[0002] It is known from the prior art that a single receiving card has a load limit, and the reason for the load limit is mainly from the bandwidth limit of the random dynamic memory (such as SDRAM / DDR2 / DDR3 / DDR4, etc.) of the receiving card, especially the Caused by the inefficiency of reading a single data in a random-like dynamic memory
For the existing invention situation, if the receiving card is to be used to realize the large load function, it is necessary to start with improving the bandwidth utilization efficiency of the random dynamic memory. At present, more than 2 pixels are stored in a random dynamic memory (video data), if it is not properly reprocessed, it will lead to a sharp decrease in the bandwidth utilization efficiency of random dynamic memory

Embodiment Construction
[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0043] The present invention aims at the problem of low data reading efficiency of random dynamic memory (such as SDRAM / DDR2 / DDR3 / DDR4, etc.) figure 1 shown, including the following steps:
[0044] Step S101: Receive the merged wiring table, horizontal pre-arrangement table, vertical pre-arrangement table and video data of the host computer.
[0045] The video data in this embodiment is used to display on the LED display screen, and how many frames of pictures should be refresh...

The invention relates to the technical field of LED display, and specifically discloses a method for realizing a large loading of a receiving card, a receiving card and a data processing system, and a method for realizing a large loading of a receiving card, including collecting a combined wiring table of a host computer, a horizontal pre-set Arrangement table, vertical pre-arrangement table and video data; write video data in the random dynamic memory through the horizontal pre-arrangement table; map the line numbers of the video data stored in the random dynamic memory through the vertical pre-arrangement table, and obtain the video data New line number; rewrite the video data into the random dynamic memory through the new line number. The present invention provides an optimized dimension by merging the wiring table, the horizontal pre-arrangement table and the vertical pre-arrangement table, and ensures that the light points and the combined routing table form a corresponding relationship, and can continuously read the data of multiple pixel points in a large burst. Video data, replacing the existing method of reading one pixel at a time, significantly improves the bandwidth utilization of RAM.
Description
technical field [0001] The invention relates to the technical field of LED display, in particular to a method for realizing a large loading of a receiving card, a receiving card and a data processing system. Background technique [0002] It is known from the prior art that a single receiving card has a load limit, and the reason for the load limit is mainly from the bandwidth limit of the random dynamic memory (such as SDRAM / DDR2 / DDR3 / DDR4, etc.) of the receiving card, especially the It is caused by the inefficiency of reading a single data from the random random memory. For the existing invention situation, if the receiving card is to be used to realize the large load function, it is necessary to start with improving the bandwidth utilization efficiency of the random dynamic memory. At present, more than 2 pixels are stored in a random dynamic memory (video data), if it is not properly reprocessed, it will lead to a sharp decrease in the bandwidth utilization efficiency of...
