二、概念
1、POSIX标准
可移植操作系统接口(英语:Portable Operating System Interface,缩写为POSIX)是IEEE为要在各种UNIX操作系统上运行软件,而定义API的一系列互相关联的标准的总称。
目前广泛使用的 POSIX 标准是 1003.1 标准,全称为IEEE Std 1003.1(缩写写法为 POSIX.1)。
2、IEEE 1003.13
IEEE 1003.13是POSIX 针对嵌入式领域制定的标准【实时规范 (reatime profiles)】,该标准是由 IEEE Std 1003.1 筛选而来,因此是其子集。
POSIX 为了提供不同层级的RTOS能力,IEEE Std. 1003.13 定义了四个子集:
- Minimal:最小嵌入式子集规范 —— PSE51
- Controller:工业控制器子集规范 —— PSE52
- Dedicated:较大规模的嵌入式系统子集规范 —— PSE53
- Multi-Purpose:具有实时性要求的大规模通用系统子集规范 —— PSE54
3、规范划分
主要根据Module 和_POSIX_开头宏来进行细化
