Abstract

?sistemas, aparelhos e métodos para execução de especulação de dados? são descritos sistemas, métodos e aparelhos para execução de especulação de dados (dsx). em algumas modalidades, um aparelho de hardware para realizar dsx compreende um decodificador de hardware para decodificar uma instrução, em, que a instrução inclui um código de operação e um operando para armazenar uma porção de um endereço de fallback, hardware de execução para executar a instrução decodificada para iniciar uma região de execução especulativa de dados (dsx) por meio da ativação de hardware de rastreamento de dsx para rastrear acessos de memória especulativa e para detectar violações de ordenamento na região de dsx, e armazenar o endereço de fallback.
