IC647SRB001 GE 质保一年

从开发界面来看，桌面操作系统试图给开发提供一个“黑箱”，让开发人员通过一系列标准的系统调用来使用操作系统中的功能，而嵌入式试图为开发提供一个“白箱”，让开发人员可以自主控制系统的所有资源。

桌面操作系统的研究开发指导思想是尽可能在不改变自身的前提下具有广泛的适应性。也就是说：不论应用环境怎么变化，好都不要对自身内部产生什么影响，也不要求自身做太多的变化。反过来，应用于嵌入式环境的RTOS，在研发的时候就必须立足于改变自身、开放自身，让开发人员可以根据硬件环境和应用环境的不同而对操作系统进行灵活的裁剪和配置，因为对于任何一个具体的嵌入式设备，它的功能是确定的，因此只要从原有操作系统中把这个特定应用所需的功能拿进来即可。
