Zusammenfassung:The invention discloses a computer security starting method based on a heterogeneous multi-core chip. The method includes: using at least one trusted core on the basis of a heterogeneous multi-core platform to ensure security of an untrusted core. The trusted core is used as a monitoring core, and the untrusted core is used as a computing core; the trusted core and the untrusted core are heterogeneous, and a CPU core with independent intellectual property is a first choice of the trusted core. The trusted core and the untrusted core are isolated by hardware, and sensitive hardware resources are collected to the trusted core. The trusted core is communicated with the untrusted core through cooperation of shared memory and inter-core interruption. The trusted core is guided by adopting a self-developed system, and provides security services outwards, and the untrusted core is guided by adopting a UEFI (Unified Extensible Firmware Interface) system. A core of the method is to ensure the security of the untrusted
