Abstract
An Input/Output Module (IOM) interfacing multiple computers attached to a dual system bus. The IOM provides an interbus module which interfaces the dual system bus to a sub-requestor bus connecting multiple sub-requestor modules. The sub-requestor modules control a plurality of interface adaptors permitting data transfers to/from a variety of peripherals using different data protocols and clock rates. The requirements for the main host processors and memories in a computer system would be unduly burdensome were it not for the relief from these overhead operations by the input/output module which provides the tailoring of data transfer capability to and from a multiplicity of peripherals having many different types of protocols and clock rates.
