X86处理器价格高,一旦出现故障会导致电子产品出现各种异常且定位困难。提出一种基于CPLD的X86系统硬件检测卡,当X86处理器出现故障时,将通往IO 80端口地址的上电自检数据通过CPLD转成串行数据输出。该方法不需要PCI硬件插槽,节省PCB空间840 mm2,不需要外置硬件debug卡,降低硬件成本,提高X86系统故障定位效率,方案可实施性强,尤其在高密度电子产品上具有很强的推广价值。

The X86 processor is expensive,its failure will lead to various abnormal phenomenon,and it is difficult to solve. This paper proposes a X86 system hardware detection card based on CPLD,it converts parallel data into serial data through CPLD when the X86 processor is failure. The method need not be additional PCI slot,it saves PCB board space 840 mm2,and need not set the hardware debug card,so it reduces the hardware cost,and improves the fault location X86 system efficiency. The project implementation is especially strong in high density electronical product.
