At the Silicon Photonics Development Forum of the 19th Pujiang Innovation Forum, Tao Yaoyu from Peking University's Xinyao Yue team unveiled a programmable spatial optoelectronic heterogeneous AI inference chip. It adopts a digital light intensity accumulation and multiply-accumulate split short optical path architecture, targeting low-error, low-loss and programmable AI inference acceleration, achieving first-token latency at the hundred-microsecond level.
