Abstract
A data processing apparatus which can copy necessary data without imposing a burden on a CPU when broadcasting specific data is realized. A data processing apparatus includes a reception FIFO memory which temporarily stores received data sequentially; a buffer management unit which reads out the received data stored in the reception FIFO memory, discriminates whether or not a plurality of the same data are required for transferring the received data, and searches a plurality of buffer memory areas that are different from each other when the plurality of the same data are required; and a DMA (Direct Memory Access) control circuit which writes the received data read from the reception FIFO memory into each of buffer memory areas designated by the buffer management unit.
