Embodiment Construction

[0031] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0032] With the rapid development of information technology, the era of big data has come. The large amount of data collected by IoT sensing technology requires low-power and high-energy-efficiency processing. Traditional computing platforms, such as CPUs and GPUs, are approaching the limit of Moore's Law, and the improvement of computing power is coming to an end. Memristor is a new type of micro-nano electronic device, whose resistance state can be adjusted by external voltage excitation. Memristor-based neuromorphic com...

Abstract

The invention relates to the technical field of integrated circuits, in particular to a multi-bit input data coding method and device, electronic equipment and a storage medium, the method is applied to a memristor storage and calculation integrated system, and the method comprises the following steps: in the memristor storage and calculation integrated system, obtaining at least one piece of multi-bit data; generating a plurality of weighted pulse groups for representing the multi-bit data from the at least one multi-bit data; and calculating a calculation result of the pulses of each weighted pulse group, and performing weighted summation according to the calculation result of the pulses of each weighted pulse group and the corresponding weight to obtain a multi-bit input data coding result. Therefore, the problems that the operation precision, the operation time and the hardware overhead are difficult to compromise and the like in the multi-bit input data coding type of the memristor storage and calculation integrated system in the related technology are solved.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, and in particular to a multi-bit input data encoding method, device, electronic equipment and storage medium. Background technique [0002] In related technologies, the encoding types of multi-bit input data of the memristor storage and calculation system mainly include pulse duration (width) encoding, pulse amplitude value encoding and pulse number encoding, and the pulse number encoding mainly includes general pulse There are two types of number coding and bit-by-bit weighted pulse number coding, that is, there are four types in total. [0003] However, there are four types of multi-bit input data encoding in the related art: pulse width encoding, pulse amplitude value encoding, general pulse number encoding, and bit-by-bit weighted pulse number encoding. problem, to be solved. Contents of the invention [0004] The present application provides a multi-bit input data e...
