摘要：
An exemplary Data Matrix barcode decoding chip, comprising: a characteristic searching unit configured for searching for a characteristic pattern in the barcode image to determine pixel coordinates of the characteristic pattern; a barcode parameter acquiring unit configured for acquiring a barcode parameter according to the pixel coordinates of the characteristic pattern; a correction characteristic acquiring unit configured for searching for a characteristic position in the barcode image and acquiring a correction characteristic according to the characteristic position; a module information processing unit configured for calculating a grayscale value corresponding to a module according to the barcode parameter and the correction characteristic; a binarizing unit configured for binarizing the module; a codeword extracting unit configured for extracting a codeword according to the binarized module; and an error correction and decoding unit configured for decoding the codeword.
