ABSTRACT:
An I/O subsystem uses a peripheral-controller for handling data transfer operations between a host computer and a plurality of peripheral terminals. The peripheral controller is made of (a) a universal processor, which generates instructions for executing data transfer operations, and (b) an application dependent logic module which particularly adapts the instructions to each peripheral terminal connected to the system. Upon recognition of the use of addresses for slow memories, slow registers or "slow devices", control logic in the application dependent logic module controls the clocking in the universal processor to slow data transfer rates for data being placed in or removed from the "slow devices".
