Abstract

The invention relates to a data processing device and a related product. The system comprises a master processing unit and at least one slave processing unit group, and each slave processing unit group comprises a shared slave processing unit and at least one parallel slave processing unit; and the master processing unit is used for sending shared data to the shared slave processing units and sending parallel computing data to the parallel slave processing units. The shared slave processing unit transmits the shared data to each parallel slave processing unit, and the parallel slave processingunits respectively receive parallel computing data in two clock periods and transmit the parallel computing data to other parallel slave processing units step by step. According to the data processing device and the related product provided in the invention, the machine learning data is split into the shared data and the parallel computing data, data interaction between the master processing unitand the slave processing unit is realized through two clock periods, the data bandwidth occupied by data interaction between the master processing unit and the slave processing unit is reduced, and the hardware overhead of a machine learning chip for transmission is further reduced.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to a data processing device and related products. Background technique [0002] With the continuous development of machine learning, more and more multi-architecture machine learning chips are gradually coming out. When these machine learning chips access or process data in the memory, due to the large amount of data required by machine learning chips and the machine The learning chip has high requirements on the speed of data processing. [0003] Common machine learning chips usually include a master computing unit and a slave computing unit. The master processing unit transmits machine learning data and computing instructions to multiple slave processing units at the same time, and multiple slave processing units transmit machine learning data and Computing instructions to perform machine learning operations. [0004] Using the above method, data transmi...
