<p>An entertainment device comprises a peripheral device (130) and a control device (120) for controlling the peripheral device. ?The peripheral device (130) and the control device (120) are connected together by an address bus (A[27:0] and a data bus (D[15:0]). ? Upon receiving a DMA acknowledgment signal (DMA ACK2) from the control device (120), the peripheral device (130) performs 32 bit DMA transfer using lower 16 bits (Addr [15:0]) of the address bus and the data bus (Data [15:0]) while the DMA acknowledgment signal (DMA ACK2) is asserted.</p> |
