PROBLEM TO BE SOLVED: To improve radio communication throughput by eliminating an overhead about data transfer in a radio communication processor while suppressing power consumption by suppressing a processing load of a device side main CPU. SOLUTION: In the radio communication processor 1, when transferring an Ethernet (R) packet to a memory 13, a DMA (direct memory access) controller 12 notifies a local CPU 14 of a transfer end to make the local CPU 14 prepare a radio header and controls data of the Ethernet (R) packet transferred to the memory 13 and the radio header prepared by the local CPU 14 so as to be inputted to an FIFO 16 when the transfer of the header of the Ethernet (R) packet ends.
