Abstract

"MéTODO E APARELHO PARA CORRIGIR CODIGOS E DADOS RESIDENTES EM UMA MEMóRIA". Um método e um aparelho para aplicar correções a um código ou dado residente em um dispositivo de memória não-volátil são ilustrados. Um código residente em uma primeira localização na memória não-volátil pode ser substituído por códigos residentes em uma segunda localização no mapa de memória. O dispositivo de correção compara um primeiro endereço de um primeiro código com um endereço identificado por uma instrução de pré-aquisição. Se o primeiro endereço combinar com o endereço identificado pela instrução de pré-aquisição, o cancelamento da pré-aquisição é emitido para facilitar a substituição do código ruim residente no primeiro endereço por um código bom. O código bom pode ser apontado por um vetor na tabela de vetores onde o endereço dos vetores é dinamicamente carregado dentro de um contador de programa.
