Design and Realization of HT Interconnection and Memory Fault Diagnosis Method for loongson-3 Mainboard

The loongson-3 processor is widely used in the field of safety and reliability. This type of motherboard has a high density of devices, a high degree of board mounting, and a difficulty in fault detection; it is necessary to strengthen the device self-detection and fault self-diagnosis design while ensuring high hardware reliability; based on loongson 3 mainboard, there are two common types of faults, computer motherboard HyperTransport(HT) interconnection and memory errors, which provide a software-assisted fault diagnosis and reliability enhancement method, which provides an effective software-assisted method for locating faults for factory maintenance support; Experiments show this method can quickly and efficiently locate the failure of the loongson-3 motherboard, which improves the efficiency of maintenance support.
