Abstract: The present disclosure provides a method of voice chip implementation, a voice chip, an intelligent voice product, an electronic device, and a storage medium, and relates to the field of artificial intelligence (AI) such as intelligent voice and AI chips. The method may include: constructing a voice chip including a first Digital Signal Processor (DSP) and a second DSP, the first DSP and the second DSP corresponding to a same Digital Signal Processor core Identifier (DSP core IP) and adopting heterogeneous designs; and completing a chip processing function in a corresponding intelligent voice product by using the voice chip, wherein different functions are completed by using the first DSP and the second DSP respectively. By use of the solutions of the present disclosure, implementation costs can be reduced.

Abstract: A neural network processing method, a neural network processing unit (NPU) and a processing device are provided. The method includes: obtaining by a quantizing unit in the NPU float type input data, quantizing the float type input data to obtain quantized input data, and providing the quantized input data to an operation unit; performing by the operation unit of the NPU a matrix-vector operation and/or a convolution operation to the quantized input data to obtain an operation result of the quantized input data; and performing by the quantizing unit inverse quantization to the operation result output by the operation unit to obtain an inverse quantization result.
