20220140833 | Detecting Power Supply Noise Events and Initiating Corrective Action - Techniques are disclosed relating to detecting supply voltage events and performing corrective actions. In some embodiments, an apparatus includes sensor circuitry and control circuitry. In some embodiments, the sensor circuitry is configured to monitor supply voltage from a power supply and detect a load release event that includes an increase in the supply voltage that meets one or more pre-determined threshold parameters. In some embodiments, the control circuitry is configured to increase clock cycle time for operations performed by circuitry powered by the supply voltage during a time interval, wherein the time interval corresponds to ringing of the supply voltage that reduces the supply voltage and results from the load release event. In some embodiments, the disclosed techniques may reduce transients in supply voltage (which may avoid equipment damage and computing errors) and may allow for reduced voltage margins (which may reduce overall power consumption). | 2022-05-05 |
20220140834 | MULTIPLEXING DEVICE FOR DIGITAL-TO-ANALOG CONVERSION CIRCUIT AND ANALOG-TO-DIGITAL CONVERSION CIRCUIT IN STORAGE AND CALCULATION INTEGRATED CHIP - 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. | 2022-05-05 |
