7. 需求规范¶
原文标题：Requirements Specification
This chapter describes all requirements for the selection of the Operating System for the AUTOSAR Adaptive Platform.
8. 功能概述¶
原文标题：Functional Overview
The Operating System is responsible for run-time resource management (including time) for all applications on and within the AUTOSAR Adaptive Platform. This includes not only the Adaptive Applications that run on top of ARA provided by AUTOSAR Adaptive Platform, but also the Functional Clusters that constitute the platform, which are also implemented as applications. The Operating System functions in cooperation with Execution Management which is responsible for platform initialization and the start-up / shut-down of applications.
Note that this Operating System Interface requirement specification contains two different categories. The first category contains the requirements that are directly needed by the Adaptive Applications. The other category contains the ones that are needed by the AUTOSAR Adaptive Platform to realize implementation of Functional Clusters, especially the required mechanisms are difficult or inefficient to be implemented by other software entity than the Operating System. The most notable such Functional Cluster requiring the various Operating System mechanisms is Execution Management.
9. 功能性需求¶
原文标题：Functional Requirements
10. Assumption of Use¶
This section describes execution environment of the AUTOSAR Adaptive Platform that is directly or indirectly used to run the Adaptive Applications. This execution environment is not requirements to the AUTOSAR Adaptive Platform in the strict sense, but rather assumptions on properties of Adaptive Application running on the AUTOSAR Adaptive Platform. These assumptions are used to motivate the further requirements, and provide hints for Adaptive Application developers to check if their use cases are covered in this specification document and which specific requirements are derived from those use cases.
The Operating System section defines requirements on the Operating System that Processes can consider fulfilled in order to achieve their function.
11. 通用需求¶
原文标题：General Requirements
This section describes APIs that should be exposed to Processes on the AUTOSAR Adaptive Platform that closely relates to the Operating System functionality. Some libraries in the system may be considered by a Developer to be part of the Operating System without strictly-speaking belonging to it, for example the C++ runtime libraries. For the purpose of this section, the Operating System kernel and its libraries are considered to be a single entity.
POSIX PSE51 Compliance ⌈ | Description: | The minimal OS functionality provided by Adaptive AUTOSAR platform shall be as defined by POSIX PSE51 interface, according to the IEEE1003.13-2003 specification. | |---|---| | Rationale: | The defined functionality of the POSIX profile PSE51 defined by IEEE1003.13 is provided by various off-the-shelf Operating Systems. The PSE51 profile is intended for embedded systems, with a single multi-threaded Process, no file system, no user and group support and only selected options from more general IEEE1003.1 , which is the well-known POSIX standard. PSE51 offers functions for basic synchronized I/O, high-resolution timer, signals, semaphores, shared memory and threads. |
