ABSTRACT:
An interface control unit is included in a digital computer system for controlling the transfer of sets of characters between a main memory and a peripheral unit of the mass storage type. The information is transferred in parallel by the interface control unit at the speed of the main memory, independent of the speed of the mass storage. A buffer memory adapted to store a pair of characters is provided; it alternately operates by writing a first and at the same time by reading a second set. The first character of the burst is always transferred to the memory by the microprocessor and the following by the interface control unit.
