Abstract: This application provides a secure boot apparatus and method. A control circuit in the secure boot apparatus can obtain boot code in a nonvolatile memory by using a non-programmable circuit, and verify the boot code by using a root of trust. In this way, even if the root of trust is not built in a processor, the verification on the boot code can be implemented by using the control circuit. This effectively reduces dependency of a secure boot process on processor performance. In addition, because the non-programmable circuit can be respectively coupled to the control circuit and the nonvolatile memory through two interfaces of different types, a requirement for the secure boot process on an interface protocol type of the control circuit is reduced, and application flexibility of a secure boot solution is improved.

Abstract: A signal processing method and apparatus. According to the signal processing method, phase change processing can be performed on to-be-sent data signals according to a phase status of a data synchronization signal and phase statuses of the to-be-sent data signals, so that phase differences between a majority of to-be-sent data signals in the processed to-be-sent data signals and the data synchronization signal meet a certain condition, thereby reducing a volume of coupling crosstalk, generated by the to-be-sent data signals, on the data synchronization signal and further reducing impact of simultaneously switching noise (SSN) on a system.
