前面的文章介绍过,PCIe总线除了有Base Spec,还有关于PCIe卡的Spec(又称为CEM Spec,全称为PCI Express Card Electromechanical Specification)。该Spec主要内容包括辅助信号(Auxiliary Signals)、热插拔(Add-in Card Hot Insertion and Removal)、电源传递(Power Delivery)、PCIe卡电气规范(Add-in Card Electrical Budget)...
值得注意的是,在实现热拔插功能时,Add-in Card需要使用“长短针”结构。如图4-3 所示,PRSNT1#和PRSNT2#信号使用的金手指长度是其他信号的一半。因此当PCIe设备插入插槽时,PRSNT1#和PRSNT2#信号在其他金手指与PCIe 插槽完全接触,并经过一段延时后,才能与插槽完全接触;当PCIe 设备从PCIe 插槽中拔出时,这两个信号...
处理器主板的热插拔控制逻辑将捕获这个“高电平”,得知Add-In卡已经被拔出,从而触发系统软件进行相应地处理。 不同的处理器系统处理PCIe设备热拔插的过程并不相同,在一个实际的处理器系统中,热拔插设备的实现也远比图4‑3中的示例复杂得多。值得注意的是,在实现热拔插功能时,Add-inCard需要使用“长短针”结构。

PCI clock:spec中规定,所有的PCI设备必须支持0M-33MHz范围内的PCI操作,为了低功耗和静态调式能力。集成在板子上的部件可能会设计为工作在固定的时钟频率,add-in card上的设备必须支持从0-33MHZ可变的工作频率。因为card可能工作在不同的平台。 Address phase:1个PCI clock ...
