It can be appreciated that the at least two operating systems may be in one-to-one correspondence with at least two hardware domains of the multi-core heterogeneous SOC; there may also be cases where at least two of them run in the same hardware domain. This is not particularly limited in this application.
And, the at least two operating systems include a first operating system, and the first operating system may have authority to control start-up for a certain hardware domain (including a hardware domain where the first operating system itself is located) or all hardware domains in the multi-core heterogeneous SOC.
