Title
(EN) Apparatus, system, and method for accessing persistent files in non-execute-in-place flash memory
(ZH) 存取非XIP快闪存储器中持久文件的装置、系统和方法
Abstract
(EN)
Persistent files stored in non-XIP flash memory are accessed during operation of an electronic device. During execution of application code on the device, the persistent files are accessed using an access directory such as a look-up table. The access directory provides information that allows an application or other software code running on the processor of the device to locate and access a persistent file within a non-XIP flash memory device where the non-XIP flash memory device may include bad blocks. During creation of the access directory, locations of the bad blocks in the device are identified and recorded. Files are accessed from the non-XIP flash memory device by reading from file start locations identified in the access directory while accounting for bad blocks identified in the bad block data of the access directory.

在电子装置的操作期间,对存储在非XIP快闪存储器中的持久文件进行存取。在执行该装置上的应用代码时,使用例如查找表的存取目录对持久文件进行存取。存取目录提供允许在装置的处理器上运行的应用程序或其它软件代码对非XIP快闪存储器装置内的持久文件进行定位和存取的信息,其中所述非XIP快闪存储器装置可包括坏块。在创建存取目录时,识别并记录装置内的坏块位置。通过从存取目录中标识的文件起始位置读取文件并说明存取目录的坏块数据中识别的坏块,从非XIP快闪存储器装置中存取文件。
