Abstract
PURPOSE: To preferentially carry out the data transmission in which the speed is requested and perform the interrupt processing with flexibility by and alotting the functions for hardware and firmware in the case of connecting the input and output devices different in bus interface to the information processing system.
CONSTITUTION: The adpter 21 is an interface controller of the bus of a machine type controlled by the microcomputer and the other bus of the other machine type and mainly comprises a control portion μ CPU 22 constituting a base of the adapter, ROM23 for accommodating the firmware therein, command from CPU, RAM 24 for retracting the interruption from IO, bus control portion BCA 25 for carrying out the dialog with CPU, and bus control portion BCN 26 for carrying out the bus dialog with IO.
