Abstract

The invention discloses a visual processing device based on multi-layer parallel processing. The device comprises a high speed image sensor array, multiple layers of processor unit arrays and a reduced instruction-set computer (RISC) microprocessor subsystem. An image sensor is used for acquiring images of an actual world, a bottommost low-level processor unit array has a highest degree of parallelism and a relatively weak operational capability, and the degree of parallelism of the processor arrays is gradually lowered and the operational capability of the processor arrays is gradually improved with increasing of layers. A tight coupling between a hardware structure and various image processing algorithms with different degrees of parallelism and algorithm complexity is facilitated by the aid of the layered architecture. A RISC processor is used for performing system control and scheduling of image processing threads. By means of the visual processing device based on the multi-layer parallel processing, the system has high flexibility and high data throughput rate, a multi-thread concurrent working mode is achieved, image processing capacity is greatly improved, and speeds are greatly increased.

Description

technical field [0001] The invention relates to the technical field of visual processing, in particular to a visual processing device based on multi-level parallel processing, which is used to realize various image processing tasks in a flexible and high-speed manner. Background technique [0002] Image processing technology is widely used in military, industrial, and civilian fields, such as target tracking, face recognition, gait recognition, gesture recognition, robot vision, etc. How to realize high-speed real-time image processing is an important issue in the development of science and technology. Image processing has the characteristics of a large amount of data and a large amount of calculation. Even a personal computer with a strong processing capability cannot meet the real-time application requirements for some image processing tasks. Large-scale computers have powerful processing capabilities and can improve real-time performance to a certain extent, but they con...
