Abstract

"CIRCUITO PARA DETECTAR A TEMPORIZAçãO DE UMA PLURALIDADE DE BITS DE DADOS DENTRO DE UM FLUXO DE DADOS ASSìNCRONO, PROCESSO PARA PROCESSAR UM FLUXO DE DADOS ASSìNCRONO, E, SISTEMA PARA DETECTAR A VELOCIDADE DE UM FLUXO DE DADOS ASSìNCRONO". A velocidade de comunicação serial assíncrona é detectada determinando uma duração de um bit de dados dentro de um fluxo de dados assíncronos. A duração do bit de dados é usada para gerar uma freq³ência de cronometragem. A freq³ência de cronometragem é usada para referir em tempo dados do fluxo de dados assíncronos em um registro. Os dados cronometrados são processados de acordo com uma indicação de erro.
