Problems solved by technology

However, because the MIPI Alliance has formulated different standards and protocol specifications for different camera interfaces, display interfaces, and storage interfaces, the protocol standards are more complicated, and the circuit area required for function realization is larger.
However, at present, users are pursuing thinner and lighter mobile electronic devices, which is limited by the internal space area, which poses challenges to the realization of the functions of electronic devices

example 1

[0196] Example 1. The value of the data type field is 50h, and the data packet being transmitted is a long data packet for storing scenarios.

[0197] Such as Figure 18 As shown, the data in the payload subpacket of the data packet is effectively stored data sent from the sending end to the receiving end. The data packet header subpackage is a combination with a common structure or a minimum field, and the minimum field includes at least a data type field, a data count field, an end of message (end of message, EOM) indication field, a frame number (frame number) field, and a reserved ( reserved) field.

[0198] Wherein, the message end indication field occupies 1 bit and is used to indicate the end of data stream transmission. For example, to indicate to the application layer that the data packet being transmitted is the last data packet in the transmitted data stream.

[0199] The frame number field occupies 7 bits and is used to indicate the frame number of the data pack...

example 3

[0207] Example 3: The value of the data type field is 53h, the data packet being transmitted is used for storage scenarios, and the data packet type is a negative response (negative response, NACK) short packet in the control short packet, which is used to indicate that the data packet is received abnormally.

[0208] Exemplary, such as Figure 20 As shown, the data packet header subpackage in the data packet includes a data type field, a reset request (reset request, RReq) field, a reserved (reserved) field, a CRC high eight-bit (CRC-16H) field, and a CRC low eight-bit (CRC-16H) field. -16L) field.

[0209] Wherein, the RReq field occupies 1 bit, and its usage refers to the relevant description of the CReq field in the above example 2, and details are not repeated here.

[0210] Example 4: The value of the data type field is 10h-1Fh, and the data packet being transmitted is a long data packet for displaying the scene. The value of the data type field is 30h-4Fh, and the dat...

Abstract

The invention provides a data transmission method and electronic equipment. Relates to the technical field of terminals, and can unify protocol standards, simplify a data transmission process between modules and save circuit area. The method comprises the following steps: a first transmission unit packs to-be-transmitted data of an application layer of the first transmission unit on a protocol layer of the first transmission unit to generate a data packet; the data packet comprises data type information, the data type information is used for indicating an application scene of the data packet, and the application scene comprises any one of a camera scene, a display scene and a storage scene. And the first transmission unit sends the data packet to the physical layer of the first transmission unit through the protocol layer of the first transmission unit. And the first transmission unit sends the data packet to the second transmission unit through the physical layer of the first transmission unit.

Description

[0001] This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office on November 12, 2020, with application number 202011263644.1, and the title of the invention is "A Novel Storage Data Transmission Structure", the entire contents of which are incorporated herein by reference. Applying. technical field [0002] The embodiments of the present application relate to the technical field of terminals, and in particular, to a data transmission method and electronic equipment. Background technique [0003] At present, multiple modules such as processors, display screens, cameras, and memories are integrated in electronic devices (such as mobile phones, tablet computers, etc.), so as to meet their applications in multiple scenarios such as mobile communications, entertainment, and travel. [0004] However, since there are multiple interactive interfaces between the processor and the display, camera, memory and other modules, ...
