NvM在AUTOSAR中的層次結(jié)構(gòu)

名稱

描述

Basic Storage Object

Basic Storage Object是一個(gè)最小的NVRAM block，多個(gè)Basic Storage Objects可以組成一個(gè)NVRAM Block。

NVRAM Block

NVRAM Block是管理和存儲(chǔ) NV Block所需的整個(gè)結(jié)構(gòu)

NV data

要存儲(chǔ)在Non-Volatile memory的數(shù)據(jù)

Block Management Type

這個(gè)是NVRAM Block的類型，它取決于強(qiáng)制/可選Basic Storage Object中 NVRAM Block的（可配置的）單獨(dú)組成以及該 NVRAM 塊的后續(xù)處理。

RAM Block

屬于Basic Storage Object，它是NVRAM Block的一部分，常駐于RAM空間。

ROM Block

屬于Basic Storage Object，它是NVRAM Block的一部分（可選的），常駐于ROM空間。

NV Block

屬于Basic Storage Object，它是NVRAM Block的一部分（必選的），常駐于NV空間。

NV Block Header

如果Static Block ID是enable的，這個(gè)作為附加信息包含在NV Block中。

Administrative Block

屬于Basic Storage Object，它常駐于RAM，是NVRAM Block必選部分。
