Abstract
"LFSR DE BAIXA POTêNCIA" FSR de baixa potência compreendendo um conjunto ordenado de etapas de registrador incluindo meios de memória (1 - 7), caracterizado pelo fato dos meios de habilitação (F1 - F7, N1 - N7), habilitarem um único meio de memória (1 - 7) a cada operação de deslocamento. Cada etapa de registro compreende um meio de memória de baixa potência (7) consumindo um mínimo de energia quando está desabilitado, meios de retroalimentação (E7), um seu terminal de saída sendo conectado a um terminal de entrada do meio de memória (7), o meio de retroalimentação (E7) possuíndo primeiro e segundo terminais de entrada conectados a um terminal de saída (dado 7) do meio de memória (7) e um terminal de saída (dado2) de um segundo meio de memória subseq³ente (2), respectivamente, no conjunto. O terminal de saída (dado1 - dado7) de cada meio de memória (1 - 7) sendo conectado ao meio de seleção (M1), selecionando em cada operação de deslocamento o terminal de saída (dado1) de um primeiro meio de memória subseq³ente (1) em seguida ao corrente meio de memória (7) sendo habilitado na corrente operação de deslocamento.
