Abstract
A digital signal modulation method for a photon artificial intelligence computing chip, including: modulating one or more groups of digital electrical signals into optical signals; where the group of digital electrical signals comprises several timing signals being outputted in sequence in a channel within a fixed period; where each timing signal has the same base clock and signal time length; where each timing signal conveying N-bit digital information has 2N−1 base clocks, the number of the base clocks of a high-level signal or the number of a digital signal “1” in the timing signal is a signal value of the timing signal, and the signal value is equal to a value of the N-bit digital information being transmitted; and where the timing signal is a modulating signal for converting the electrical signal to the optical signal. Compared with the existing calculation scheme based on digital-to-analog conversion and analog signal modulation, the calculation scheme in the present invention avoids using a digital-to-analog converter with a high cost and power consumption, can be directly connected with the digital signals of the electronic chip, and avoids quantization error during the dig…
