Embodiment Construction

[0028] Please refer to figure 1 , figure 1 A structure diagram of an image processing system according to an embodiment of the present invention is shown. The image processing system 1 includes a feature extraction module 12 and a classification module 14 . The image processing system 1 can be applied to technologies such as object recognition or neural network, for example. The image processing system 1 can be used to process an image IMG.

[0029] The feature extraction module 12 may include a plurality of feature matching units 122 . Each feature matching unit 122 may, for example, process the image IMG with a filter, wherein the filter may be, for example, a geometric pattern such as a square, a circle, or a triangle. In one embodiment, as Figure 2A , 2B As shown, the feature matching unit 122 uses a filter F1 with a size of 2×2 to process the image IMG. The filter F1 includes a plurality of parameters a1, a2, a3, a4. The image IMG is an image with a size of 4×4, ...

Abstract

The invention discloses a memory device comprising a plurality of bit lines, a plurality of word lines and a control circuit. The bit lines are used for receiving a plurality of pixel data of an image. Each word line includes a plurality of parameter cells. The parameter units of each word line are configured according to a plurality of parameters of a filter. The configurations of the word lines are different from each other. When processing a first area of ​​the image with the filter, the control circuit inputs pixel data located in the first area of ​​the image into the bit lines, and enables one of the word lines to perform operations. When processing a second area of ​​the image with the filter, the control circuit keeps the pixel data in the second area that overlaps with the first area input to the bit line, and inputs the pixel data in the second area that does not overlap with the first area Input bit lines and enable the other of the word lines for operation.

Description

technical field [0001] The present invention relates to a memory device and its operating method. Background technique [0002] Object recognition is widely used in various fields, such as self-driving, satellite image analysis, face recognition, etc. In general, a large amount of energy is consumed in the process of object recognition. In the future where energy is increasingly precious, how to reduce energy consumption is one of the goals of the industry. Contents of the invention [0003] An object of the present invention is to provide a memory device capable of reducing energy consumption of image processing and an operating method thereof. [0004] An embodiment of the present invention discloses a memory device, which includes a plurality of bit lines, a plurality of word lines and a control circuit. The bit lines are used for receiving a plurality of pixel data of an image. Each word line includes a plurality of parameter units, and each word line is coupled to...
