Abstract:
A method for prefetching data in a bus system is provided. First, according to an address signal from a master, a prefetching address generator generates a prefetching address signal and transfers it to a first select circuit. In response to a signal from the master indicates that the address is related to the previous address and the control signal is identical to the previous transfer, or in response to a signal from the master indicates that the address and control signals are unrelated to the previous transfer but is matched to a hit logic, a prefetching controller directs the first select circuit to transfer the prefetching address signal to a slave. And the prefetching controller also directs a second select circuit to transfer the prefetched data which is corresponding to the prefetching address signal from the slave to a master.
