随着信息家电的普及，智能化、网络化将会无所不在，所有这些都离不开嵌入式软件，而在嵌入式软件只中最核心的莫过于RTOS（Real Time Operating System，实时操作系统）。我们都非常熟悉Windows这样的操作系统，但却不一定熟悉嵌入式系统中常用的RTOS。如今，微软已经推出了Windows的嵌入式版本——Windows CE。而风靡一时的Linux也在嵌入式系统中扮演着重要角色。这样看来，传统桌面操作系统和嵌入式操作系统的界线似乎也在淡化。事实究竟如何呢？让我们来听听在嵌入式软件领域颇有造诣的专家是怎么说的。
用于嵌入式环境的操作系统RTOS与桌面操作系统有很多本质的不同。这些不同的特性导致产品开发的不同结果。
嵌入式环境给人的第一印象就是占用空间小。所以，普通的Linux或者Windows操作系统要变成嵌入式操作系统，首先就是要进行裁剪。然而，与桌面环境相比，嵌入式环境对于操作系统系统要求不仅仅是“小”，二者在设计要求上有着本质的不同。这些不同主要体现在可裁剪性、实时性和可靠性等三个方面。
