Target detection system and method for realizing parallel two-dimensional transmission of data strings by utilizing DMA controller

The invention discloses a target detection system and method for realizing parallel two-dimensional transmission of data strings by using a DMA controller. The system comprises a detector, an upper computer, an FPGA, a recorder and a multi-core ARM processor, after the detector is powered on to work, an image obtained through real-time detection is transmitted to the multi-core ARM processor; themulti-core ARM processor selects a corresponding image preprocessing algorithm according to an instruction sent by the upper computer to preprocess the received image, and sends the preprocessed imageto the FPGA; and the deep learning IP core mounted on the FPGA performs deep learning target recognition calculation on the received preprocessed image data, and a calculation result is fed back to the recorder and the upper computer through the multi-core ARM processor. The system can support a neural network operation algorithm unit, and is a software architecture system which has the characteristics of strong real-time
