Abstract
"IMPLEMENTAçãO DE CONTROLE DE ACESSO à MEMóRIA UTILIZANDO OTIMIZAçõES". São revelados mecanismo que podem permitir certos algoritmos de controle de acesso à memória serem implementados de forma eficiente. Quando o controle de acesso à memória é baseado em se controlar as alterações junto a um mapa de tradução de endereço (ou conjunto de mapas), pode ser necessário determinar se uma alteração particular do mapa permitiria que a memória fosse acessada de um modo não permitido. Certos dados a cerca do mapa podem ser colocados em memória cache de modo a permitir que a determinação seja feita de forma mais eficiente do que executando-se uma avaliação de todo o mapa.
