Title:
DEVICE AND METHOD FOR COMPARING DATA
Document Type and Number:
WIPO Patent Application WO/2017/101083
Kind Code:
A1
Abstract:
A device and a method for comparing data. The device comprises a conversion module and a comparison module, the comparison module consisting of at least one comparison unit. Elements in reference data correspond to elements in first data one by one. The conversion module respectively generates, for each element included in first data, an optical signal of different wavelength, and distributes the optical signal to each comparison unit (801); different comparison units correspond to different reference data, each comparison unit compares the corresponding reference data thereof to the first data; a first comparison unit controls an optical signal, which has a wavelength corresponding to the element that is different in the first data and in first reference data, to be output from a first comparison output port, and control an optical signal, which has a wavelength corresponding to the element that is identical in the first data and in the first reference data, to be output from a second comparison output port (802). Said device achieves the comparison between the first data and one or more reference data.
