Abstract

The invention provides a system for loading and extracting parallel information of an optical vector-matrix multiplier. The system serves as an independently running organic whole with a self-contained system and slips the leash of discrete equipment such as a signal generator, an oscilloscope and an optical amplifier, and the optical vector-matrix multiplier can be conveniently, visually, flexibly and accurately tested and analyzed.

Description

technical field [0001] The invention relates to the technical field of optical information processing, in particular to a system for loading and extracting parallel information of an optical vector-matrix multiplier. Background technique [0002] The optical information processing method has the advantages of large bandwidth, strong parallelism, and small crosstalk. The vector-matrix multiplier based on the optical information processing method is suitable for completing intensive vector-matrix multiplication (Vector Matrix Multiplication, VMM) tasks and realizing high-speed multiplication and accumulation. (Multiplication and Accumulation, MAC) operation. The MAC operation is the core operation process in the process of digital signal processing. The study of optical digital signal processing technology based on optical vector-matrix multiplier can break through the bottleneck of electronic computing and realize high-speed optical computing. This technology can be widely u...
