Abstract
"APARELHO PARA TRANSFERIR DADOS, SISTEMA DE TRANSFERêNCIA DE DADOS, E, MéTODO PARA TRANSFERIR DADOS EM UM SISTEMA DE TRANSFERêNCIA DE DADOS". Quando dados são transferidos de uma CPU hospedeira (14) para um processador de som (24) que reproduz sons de música em uma base de tempo real, a carga na CPU hospedeira (14) é grandemente reduzida. Na transferência de dados de som de música da CPU hospedeira (14) como uma fonte de transferência, a CPU hospedeira (14) e um DMAC (44) operam um tamanho de dados de 2560 palavras que é maior do que a capacidade de armazenamento de 256 palavras de memórias temporárias (41, 42). Depois que dados de som de música foram transferidos para uma das memórias temporárias (41) até que se torne cheia de dados, o processador de som (24) suspende temporariamente a transferência dos dados. Quando dados de som de música na outra memória temporária (42) são reproduzidos pelo processador de som (24) e a memória temporária (42) se torna vazia, o processador de som (24) coloca a memória temporária vazia (42) como uma memória de destino de transferência, cancela a suspensão temporária da transferência dos dados, e recomeça a transferência dos dados para a memória temporária vazia (42).
