    • A method of establishing pre-fetch control information from an executable code is described. The method comprises inspecting the executable code to find one or more instructions corresponding to an unconditional change in program flow during an execution of the executable code when the executable code is retrieved from a non-volatile memory [NVM] comprising a plurality of NVM lines. For each unconditional change of flow instruction in the executable code, the method comprises establishing a NVM line address of the NVM line containing said unconditional change of flow instruction; establishing a destination address associated with the unconditional change of flow instruction; determining whether the destination address is in an address range corresponding to a NVM-pre-fetch starting from said NVM line address; establishing a pre-fetch flag indicating whether the destination address is in the address range corresponding to a NVM-pre-fetch starting from said NVM line address; and recording the pre-fetch flag in a pre-fetch control information record. Also, a NVM controller, a device, a processor system and computer program products are described.
    • 描述了从可执行代码建立预取控制信息的方法。 该方法包括:当从包括多个NVM线的非易失性存储器(NVM)检索可执行代码时,检查可执行代码以查找在执行可执行代码期间对应于程序流的无条件改变的一个或多个指令。 对于可执行代码中的每个无条件改变流程指令,该方法包括建立包含所述无条件流动指令改变的NVM行的NVM行地址; 建立与无条件改变流程指令相关联的目标地址; 确定所述目的地址是否处于从所述NVM行地址开始的NVM预取对应的地址范围内; 建立指示目的地地址是否在与从NVM线地址开始的NVM预取相对应的地址范围内的预取标志; 并将预取标志记录在预取控制信息记录中。 此外,还描述了NVM控制器,设备,处理器系统和计算机程序产品。
