Abstract

"TABELAS DE PáGINAS SOMBREADAS PARA O CONTROLE DE TRADUçãO DE ENDEREçO". Em um sistema computacional que emprega memória virtual, múltiplas versões de uma dada página são armazenadas: uma versão de diretório, uma versão de tabela, e uma versão de dados. A versão de dados contém os dados que um objeto de software acredita estar armazenados na página. As versões de diretório e de tabela da página contêm versões dos conteúdos da página que foram modificados de alguma maneira de modo a atender uma restrição no mapa de tradução de endereço empregado pelo sistema de endereço virtual. Quando uma página é usada pelo sistema de endereço virtual como um diretório ou tabela, as versões de diretório ou tabela, respectivamente, daquela página são usadas. Quando uma página é o alvo de uma solicitação de leitura, a versão de dados da página é usada.
