Abstract

Patente de Invenção:<B>"MéTODO E APARELHO PARA MANIPULAçãO DE EXCEçõES IMPRECISAS"<D>. São divulgados um método e um aparelho para atualização de um estado arquitetural em uma execução alternada de implementação de sistema com microinstruções múltiplas. De acordo com um aspecto da invenção, um método é proporcionado em que uma macroinstrução é decodificada em primeira e segunda microinstruções. A macroinstrução designa uma operação em fragmentos de dados, a execução das primeira e segunda microinstruções, separadamente, faz com que a operação seja realizada em diferentes partes do fragmento de dados. O método também requer que a primeira microinstrução seja executada independente das segundas microinstruções (por exemplo, em um momento diferente) e que seja detectado que a referida segunda microinstrução não causará quaisquer exceções não - recuperáveis. Os resultados da primeira microinstrução são, então, usados para atualizar o estado arquitetural em um ciclo de relógio antes da referida segunda microisntrução.
