Technical Field

The invention relates to the field of optical information calculation, in particular to a base number adjustable multi-core optical fiber abacus scheme.

Background

Modern computer systems are based on a von Neumann architecture, separating both operations, computation and storage, in time and space. In this configuration, the operation is performed in a Central Processing Unit (CPU), and the storage device is used to store any result obtained by the CPU operation. This results in a "bottleneck" in the overall operating speed, i.e., data must be continuously and continuously transferred between the memory and the CPU during and after the operation of the computer, and a lot of energy is wasted. Thus, a parallel computing architecture that somehow merges the two basic tasks of computation and storage together, i.e., a non-von neumann architecture, offers tremendous potential improvements in speed and power consumption.

In recent years, computer architectures based on non-volatile memory cells have been favored by researchers, but are currently implemented on an electronic basis; meanwhile, researchers explore feasibility of photon parallel operation, and research results such as an optical bistable device computer and a three-valued optical processor are obtained at present, but the three-valued optical processor has the problems that matching with the existing logic operation is difficult, a special optical component is lack and the like.

The invention provides a photon operation scheme based on a nonvolatile storage unit, realizes a multi-core optical fiber abacus scheme with adjustable base number by utilizing an optical regulation nonvolatile storage material and referring to an operation mode of an abacus, has higher operation speed, higher stability and stronger anti-interference capability compared with an electronic-based computing system, and provides a brand-new calculation implementation means. .

the operator acquisition and triggering module (4) comprises a multi-channel photoelectric detector (401), an acquisition board card (402), an upper computer (403) and an electric pulse generator (404); the multi-channel photoelectric detector (401) detects the emergent probe light energy, converts the light signal into an electrical signal and transmits the electrical signal to the acquisition board card (402), and transmits the data to the upper computer (403) through the acquisition board card (403) for monitoring and displaying; the number of channels of the multi-channel photoelectric detector (401) corresponds to the number of 'bits' provided by the multi-core optical fiber abacus (2); the upper computer (403) interacts with the acquisition board card (402), programs the functions of the acquisition board card (402), and acquires data transmitted by the acquisition board card (402); the upper computer (403) carries out program control on the electric pulse generator (404) and controls the form of the emergent electric pulse of each channel; the electric pulse generator (404) provides a trigger signal for the pulse laser devices (101, 102, 103) to control the light pulse output of the multi-core optical fiber abacus (2), namely the functions of adjusting the operation base number, shifting operators and the like.

A multi-core optical fiber abacus scheme with adjustable base number is characterized in that a multi-core optical fiber abacus (2) is constructed based on phase-change materials in an evanescent field coupling mode, different fiber cores represent different 'bits', the value of each 'bit' is controlled by an optical pulse source module (1), each optical pulse source sends out optical pulses to realize shifting of operators, the state is reset after the low 'bit' value is fully shifted, the high 'bit' shifting is increased by one level, the value of each 'bit' is monitored in real time through a probe laser source module (3), shifting of the optical operators and acquisition of electric signals of the 'bit' value are realized through an operator acquisition and trigger module (4), and in addition, the photon abacus operation with different base numbers can be realized through trigger control of the optical pulse source module (1) in different forms.
