Problems solved by technology

Even if the speed of each system is very fast, due to the limitation of transmission bandwidth, the whole system can only run at a low speed; 3. Image processing limitations
The general algorithm, once written into the ISP, cannot be changed, so the ability of the algorithm to process images is limited to the image processing features that the algorithm can support, and there will be certain limitations on the flexibility of image processing

Abstract

The invention discloses an image processing system architecture. The image processing system architecture comprises a pixel array, a synaptic array and a neuron circuit array. The synaptic array comprises multiple stages of synaptic arrays. The neuron circuit array comprises multiple stages of neuron circuit arrays, and any two neurons in each two stages of neuron circuit arrays are respectively connected by one synaptic in one synaptic array. According to the architecture, image processing does not need extra conversion between analog and digital signals, real-time parallel processing can berealized, and the processing speed is improved.

Description

technical field [0001] The invention relates to the field of CMOS integrated circuit design, in particular to an image processing system architecture based on a neural network. Background technique [0002] With the development of CMOS integrated circuit technology, electronic imaging products are more and more widely used in daily life and industrial production. Correspondingly, image processing technology can be used as an automatic image processing technology and plays an important role in key fields such as intelligent monitoring, aerospace, intelligent driving, rapid identification, and accurate capture. The development of artificial intelligence algorithms has also accelerated the breadth of image processing. In today's applications, image processing systems are often composed of two parts, such as figure 1 shown. The former part is an image sensor, which mainly includes a photosensitive pixel array and a corresponding analog-to-digital conversion circuit, which con...
