Abstract

The invention relates to a data processing device and method and a related product. A transmission circuit in the device acquires input data required by a machine learning device from a shared memoryaccording to a data operation signal sent by the machine learning device, returns the input data to the machine learning device, and transmits the output data to the shared memory for storage after the machine learning device operates the data to obtain the output data. Since the data operation signal carries the type flag bit of the data operation signal and the information of the data to be operated, the transmission circuit can determine the type of the data operation signal according to the type flag bit in the data operation signal, and then execute the operation in combination with the data information to be operated in the data operation signal. Thus, classification is carried out according to the type flag bit of the data operation signal to quickly locate the corresponding operation, the data access logic is simplified, the data access efficiency is improved, and the access speed of the machine learning chip during data access is greatly improved.

Description

technical field [0001] The present application relates to the technical field of information processing, in particular to a data processing device, method and related products. Background technique [0002] With the continuous development of information technology and increasing demand, people have higher and higher requirements for data access and data processing, and the requirements for some processors that process data and access data are also becoming more and more stringent. Taking a general-purpose processor as an example, a multi-core processor composed of multiple general-purpose processor cores (for example, CPU cores) has become a mainstream due to its powerful parallel computing capability. [0003] However, with the continuous development of artificial neural networks, machine learning chips with more and more architectures are gradually coming out. These machine learning chips need to access data according to instructions or process data in shared storage durin...
