Abstract

The invention discloses a serial adder, comprising: an I2C controller, an I2C command analysis circuit, a system control circuit, a low-speed data transmission circuit, a high-speed data conversion circuit, a low-speed data processing circuit, an I2S receiver, a parallel-to-serial conversion bidirectional circuit, Serial-to-parallel conversion circuit, protocol analysis circuit, video data processing circuit and I2S receiver, the serializer in the present invention can not only receive the external control command sent by the external controller through the I2C controller, but also can receive through the parallel-to-serial conversion bidirectional circuit External control command and internal control command, at the same time, the serializer can also receive the video data sent by the external video source through the serial-to-parallel conversion circuit, and receive the audio data sent by the outside through the I2S receiver, therefore, the serializer in the present invention The serializer can be applied to the two application scenarios of the serializer shown in the background art, so that the application of the serializer is more flexible.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a serializer. Background technique [0002] Usually the video data collected by the video source will be displayed on the display screen after being processed by the processor. In practical applications, when the installation distance between the video source and the processor is long, or when the installation distance between the processor and the display screen is long, in order to realize the transmission of video data, it is usually set on the transmission channel serializer and deserializer. [0003] Referring to the schematic diagram of a video data transmission path shown in Figure 1(a), the video source can be the camera used for the reversing image at the rear of the car, and the processor can be the central control system inside the car. The processor is far away, therefore, the video source and the processor cannot transmit video data t...
