Abstract

resumo patente de invenção: "filtro iir de múltiplos estágios e filtragem paralelizada de dados com o mesmo". em algumas modalidades, um filtro de múltiplos estágios cujos estágios de filtro biquad são combinados com latência entre os estágios, um sistema (por exemplo, um codificador ou decodificador de áudio) incluindo tal filtro, e métodos para filtragem biquad de múltiplos estágios. em modalidades típicas, todos os estágios de filtro biquad do filtro operam independentemente para realizar o processamento totalmente paralelizado de dados. em algumas modalidades, o filtro de múltiplos estágios inventivo inclui uma memória de armazenamento, pelo menos dois estágios de filtro biquad, e um controlador acoplado e configurado para determinar uma sequência única de instruções para os estágios de filtro. tipicamente, o filtro de múltiplos estágios é configurado para realizar a filtragem de múltiplos estágios de um bloco de amostras de entrada em um único circuito de processamento com interação através de um índice de amostra, mas sem interação através de um índice de estágio de filtro biquadrático.
