Array data scheduling balance voltage adjusting circuit and method based on delay chain

Abstract

The invention discloses an array data scheduling balance voltage adjusting circuit and method based on a delay chain, and belongs to the technical field of neural networks. According to the invention, by analyzing and evaluating the calculation scale of the calculation array and the data read-write scale of the memory, the working voltage of the calculation array and the memory is dynamically provided, and the storage bit number of the shift register is controlled through the delay chain by the voltage regulation module composed of the delay chain, and the shift register is used for controlling the conduction proportion of the PMOS and the NMOS to output constant voltage. The constant voltage is used for calculating the array and the memory, and the power consumption of the circuit is reduced on the premise of meeting the working performance of the circuit.

Description

technical field [0001] The invention relates to an array data scheduling balance voltage regulation circuit and method based on a delay chain, belonging to the field of artificial intelligence. Background technique [0002] In recent years, with the continuous rise of artificial intelligence, there are a large number of multiplication and addition calculations and a large number of memory data read and write operations in artificial intelligence chips. These addition and multiplication operations need to read and store a large amount of data, which will consume a large amount of power consumption. If the working voltage of the memory and the computing array are the same, it will definitely affect the working performance of the circuit and generate unnecessary power consumption. Therefore, to reduce power consumption, an appropriate voltage must be provided. [0003] The present application proposes a delay chain-based array data scheduling balance voltage regulation circuit...
