Embodiment Construction

[0044] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0045] As mentioned in the background technology, at present, when importing and exporting the debug code stream, several frames of continuous images are first continuously captured and temporarily stored in the memory, and then the capture is stopped and then slowly written from the memory to a local storage such as Flash, or through a peripheral interface such as EMAC is sent to the host computer. However, due to the impact of the available memory size, when the amount of image frame data is relatively large, the number of image frames that can be captured continuously is very small, thus limiting the import and export speed of the debug code stream.

[0046] In order to overcome the above-mentioned problems that the original image code stream is very large, w...

Abstract

The present application discloses a method for deriving a debugging code stream for image processing, including: a node selection unit enables at least one port of a debugging node corresponding to the debugging request according to the debugging request; Compression: the memory management unit writes the lossless compressed code stream into the memory used to save the code stream of the debugging node, reads the lossless compressed code stream from the memory, and saves it to the storage device or transmits it to the upper level through the input and output control unit machine. The application also discloses a debugging code stream importing method for image processing and an importing and exporting device. By applying the present application, the efficiency of importing and exporting image debugging code streams can be improved.

Description

technical field [0001] The present application relates to image processing technology, and in particular to a method and device for exporting and importing debug streams for image processing. Background technique [0002] Video capture chips (including FPGA products) are more and more widely used, and are needed in mobile phones, surveillance, artificial intelligence, home appliances, consumer electronics, and industrial control. The video acquisition part in the video acquisition chip includes multiple links such as Sensor reception, image signal processing, post-processing, encoding, and display, such as figure 1 shown. The image format of the image processed in the video capture chip includes the original capture format received by the Sensor such as BAYER format, RAW RGB and YUV formats in the conversion stage, and encoded H.264 / H.265. In order to ensure the correctness of the image algorithm and hardware functions, it is necessary to consider filling or exporting the ...
