A training method based on cmos image data of alternately transformed pulses

Abstract

The training method based on the CMOS image data of alternately transformed pulses relates to a training method of CMOS image data, which solves the problem of obtaining wrong training words when the existing CMOS image data is converted from serial to parallel during transmission, and the training system includes CMOS image data. The sensor and data processor are composed of two parts. The data processor includes iodelay1, iserdes1, data asynchronous FIFO, control asynchronous FIFO, gearbox, ram based shifer and controller. As the core of the CMOS data training system, the controller controls the coordination of various parts. Under the control of the controller, the CMOS image sensor outputs serial image data through iodelay1, iserdes1, data asynchronous FIFO, gearbox, ram based shifer, and finally converts it into parallel image data with bit width p. The invention proposes a training method based on alternately changing pulses to ensure the correctness of the word correction combination corresponding to the correct training word, thereby ensuring the correctness of channel training.

Description

technical field [0001] The invention relates to a training method for CMOS image data, in particular to a training method for high-resolution and high-frame-frequency CMOS image data based on alternately transformed pulses. Background technique [0002] Nowadays, CMOS image sensors with high resolution (not less than 10k×10k) and high frame rate (not less than 20fps) usually use multiple (not less than 80 channels) high-speed serial channels for image data transmission, each data transmission There is no definite phase relationship between the channels every time they are powered on, which brings great difficulties to the serial-to-parallel conversion of data. Direct use of the internally integrated iserdes1 module such as virtex 6 cannot meet the requirements of high-bit-width applications, and further serial-to-parallel conversion is required; incorrect data position combinations may occur in the word correction process to obtain correct training words, while channel train...
