ABSTRACT:
A bus bridge is connected to a first bus and a second bus. In the bus bridge, an arbiter grants ownership of the first bus to one of a plurality of devices connected to the first bus. A detecting unit detects a read cycle initiated by the device on the first bus to read data from a memory which is also accessible by another device connected to the second bus. A first signaling unit sends a first signal to the arbiter, when the data is not yet transferable to the device when the read cycle is detected. A second signaling unit sends a second signal to the arbiter, when the data becomes transferable to the device. The arbiter deprives the device of the ownership of the first bus upon receipt of the first signal, and withholds from granting the ownership to the device until receipt of the second signal.
