Multiplexing device for digital-to-analog conversion circuit and analog-to-digital conversion circuit in storage and calculation integrated chip

Abstract

A multiplexing device for a digital-to-analog conversion circuit and an analog-to-digital conversion circuit in a storage and calculation integrated chip, comprising a digital-to-analog conversion circuit (DAC) module, an analog vector-matrix multiplication operation circuit(AMAC) module, an analog-to-digital conversion circuit(ADC) module, a first many-to-one multiplexer (M1-MUX) module, a second M1-MUX module, a first one-to-many multiplexer (1M-MUX) module, a second 1M-MUX module, and a switching transistor module. At an AMAC input end, each DAC corresponds to a plurality of input ends and is shared with the first 1M-MUX module in a time multiplexing mode by means of the first M1-MUX module; at an AMAC output end, each ADC corresponds to a plurality of output ends, and is shared with the second 1M-MUX module in a time multiplexing mode by means of the second M1-MUX module; the number of DACs and ADCs is reduced, and the chip area is reduced.
