Multi-input parallel multiplication, addition, storage and calculation integrated circuit based on Hall strip

Abstract

The invention discloses a multi-input parallel multiplication, addition, storage and calculation integrated circuit based on a Hall bar. The multi-input parallel multiplication, addition, storage and calculation integrated circuit comprises an input coding module, a parallel multiplication module and an analog addition module. The input coding module is used for coding an input signal into a current signal. The parallel multiplication module comprises a plurality of parallel Hall strips, the current of the input end of each Hall strip is used as a multiplier of multiplication, the resistance value is used as a multiplicand, and the Hall voltage of the output end is used as a multiplication result. And the parallel Hall strips output respective multiplication calculation results, and accumulation is completed in the analog addition module, so that multiplication and addition operation of the circuit is realized. Because the multiplicand Hall resistance value is directly stored in the Hall strip, the circuit can achieve the purpose of integrating storage and calculation without an additional storage unit. The storage and calculation integrated circuit has the advantages of non-volatile storage of multiplicands, continuous change, multi-input parallel operation and the like, and is very suitable for hardware acceleration of convolutional neural network calculation.

Problems solved by technology

In the traditional Von Neumann computer system, due to the separation of the storage unit and the computing unit, the process of data transfer from the memory to the computing unit consumes nearly 1000 times the computing power consumption, resulting in the existence of a "storage wall" between the CPU and the memory. " and "power consumption wall" have become the main problems in improving computer performance, so we have to find a new architecture system to reduce the power consumption caused by data handling
