Abstract
A bridge circuit adapted to be associated with first and second bus circuits which bridge circuit includes a first path including a plurality of buffers for storing data or addresses being transferred from the second bus to the first bus, a circuit arrangement for detecting that an interrupt of a presenting-running operation has occurred, a circuit arrangement for determining the state of the plurality of buffers when an interrupt occurs, and apparatus for flushing only those buffers of the plurality which were storing data for transfer when the interrupt occurred.
