Abstract: Focusing on the computing processing ability of critical application and localization, and based on the character analysis of Loongson 3A processor, a Loongson 3A high performance processing module based on NUMA parallel computing architecture is proposed. Furthermore, key points required for anti-harsh is analyzed and designed, and heat dissipation, power supervisor, power supply and boot up speed technology are solved. The performance can feed the demand of critical application through test. Consequently, the performance of memory accessing is improved. The relationship between the account of CPUs and the corresponding improvement of performance under SMP and NUMA is also be discussed.
