Problems solved by technology

The more the number of channels, the faster the HS_CLK frequency that the protocol layer needs to use, the more difficult it is to realize in the process, which greatly limits the transmission speed of MIPI

Embodiment Construction

[0030] The present invention is further described in conjunction with the following examples.

[0031] Such as image 3 As shown, the MIPI interface for fast transmission can realize the improvement of the transmission speed of the MIPI protocol layer through the following steps.

[0032] Data writing step: write multiple data from different channels of the physical layer into different first-in-first-out queues FIFO;

[0033] Parallel read-out step: read the data written above from each first-in-first-out queue FIFO respectively;

[0034] Data packet acquisition step: transmit the data read from each first-in-first-out queue FIFO to the Protocol of the protocol layer;

[0035] MIPI identification steps: the Protocol at the protocol layer identifies the received data, and saves the received data as data packets of the channel corresponding to the first-in-first-out queue FIFO of the data source, and the data packets are arranged according to the clock to obtain the data of e...

Abstract

The invention relates to the field of display screen interface data transmission technology, in particular to a quick transmission MIPI. The MIPI is provided with a processor and a computer readable storage medium, wherein a computer program is stored in the computer readable storage medium, and the computer program is executed by the processor to realize quick transmission of MIPI protocol layerdata. During protocol layer data transmission, a parallel structure is adopted, multiple pieces of data from different lanes of a physical layer are written into different first-in-first-out (FIFO) queues, and then the written data is read from all the FIFO queues respectively, wherein data-writing clock frequency BYTE_CLK and data-reading clock frequency D_CLK have little difference, frequency multiplication processing is not needed, and therefore the design difficulty and technological requirement are greatly lowered. During data parallel reading, frequency multiplication processing of clockfrequency HS_CLK is not needed, so that implementation is easy, and increase of the transmission speed of the MIPI is benefited.

Description

technical field [0001] The invention relates to the technical field of display screen interface data transmission, in particular to a MIPI interface for fast transmission. The MIPI interface is provided with a processor and a computer-readable storage medium. The computer-readable storage medium has a computer program stored therein, and the computer program is processed The device implements the fast transmission of MIPI protocol layer data. Background technique [0002] In the market, display screens with resolutions above HD have become the mainstream. In terms of display interface, the previous RGB, DBI and other interfaces can no longer meet the requirements of high resolution and high refresh rate. Due to its simple connection structure, fast transmission speed, and strong anti-interference ability, the MIPI interface has become a standard configuration for high-resolution displays. The resolution is from VGA to WQHD, the resolution is getting higher and higher, and ...
