Abstract
A digital data system includes a circuit for controlling data transfer between a byte wide device, such as a SCSI disk drive, to a four byte wide pathway such as VME bus. The control circuit effects selective control of data transfer of an odd byte, an even byte, a short word (two parallel bytes), or a long word (four parallel bytes). The control circuit includes a FIFO memory, prefetch registers, MUXs, a VME data register, a state machine and DMA controller.
