在嵌入式系统中会有一块处理器芯片，此外，还有其它的芯片作为外部设备（后面简称外设），这些芯片与处理器协作实现产品的功能。复杂的产品往往是由大量的芯片组成的。那么不可避免的是我们需要将所有的外设与处理器进行相连，为简单的是将所有的外设都采用独立（注意是独立）的信号线连接至处理器，这样的好处是容易理解，但问题是：不可行。因为处理器芯片需要引出太多的线了，从芯片的生产和产品的生产角度来看都不实际。加之，处理器（在此我们假设处理器是单核的，而不是多核的）处理事务在微观上是串行的，也就是说在某一时刻如果要对外设进行读写操作，那只可能是对大量外设中的一个进行，即多个外设不可能在微观上被处理器同时访问。需要注意的是，这里提出了微观这一概念，这是为了区别于宏观。从宏观上来讲，一个处理器中可以有多个任务同时运行，但这些任务在微观上却是一个一个运行的（后面会用串行来描述这里所说的“一个一个”），多任务的串行运行实现是由操作系统扮演着重要的角色来实现的。回到我们的话题，即然将每个外设采用独立的信号线连到处理器不可行，且处理器在单一时间内只会对一个外设进行访问，那我们能不能采用共享的信号线将所有的芯片连在一起呢？这就是总线概念的由来。通俗的说，如果我们周围有十个家庭，为了让这十个家庭每两个之间都能往来，我们并不需要为每两个家庭修一条单独（注意是单独）的路（如果这样，要修45条路），而是可以修一条大路，然后，每个家都与大路相连。
