Description

Method and device for sending instruction at fixed time Technical Field The present application relates to the field of terminal devices, and in particular, to a method and apparatus for sending an instruction in a timing manner. Background When the wide-narrow band satellite communication chip works, a Front-end module (FEM) device at a later stage is controlled by issuing an instruction, so that related functions are realized. However, the wide-narrow band satellite communication chip may issue multiple instructions at the same time, such as voltage configuration, power Amplifier (PA) initialization, etc. The execution of these instructions requires a sequential order, which is sent to the FEM device for execution at different times. Therefore, after the instructions are reasonably ordered, the instructions are sent to the FEM device for execution, so that the working efficiency of the chip is improved. Disclosure of Invention The embodiment of the application provides a method and a device for sending instructions at regular time, which aim to order the instructions in the process of writing the instructions issued by a wide-narrow-band satellite communication chip into a memory, reduce ordering delay and improve the working efficiency of the chip. In a first aspect, an embodiment of the present application provides an instruction timing transmitting apparatus. The device comprises a first communication chip, a sequencing control module and a front-end FEM module, wherein the first communication chip is connected with the front-end FEM module through the sequencing control module, the first communication chip is used for issuing a plurality of to-be-sequenced control instructions, each to-be-sequenced control instruction comprises a first time stamp and instruction information, the sequencing control module is used for sequencing the plurality of to-be-sequenced control instructions based on the first time stamp of each to-be-sequenced control instruction in the process of receiving the plurality of to-be-sequenced control instructions to obtain a plurality of sequenced control instructions, each sequenced control instruction comprises the first time stamp and the instruction information, and the front-end FEM module is used for sequentially acquiring the plurality of sequenced control instructions and configuring the to-be-sequenced control instructions based on the instruction information of each sequenced control instruction. By way of example, the first communication chip may be a broadband and narrowband satellite communication chip, and the control instructions issued by the first communication chip include, but are not limited to, voltage configuration, PA initialization, and the like, and these instructions are used to configure FEM devices of a subsequent stage. The frequency and number of instructions issued by the controller are determined according to the current working state of the controller, and the embodiment of the application is not limited to the frequency and number of instructions issued by the controller. For example, the value corresponding to the first timestamp of each control instruction to be sequenced may be different or the value corresponding to the first timestamp may be the same, which is not limited in the embodiment of the present application. For example, after the control instruction to be sequenced is issued to the sequencing control instruction, the sequencing control module will buffer the control instruction first, then sequence the control instruction, and send the control instruction to the front-end FEM module temporarily at the time corresponding to the timestamp. It can be understood that the first time stamp and the instruction information of the control instruction to be sequenced are the same as those of the sequenced control instruction, and the sequencing operation of the sequencing control module is just to perform the operation of storing the address in the memory. For example, after the ordering control module finishes ordering the control instruction to be ordered, the front end FEM module sequentially acquires the ordered control instruction based on the ordering, and configures based on the instruction information of the ordered control instruction. Therefore, the control instructions issued by the wide-narrow band satellite communication chip are ordered, so that the control instructions can be executed by the front-end FEM module according to the time sequence, and the working efficiency of the chip is improved. According to the first aspect, the device further comprises a sending control module, the ordering control module is connected with the front-end FEM module through the sending control module, and the sending control module is used for sequentially reading instructions of the ordering control module and sending the ordered control instructions obtained through reading to the front-end FEM module according to the first time stamp correspon
