Problems solved by technology

The common hardware acceleration structure is based on SIMD (Single Instruction Multiple Data), so the acceleration effect on this iterative network is very limited. It takes tens to hundreds of seconds to generate a voice with a length of 1 second, which is completely unsatisfactory. The actual needs of real-time speech generation products

Abstract

The invention discloses an acceleration device for deep learning and a computing device for deep learning. The acceleration device for deep learning comprises a data buffer and an operation module connected with the data buffer; the data buffer is used for caching an intermediate calculation result of a network layer of the vocoder neural network; and the operation module is used for obtaining anintermediate calculation result of a first network layer of the vocoder neural network from the data buffer according to the received control instruction, and sending the intermediate calculation result of the first network layer to the data buffer. By adopting the acceleration device for deep learning provided by the invention, the processing efficiency of the vocoder neural network is improved.

Description

technical field [0001] This application relates to the field of circuit design, in particular to an acceleration device and a computing device for deep learning. Background technique [0002] In the field of artificial intelligence applications, voice applications account for a considerable proportion. Text-to-speech (TTS, Text to speech) technology, as a voice application, is often used in human-computer interaction. Generally, the TTS algorithm can be further divided into three parts: the front-end for preprocessing text into linguistic features such as morphemes, the back-end for transforming linguistic features into acoustic features such as spectrum and phoneme, and the use of acoustic features The vocoder that generates the final speech. In these three parts, since the output frequency of the vocoder is equal to the sampling frequency of the audio signal, that is, 16-22kHz, the vocoder has a large amount of calculation and memory access, which has always been the bot...
