Abstract
A bridge capable of preventing data inconsistency is provided, in which a first master device outputs a flush request, a buffering unit buffers data or instructions, and a flush request control circuit records a buffer write pointer of the buffer according to the flush request and outputs a flush acknowledgement signal to the first master device in response of that a buffer read pointer of the buffering unit is identical to the recorded buffer write pointer.
