Abstract
The object of the invention is to enhance data transmission efficiency by considering a clock frequency, a data transmission method and a data storage method. To achieve the object, an information processing unit according to the invention is provided with a bus on which a data transmission signal is transmitted from the side of a master (a transmission source) to the side of a slave (a transmission destination), another bus on which a data transmission completion signal is transmitted from the slave's side to the master's side, the other bus on which a data signal is transmitted from the master's side to the slave's side, a functional block for converting a protocol on the master's side to a protocol on the slave's side, another functional block for converting the protocol on the slave's side to the protocol on the master's side, registers controlled by a clock on the master's side, registers controlled by a clock on the slave's side, buses for converting from the clock on the master's side to the clock on the slave's side and a bus for converting from the clock on the slave's side to the clock on the master's side.
