TMS320C6678 is a multi-core DSP processor with higher processing speed compared with other single-core DSPs. This paper proposes a convolutional neural system based on the technical requirements of TMS320C6678 processing target detection technology to enhance real-time and reduce false alarm rate. Infrared weak target detection algorithm for networks. Pre-processing methods such as image denoising and enhancement and Kronecker product up sampling are used to expand the target size and enhance the morphological features while reducing the difficulty of detecting weak targets. Then the design is more suitable for detecting the convolutional neural network structure of weak targets. Extracting the deep features of infrared weak targets can accurately detect weak targets in infrared images while effectively eliminating various disturbances such as features and clouds. The simulation results show that the target detection probability of the algorithm is 95%, with low time complexity, strong resistance to ground and cloud interference, and high detection accuracy. At present, the core part of the algorithm is transplanted into TMS320C6678, the processing speed is much higher than the simulation result, the real-time performance is confirmed, and it has high engineering application value.
