The invention provides a data flow path device suitable for a storage and calculation integrated array and a method thereof. The device comprises a global buffer area which is used for caching an intermediate result of a reasoning process and transmitting ready data of a next step to a waiting area register group; the waiting area register group is used for storing and driving input data to enter the storage and calculation integrated array for calculation; the storage and calculation integrated array is used for realizing convolution operation and full connection layer calculation in a neural network reasoning process according to pre-mapped weight information and transmitting an obtained calculation intermediate result to the single-instruction multi-data-stream module; and the single-instruction multi-data-stream module is used for realizing pooling operation in a neural network reasoning process, activating functions and transmitting a result to the global buffer area. According to the data flow path devi
