Coprocessor calling method and system for image target detection

Abstract

The invention discloses a coprocessor calling method and system for image target detection, belonging to the field of image target detection. The method includes: a user end uses a main command packet in a preset format to call different functional IP modules in the coprocessor Perform image preprocessing; the main command package includes: the main command number, used to number the main command package; the current IP number, used to specify the function IP module called by the main command package; the preorder IP number, used to After the work of the functional IP module corresponding to the IP number is completed, call the functional IP module corresponding to the current IP number; the data source and data destination indicate the source of the image data required by the functional IP module called by the current IP number and the receiving object of the processing result; parameters Data, used to configure the parameters of the function IP module invoked by the current IP number. The command packet format proposed by the invention has the advantages of being simple and effective for the user end and the coprocessor, and convenient for multiple functional IP modules in the coprocessor to work in parallel.

Description

technical field [0001] The invention belongs to the field of image target detection, and more particularly relates to a coprocessor calling method and system for image target detection. Background technique [0002] In the field of image target detection, with the improvement of image resolution, the amount of calculation increases. At the same time, various fields have higher requirements for the real-time performance of image target detection. Object detection technology is difficult to achieve by software methods. At present, hardware acceleration methods are often used to improve computing speed, and accurate image object detection can be completed while meeting real-time requirements. [0003] In the current image object detection hardware acceleration system, it is a common method to accelerate image processing by using the characteristics of hardware circuits that can perform parallel operations. Generally, the user end (DSP / CPU) inputs the image data into the hardwa...

Problems solved by technology

[0004] However, there are following problems in this coprocessor that is integrated with multiple functional IP modules and each functional IP module can be called flexibly: when the work is called by the client, a standardized and effective calling method has not yet been formed; the client is calling multiple When functional IP modules work in parallel to improve the efficiency of hardware acceleration, it is necessary to consider the correlation between each functional IP module, that is, the called functional IP module needs to wait for the calculation results of other working functional IP modules; Problems with data transfer when grouping data sources
