摘要： A communication apparatus and an electronic device for implementing multi-carrier aggregation are provided. The communication apparatus includes a transceiver and an antenna array. The transceiver is coupled to a plurality of radio frequency channels, and the plurality of radio frequency channels are coupled to all antenna units in the antenna array in a one-to-one manner. Each of the plurality of radio frequency channels includes a phase shifter, and the phase shifter is configured to set a phase of a radio frequency signal transmitted in the radio frequency channel. The antenna array includes a plurality of first antenna units and a plurality of second antenna units. The plurality of first antenna units are configured to transmit a plurality of radio frequency signals of a first band, to form a first carrier signal pointing to a first direction.

摘要： A trusted kernel starting method and apparatus are provided. The method includes: starting a security boot module boot loader; invoking the boot loader to measure, according to a first security algorithm, whether a platform configuration register (PCR) partition is trusted; if the PCR partition is trusted, invoking the boot loader to read kernel code into a memory, and invoking the boot loader to measure, according to a first complete algorithm and a kernel code standard measurement value prestored in the PCR partition, whether the kernel code is trusted; initializing, if the kernel code is trusted, the kernel code to trigger an initialized kernel to measure, according to a second complete algorithm, whether the boot loader is trusted; and starting the kernel if the boot loader is trusted. Kernel starting security is improved.

摘要： Embodiments of the present invention disclose a method and an apparatus for controlling memory startup, and relate to the field of memory control technologies. The present invention is not limited to the number of pins of a control chip, thereby reducing costs. The method is applied to a control apparatus, where the control apparatus includes a preset data segment; the preset data segment includes at least one sub data segment; and each sub data segment is corresponding to one configuration type. The method includes: reading each sub data segment in a first data segment and performing a first operation on a sub data segment corresponding to a first configuration type to obtain a second data segment; performing matching between the second data segment and the preset data segment; and starting up the memory according to the first configuration type when the second data segment matches the preset data segment.
