Abstract: PURPOSE: To provide a digital processor which is constituted as an integrated circuit on a single substrate for housing a plurality of peripheral buses. CONSTITUTION: A device 10 positioned on a single substrate 12 contains a computer processor 14, a connection 16 for S-bus, and a supporting peripheral device 18 incorporated with an S-bus interface circuit 20, and a bus master supporting circuit 22. A connection 24 for M-bus is related to a dynamic random access memory (RAM) controller 28, a random access memory (RAM), an M-bus supporting peripheral device 26 containing a controller 30. An S-bus supporting peripheral device 34 is correlated with an X-bus connection 32 and contains an X-bus interface 36.
