Abstract

Disclosed are an operational circuit, a chip and a board card. The operational circuit may be implemented as a computing device included in a combined processing device, which may also include an interface device and other processing devices. The computing device interacts with other processing devices to jointly complete computing operation specified by a user. The combined processing device can further comprise a storage device, and the storage device is connected with the computing device and the other processing devices and used for storing data of the computing device and the other processing devices. According to the scheme disclosed by the invention, the operational circuit is optimized, multiple modes of multiply-add operation are realized, and the flexibility of an operational device is improved.

Description

technical field [0001] The present disclosure relates generally to the field of circuits. More specifically, the present disclosure relates to an arithmetic circuit, a chip and a board. Background technique [0002] At present, deep learning (Deep Learning) has become an important branch of machine learning, and it is also vigorously promoting the development of artificial intelligence (AI). The core technology of deep learning - deep neural network (DNN) has been widely used in many industries. [0003] There are a large number of multiplication, addition, and mixed operations of multiplication and addition in the neural network model, and these operations can be realized by corresponding operation circuits. However, the input data source of each computing device (such as a multiplier) in the current computing circuit is often fixed, which makes an computing circuit only execute a predetermined computing mode, resulting in poor flexibility of the computing device . Con...
