Switching to original code comparison of modifiable code for translated code validity when frequency of detecting memory overwrites exceeds threshold
摘要：
A method of translating instructions from a target instruction set to a host instruction set. In one embodiment, a plurality of first target instructions is translated into a plurality of first host instructions. After the translation, it is determined whether the plurality of first target instructions has changed. A copy of a second plurality of target instructions is stored and compared with the plurality of first target instructions if the determining slows the operation of the computer system. After comparing, the plurality of first host instructions is invalidated if there is a mismatch. According to one embodiment, the storing, the comparing and the invaliding is initiated when the determining indicates that a page contains at least one change to the plurality of first target instructions. In one embodiment, the determining is by examining a bit indicator associated with a memory location of the plurality of first target instructions.
摘要（中）：

将指令从目标指令集转换为主机指令集的方法。 在一个实施例中，多个第一目标指令被转换成多个第一主机指令。 在翻译之后，确定多个第一目标指令是否已改变。 如果确定减慢了计算机系统的操作，则存储第二多个目标指令的副本并与多个第一目标指令进行比较。 在比较之后，如果存在不匹配，则多个第一主机指令被无效。 根据一个实施例，当确定指示页面包含对多个第一目标指令的至少一个改变时，开始存储，比较和无效。 在一个实施例中，确定是通过检查与多个第一目标指令的存储器位置相关联的比特指示符。
