ABSTRACT:
To control the transfer of commands and data, an interface device is connected to a host computer by a first data bus, an address bus, and first control-signal lines, and to a disk controller by a second data bus and second, third, and fourth control-signal lines. The interface device includes a first internal bus and a second internal bus interconnected via a first controllable buffer and a second controllable buffer, with the first data bus connected to the second internal bus through a third controllable buffer, and the second data bus to the first internal bus through a fourth controllable buffer. An interface controller is connected to the address bus and to the first, second, and third control-signal lines and, via internal control-signal lines, to the controllable buffers. The third and fourth control-signal lines and an error-signal line are connected to the second internal bus via a fifth controllable buffer.
