ABSTRACT:
A method and apparatus for transferring data between two data processors includes transferring a data byte from the first processor to a latch member, setting a flip-flop circuit which generates an interrupt signal to the second processor enabling the second processor to transfer the data byte from the latch member to a RAM memory unit associated with the second processor. The second processor resets the flip-flop circuit which outputs a signal to the first processor enabling the first processor to transfer another data byte to the latch member. Steering address bits associated with each of the processors are used to provide control signals to select the storage member in which the data bytes are to be transferred. A second flip-flop circuit associated with the second processor allows the second processor to transfer data to the first processor in the same manner.
