Embodiment Construction

[0027] The scheme of the present disclosure overcomes the obstacle of limited processor bit width and simplifies calculation by making the multi-bit bit width (such as 24 bits) value be expressed by at least two low bits (such as 16 bits and 8 bits) bit width components complexity, thereby improving the computational efficiency of, for example, neural network computations. In one or more embodiments, the source or initial value may be divided into a high-bit part and a low-bit part according to the bit distribution and configuration information of the input multi-bit bit-width value, and for the high-bit part and low-bit Partially performing a split calculation to obtain the first component and the second component corresponding to the high-bit part and the low-bit part. Therefore, in actual calculation, at least one of the first component and the second component can be used to replace the source data to participate in the calculation. In another embodiment, the solution of ...

Abstract

The disclosure discloses a computing device and method for processing multi-bit bit width values, an integrated circuit board, and a computer readable storage medium. The computing device can be included in a combined processing device, and the combined processing device can also include a universal interconnect interface and other processing devices; the computing device interacts with other processing devices to jointly complete computing operations specified by a user; the combined processing device can further comprise a storage device, and the storage device is connected with the equipment and the other processing devices and is used for storing data of the equipment and data of other processing devices. According to the scheme disclosed by the invention, the multi-bit bit width values can be split, so that the processing capacity of a processor is not influenced by the bit width.

Description

technical field [0001] This disclosure relates generally to data processing. More specifically, the present disclosure relates to a computing device, method, integrated circuit board, and computer-readable storage medium for processing multi-bit-width values. Background technique [0002] Currently, different types of processors may process different data bit widths. For a processor that performs operations on specific data types, the data bit width it can process is often limited. For example, for a fixed-point arithmetic unit, the data bit width that it can usually handle does not exceed 16 bits, such as 16-bit integer data. However, in order to save computing cost and overhead and improve computing efficiency, how to enable a processor with a limited bit width to process more bit-width data has become a technical problem that needs to be solved. Contents of the invention [0003] In order to at least solve the technical problems mentioned above, the present disclosur...
