ABSTRACT:
A data processing system wherein one of a number of central processing units writes a command for data transfer to it from a second processor over a data bus to a common memory and a digital code to an interrupt table, the code indicating interruption of the second processor. Decoding apparatus responsive to the digital code causes the second central processor to read the command for data transfer from the memory and transfer data to the first central processor.
