METHOD AND APPARATUS FOR PROVIDING ACCURATE AND COMPLETECOMMUNICATION BETWEEN DIFFERENT BUS ARCHITECTURESIN AN INFORMATION HANDLING SYSTEMABSTRACTThe present invention provides hardware logic within a hostbridge that connects a CPU local bus to a peripheral bus thatdetermines if data to be transmitted on the CPU local bus isnon-contiguous and, if so, substitutes contiguous data for thenon-contiguous data to ensure that the CPU local bus does notmalfunction. Simultaneously, the inventive hardware translatesdata transfers between a peripheral bus that is limited by itsarchitecture to data strings of a standard length and a CPUlocal bus that permits dynamic bus sizing.
