简介 (Introduction)

内存抽象接口（MemIf）将从底层FEE或EA模块的数量中抽象出来，并在一个统一的线性地址空间上为上层提供一个虚拟分段，即允许NVRAM管理器访问几个内存抽象模块。

The memory abstraction interface (MemIf) abstracts away the number of underlying FEE or EA modules and provides an upper layer with a virtual segmentation over a unified linear address space, allowing the NVRAM manager to access several memory abstraction modules.

AUTOSAR中的存储协议栈处于BSW基础软件层，包括存储器驱动层、存储器硬件抽象层、存储器服务层。存储协议栈软件是用来为整车电子模块（ECU）存储非易失性或者标定数据定义一套统一访问内存的服务软件。

The storage protocol stack in AUTOSAR is located in the BSW Basic Software layer and includes the memory driver layer, memory hardware abstraction layer, and memory service layer. The storage protocol stack software defines a unified service software for accessing memory to store non-volatile or calibration data for the entire vehicle's electronic modules (ECUs).

MemIf功能 (MemIf Function)

MemIf功能介绍 (MemIf Function Introduction)

存储协议栈软件架构图中的最底层灰色部分为存储栈的硬件控制器，这部分功能属于ECU的内部或外部FLASH（EEPROM）存储器设备，并实现存储栈FLASH或EEPROM数据存储单元的物理存储介质；存储栈软件架构图中的第二层粉红色部分为微控制器抽象层（MCAL），这部分功能属于ECU的内部或外部FLASH（EEPROM）存储器设备抽象层，并实现存储栈FLASH或EEPROM存储设备的硬件控制驱动程序，即直接操作硬件控制器寄存器，提供写入、读取、擦除、比较等API接口给上层FEE或EA模块使用；存储栈软件架构图中的第三层淡绿色部分为存储器抽象层（FEE和EA），这部分功能属于ECU的内部或外部FLASH（EEPROM）存储器设备抽象层，并实现存储栈的存储设备抽象和接口映射，即存储栈抽象层不涉及任何硬件的操作，只是申请对内存进行行为操作的请求与内存地址映射，由MemIf接口层提供统一FLASH或EEPROM内存写入、读取、擦除、比较等接口给存储栈服务层使用，存储栈中所有的状态控制类、操作结果等数据类型也是由MemIf接口层来实现；存储栈软件架构图中的最顶层淡蓝色部分为非易失性存储管理部分，这部分功能属于ECU存储栈非易失性数据管理与维护，并实现存储栈中单个Block或多个Block的数据写入、读取、擦除等API接口，便于存储栈用户使用和对非易失性数据的需求和管理。

The gray part at the lowest layer of the storage protocol stack software architecture diagram is the hardware controller of the storage stack, which belongs to the internal or external Flash (EEPROM) memory devices of ECU and implements the physical storage medium for Flash or EEPROM data storage units; The second layer, light pink in color, represents the Microcontroller Abstraction Layer (MCAL) of the storage stack, which also belongs to the abstract layer of the internal or external Flash (EEPROM) memory devices of ECU, and realizes the hardware control driver programs for storage stack Flash or EEPROM storage devices, i.e., directly operating on the registers of the hardware controller, providing write, read, erase, compare APIs interfaces for the upper-level FEE or EA modules to use; The third layer, light green in color, represents the Memory Abstraction Layer (FEE and EA) of the storage stack, which also belongs to the abstract layer of the internal or external Flash (EEPROM) memory devices of ECU, and realizes the abstraction and interface mapping of storage devices for the storage stack. The Storage Stack Abstraction Layer does not involve any hardware operations; it only requests permission to perform behavior actions on memory and address mappings, with MemIf Interface Layer providing unified FLASH or EEPROM memory write, read, erase, compare interfaces for use by the storage stack service layer. All state control classes, operation results, and data types in the storage stack are also realized by the MemIf Interface Layer; The light blue part at the topmost layer of the storage protocol stack software architecture diagram represents the Non-Volatile Memory Management section, which belongs to the non-volatile data management and maintenance of ECU's storage stack. It realizes APIs for data write, read, erase, etc., in single or multiple blocks within the storage stack, facilitating use by storage stack users and managing their needs and requirements for non-volatile data.

MemIf功能实现 (MemIf Functional Implementation)

MemIf对FLASH或EEPROM存储器的抽象，属于硬件无关层。其作用为：

Abstraction of MEMIf for FLASH or EEPROM memory, belonging to the hardware-agnostic layer. Its function is:

• 允许NVM访问多个存储抽象模块（Fee/Ea）

Allow NVM access to multiple storage abstraction modules (Fee/Ea)

• 对上层提供统一线性地址空间的虚拟分段

Provide a uniform linear address space for upper layers through virtual segments

• 该模块的API都映射到下层存储抽象模块的API（Fee/Ea）

The APIs of this module map to the APIs of the underlying storage abstraction module (Fee/Ea).

• 抽象ROM的功能，无论使用Flash还是EEPROM，从MemIf模块开始指令没有任何区别，代码通用，彻底脱离硬件

The abstract ROM functionality is identical whether using Flash or EEPROM; instructions starting from the MemIf module are no different, and the code is generic, completely hardware-independent.

• 抽象ROM的设备，MemIf模块眼中，ECU只有3种区别：只使用Flash，只使用EEPROM，两者同时使用

Abstract ROM devices, in the eyes of the MemIf module, ECU differ only in three ways: using Flash only, using EEPROM only, or using both.

• 给Flash或者EEPROM或者同时给两者一个Device Index，根据Device Index将NvM模块的指令转发给对应的Fee模块或者Ea模块

Provide a Device Index to Flash or EEPROM, or provide both with a Device Index. According to the Device Index, forward the NvM module commands to the corresponding Fee module or Ea module.

• MemIf模块模块没有初始化，没有配置指针，没有状态指针

The MemIf module is not initialized, no configuration pointer, no status pointer
