In a computer which translates instructions from a target instruction set to a host instruction set, a method and apparatus for determining if writes to a memory page are directed to target instructions which have been translated to host instructions, the method including the steps of: detecting a physically- addressed write to a physical memory page storing target instructions which have been translated to host instructions, comprising the steps of: storing in physically-addressable memory an indicator for each physical memory page that stores target instructions which have been translated to host instructions, and detecting the indicator when a write is attempted to each such physical memory page; detecting whether a sub-area of the physical memory page to which the write is addressed stores target instructions which have been translated; and invalidating host instructions translated from physically-addressed target instructions when a write is attempted to the sub-areas of physical system memory.
L'invention concerne un procédé permettant de déterminer si les inscriptions dans une souspage de mémoire sont dirigées vers des instructions cibles qui ont été traduites en instructions hôtes dans un ordinateur qui traduit des instructions à partir d'un ensemble d'instructions cible vers un ensemble d'instructions hôte. Le procédé consiste à détecter une inscription dans une sous-page de mémoire stockant des instructions cible ayant été traduites en instructions hôte, à détecter si une sous-zone de la page mémoire à laquelle est adressée l'inscription stocke des instructions cible qui ont été traduites, et à invalider les instructions hôte traduites des instructions cible adressées.
