Abstract The improvements in throughput expected from direct‐memory‐access channels are not realized with simple input/output routines. For output operations, the improvements can be realized through the provision of a separate data buffer area in memory that may be accessed by the peripheral while the primary buffer area is being manipulated by the program. The method may be extended to peripherals that require error checking after output.
