The embodiment of the invention provides a safety computer platform compatible with double 2-vote-2 and 3-vote-2 and vehicle-mounted equipment, the safety computer platform comprises a first board card and a second board card, three computing units are arranged in the first board card, and at least two computing units are arranged in the second board card. When the security computer is switched toa double 2-vote-2 architecture, the two computing units in the first board card and the two computing units in the second board card are used for processing input data; and when the secure computer is switched to the 3-vote-2 architecture, the three computing units in the first board card process the input data. The double 2-vote-2 architecture and the 3-vote-2 architecture can be switched to each other, and seamless compatible use is realized.

    本发明实施例提供了一种兼容二乘二取二和三取二的安全计算机平台和车载设备,安全计算机平台包括第一板卡和第二板卡,所述第一板卡中设置有三个计算单元,所述第二板卡中设置有至少两个计算单元。当安全计算机切换到二乘二取二架构时,由所述第一板卡中的两个计算单元和所述第二板卡中的两个计算单元对输入数据进行处理;当所述安全计算机切换到三取二架构时,由所述第一板卡中的三个计算单元对输入数据进行处理。二乘二取二架构和三取二架构能够互相切换,实现无缝兼容使用。
