Abstract

The present disclosure discloses a data processing device, an integrated circuit chip, a board card, and a computing device for data processing, the computing device may be included in a combined processing device, which may also include a universal interconnect interface and other processing devices. And the computing device interacts with other processing devices to jointly complete the computing operation specified by the user. The combined processing device can further comprise a storage device, and the storage device is connected with the equipment and other processing devices and used for storing data of the equipment and other processing devices. According to the scheme, the data with the high bit width value can be split, so that the processing capacity of the processor is not influenced by the bit width, the operation is accelerated, and the calculation overhead is reduced.

Description

technical field [0001] The present disclosure relates generally to the field of data processing. More specifically, the present disclosure relates to a data processing device, a method for data processing, an integrated circuit chip, a board, and a computing device. Background technique [0002] Existing central processing units (“CPUs”) and graphics processing units (“GPUs”) generally use floating-point arithmetic units that support floating-point operations to train neural networks. However, the floating-point arithmetic unit has defects such as high power consumption, large area and low efficiency in operation. Therefore, in some calculation scenarios, it is desirable to use fixed-point numbers for calculations to overcome the aforementioned various defects. However, the training of neural networks has relatively high requirements for the representation accuracy of data. When the bit width of the fixed-point number is limited, it often leads to the loss of data precisi...
