把双核拆成了两个单核, 分别计算同样的数据。 每个系统配置3块芯片做冗余, 也就是6个核做计算。
据SpaceX前火箭总师John Muratore透露, 龙飞船一共有18个系统, 每个系统配置了3块X86芯片, 龙飞船一共有54块。
猎鹰九号一共有9个分立式发动机, 每个发动机配置了3块X86芯片, 加上主控系统配置了3块, 猎鹰九号一共有30块这样的芯片。
潜在的,神经网络硬件加速的特性有可能对辐射不敏感:

IRF7NA2907 封装为 SMD-2,IRF7N1405封装为 SMD-1。由于单个 SMD-2 封装的器件外加钽片增加的质量约为 1.19 g,单个 SMD-1 封装的器件外加钽片增加的质量约为 0.96g,所以二次电源增加的总质量约为 11.5g(钽的密度为 16.67g/cm3)
