Abstract

"DISPOSIçãO DE MICROPROCESSADOR COM CODIFICAçãO". A invenção refere-se a uma disposição de microprocessador que abrange um coletor de dados (4), para a transmissão de dados entre unidades funcionais (1, 2, 3). Cada unidade contém no lado do coletor, um dispositivo de codificação e de decodificação (11, 21, 31), que são comandados por um gerador de valores aleatórios (6) de forma síncrona. A disposição possibilita uma segurança de escuta relativamente alta dos dados transmitidos através do coletor de dados, com dispêndio de ligação adicional substituível.
