ABSTRACT:
A multifunctional coupler for connecting a central processing unit of a computer to one or more peripheral devices and for storing at least one portion of an application microprogram that is operative to control transfer of data between a peripheral and the CPU. The coupler includes a mother-board with at least a first and second interface for connecting an output bus of the CPU to at least first and second daughter-boards, respectively. The mother-board also includes a control and command microprocessor that is connected to both the first and second interfaces, a RAM and a first ROM, all connected to an output bus of the microprocessor. The daughter-boards each include a second ROM for storing an application microprogram that includes a first program segment common to all application microprograms run by the microprocessor, that is read from the first ROM, and a second segment that is read from a second ROM, the second segment being specific to a particular application executed by a peripheral.
