Abstract

Patente de Invenção: "MéTODO PARA O GERENCIAMENTO DE DADOS RECEBIDOS POR MEIO DE UM BARRAMENTO DE DADOS E APARELHO PARA REALIZAR O MéTODO". O formato da transmissão de pacotes de dados isocrónicos por meio do barramento IEEE 1394 é definido no Padrão IEC 61883. Neste caso, é possível usar um modo de operação no qual o mesmo número de blocos de dados (DBO-DB7) é sempre transmitido em um pacote de barramento. Neste caso, o gerenciamento de memória é extremamente simples e os limites de pacote de fonte de dados podem facilmente ser determinados. No entanto, o padrão IEC 61883 também deixa aberta a possibilidade de transmitir um número variável de blocos de dados (DBO-DB7) no contexto de transmissão de dados isocrónicos com a ajuda de pacotes de barramento. Neste caso, no entanto, determinar subsequentemente os limites de pacote de fonte de dados apresenta um problema. A invenção específica uma solução, favorável em termos de despesa, quanto a como os limites de pacote de fonte de dados podem facilmente ser reconstruído. é baseado essencialmente em contagem de n módulos dos blocos de dados (DBO-DB7).
