Problems solved by technology

What affects data transmission performance in the system is often the data transmission method. Data of different types, different formats, and different priorities are transmitted in the same channel, causing channel preemption and reducing data transmission efficiency.
The uncertain delay of high-speed data is often the main reason for reducing the performance of data transmission, thus affecting the actual response rate of the high dynamic response requirement tracking system
Between different types of modules, the data bus is not universal, the transmission format is uncertain, and the interconnection is difficult, which further aggravates the effectiveness and timeliness of data transmission

Abstract

The invention discloses a dual-bus high-speed image processing system and method. By using two sets of high and low data transmission bus systems, the high-speed bus adopts a pre-set priority preemption mechanism for point-to-point high-speed image transmission, and supports parallel multi-channel binding mode. The transmission mode increases the bandwidth, and multiple high-speed channels are transmitted in parallel in the demultiplexing mode; the low-speed bus adopts the level-level contention and round-robin mechanism for general command transmission to achieve the purpose of better data transmission performance in the system; The image data transmission channel is separated from the low-speed command transmission channel to achieve the purpose of not affecting the overall delay of the system, and the data and command interfaces are generalized and easy to develop. It can be used for rapid processing and identification of high-dynamic target imaging, such as high-dynamic target strike equipment The closed-loop tracking and aiming loop image processing system, etc.; the invention improves the high-speed bus transmission efficiency, has the advantages of flexible high-speed data transmission mode, convenient development and expansion, and the like.

Description

technical field [0001] The invention relates to the field of image processing, and more particularly, to a dual-bus high-speed image processing system and method. Background technique [0002] The image processing system is an important part of the high dynamic target strike equipment. Its purpose is to process and identify the target image signal, and feed back the identification results to the control and strike system, and finally complete the pointing control, target recognition and tracking, aiming and striking, etc. Complete closed-loop strike function. [0003] In order to achieve real-time tracking, aiming and attacking of high-dynamic targets, the image processing system is required to have high image processing capabilities and a high level of internal data transmission capabilities. The internal data transmission capability determines the speed and efficiency of data transmission between internal modules, and indirectly determines the high dynamic response rate o...
