Abstract
são revelados métodos e equipamentos para impedir violações de memória. em um aspecto, uma unidade de busca acessa, a partir de um preditor de desvio de um processador, um indicador de desambiguação associado com um bloco de instruções de um programa a ser executado pelo processador, e busca, a partir de uma cache de instruções, o bloco de instruções. o processador executa instruções de carregamento e/ou instruções de armazenamento no bloco de instruções baseado no indicador de desambiguação indicando se as instruções de carregamento e/ou as instruções de armazenamento no bloco de instruções podem ou não desviar outras instruções do programa ou serem desviadas por outras instruções do programa.
