abstract
PowerPC external control instructions are utilized to pass a translated address to a transfer engine located in the system memory controller, together with previously transferred parameters into control registers within the memory controller. An accelerated data movement is accomplished between system memory and an input/output device with a minimum of processor overhead and bus bandwidth utilization. This method is useful for transferring large amounts of data between memory and such devices as graphics adapters or multimedia devices.
