Abstract
A bridge system includes a request device, connected to a first bus; a target device, connected to a second bus; and a bridge, communicated with the first bus and the second bus, and the bridge has a buffer, wherein when the request device asks the bridge for reading data of a target address from the target device, a transaction is started, and the bridge asks the target device to transfer data of the target address and following addresses, and then the target device retrieves and transfers the data of the target address and following addresses to the bridge, that is stored in the buffer and then transferred to the request device in turn, and wherein as amount of transferred data to the request device reaches a threshold, the bridge continuously asks data of a following address of the target device before the transaction is finished.
