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.
Cette invention se rapporte à un dispositif de divertissement comprenant un périphérique (130) et une commande (120) servant à commander le périphérique. Le périphérique (130) et la commande (120) sont connectés l'un à l'autre par un bus d'adresses (A[27:0]) et par un bus de données (D[15:0]). A la réception d'un signal de confirmation de réception DMA (DMA ACK2) en provenance de la commande (120), le périphérique (130) effectue un transfert DMA 32 bits à l'aide des 16 bits inférieurs (Addr [15:0]) du bus d'adresses et du bus de données (données [15:0]), pendant que le signal de confirmation de réception DMA (DMA-ACK2) est confirmé.
