Abstract

The invention discloses an image processing device and method based on a reconfigurable memory computing technology, and the device employs a novel ReRAM device and a PIM technology, integrates the data processing and storage in the same device, and introduces a reconfigurable operation technology. The method comprises the steps that a memory is designed to calculate a PIM instruction set, a PIM program is compiled, a high-level comprehensive HLS tool is utilized to compile a program code, the program code is placed at a corresponding position, and two different image processing tasks are processed in two modes. The problem of a storage wall is effectively solved, so that the on-chip bus bandwidth of the device is large, the transmission speed is high, the power consumption is low, and theintegration level is high. According to the method, on the premise that the image resolution is not reduced, the parallelism degree of image processing and the flexibility of the system can be improved, and then the purpose of rapid image processing is achieved.

Description

technical field [0001] The present invention belongs to the technical field of physics, and further relates to an image processing device and method based on reconfigurable memory computing technology in the technical field of image data processing. The invention can be used for image processing to collect image information, preprocess, extract feature values, and output results. Background technique [0002] At present, image processing is widely used in various fields, such as remote sensing images, radar signals, scene recognition, target tracking, etc. However, due to the increasingly complex image processing algorithms, the computing power requirements of the platform are constantly increasing, and many application scenarios have higher requirements for real-time performance. Now the image processing acceleration platform based on CPU+GPU, CPU+FPGA or DSP architecture is a common solution at present. Transplanting existing image processing algorithms to GPU, FPGA or D...
