Abstract

"DISPOSITIVO E MéTODO PARA O PROCESSAMENTO DE PELO MENOS DOIS VALORES DE ENTRADA". Para a redução do erro de arredondamento, são fornecidos um primeiro e um segundo valores de entrada não inteiros (260, 262) e um combinador (268), por exemplo, pela adição, no estado não inteiro para obter um valor de resultado não inteiro que é arredondado e somado (269) a um terceiro valor de entrada. Assim, o erro de arredondamento pode ser reduzido em uma interface entre duas rotações divididas em etapas de lifting ou entre uma primeira rotação dividida em etapas de lifting e uma primeira etapa de lifting de uma subseqüente seqüência de lifting multidimensional.
