Abstract: This invention relates to personal computers, and more particularly to a personal computer using a FIFO registers for data transfer as illustrated by a bus master device in the form of a small computer systems interface (SCSI) controller for controlling data transfer with storage memory devices such as fixed or removable media electromagnetic storage devices. In the practice of this invention, the efficiency of a system having a plurality of bus master devices is enhanced by providing for a programmable threshold fill condition for a FIFO register before arbitration for bus control occurs. Thus the invention provides an approach to maximizing the efficiency of data transfer where FIFO registers are used.
