A method and system for clearing a superconducting circuit

Abstract

The present invention proposes a method and system for clearing a superconducting circuit, including: sending a clearing instruction signal to the instruction input interface of the non-destructive readout register, and the nondestructive readout register outputs data to the first magnetic flux according to the high-frequency local clock signal The sub-separation device, the first magnetic flux quantum separation device separates the output data into a reset signal and a trigger signal, and inputs the reset signal to the superconducting register between the pipeline stages of the superconducting processor; inputs the low-frequency system clock signal to the second Two magnetic flux quantum separation devices, the second magnetic flux quantum separation device splits the low-frequency system clock signal into a first low-frequency system clock pulse and a second low-frequency system clock pulse; the first D flip-flop is based on the trigger signal and the first low-frequency system clock pulse, Outputting signal pulses, the second magnetic flux quantum separation device outputs delayed pulses according to the signal pulses and the second low-frequency system clock pulse, and the non-destructive readout register is reset according to the delayed pulses to stop outputting the clearing signal.

Problems solved by technology

The design of existing superconducting circuit components is mostly based on traveling wave and flowing water, without the traditional flip-flop concept, which makes it difficult to realize the register function

In the world, research and development institutions such as the United States and Japan have proposed to use limited units to build serial shift registers, but this type of register can only be read and written by serial shifting, and its performance is relatively low.

However, no specific design has been proposed for the zero-resetting signal generator used in the multi-stage pipeline superconducting processor.

[0003] The shortcomings and deficiencies of existing superconducting circuit technology are that most processor circuit designs are based on traveling wave flow, without traditional flow mechanism

This results in low operating efficiency, cannot fully utilize the high-speed advantages of superconducting circuits, and is also difficult to be compatible with current computer software systems

Research on the invention of the superconducting register clearing signal generator is currently blank
