A multiple bus interface is provided for connection to the bus of a data processing device. It includes a common interface adapted for connection to any one of several bus architectures for operation therewith. The interface adapter includes a control interface for accepting control signals from the bus of the data processing device, an address interface for accepting address signals from the data processing device, and a data interface for accepting data signals from the data processing device. A bus identifier is provided for identifying the bus architecture of the data processing device as will as a bus protocol decoder responsive to the bus identifer. The decoder derives its input from the control interface and is adapted to produce as an output standardized local control signals derived from the data processing bus control signals for sue by a local functional device to be accessed by the data processing device. <IMAGE> |
