Abstract

The embodiment of the invention provides a data processing method and device. The method includes: acquiring a first set of to-be-multiplied data, bit width of each piece of data therein, a second setof to-be-multiplied data and bit width of each piece of data therein; merging all the data in the first set of to-be-multiplied data through a preset data merging manner, then determining that obtained data are a first multiplier, merging all the data in the second set of to-be-multiplied data, and then determining that obtained data are a second multiplier; carrying out a multiplication operation on the first multiplier and the second multiplier through a preset fixed-point multiplication device to obtain multiplication result data; and extracting a result of multiplication of each piece ofdata in the first set of to-be-multiplied data and each piece of data in the second set of to-be-multiplied data from the multiplication result data according to the preset data merging manner, the bit width of each piece of data in the first set of to-be-multiplied data and the bit width of each piece of data in the second set of to-be-multiplied data. Through the scheme, work efficiency of a chip using the fixed-point multiplication device can be improved, and costs can be reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] In recent years, with the continuous development of multimedia technology, modern machine vision technology and related fields, the scale of digital signal processing has become larger and larger, and the computational complexity of computers has also greatly increased. Microprocessors such as DSP (Digital Signal Processor, digital signal processing device) has higher and higher requirements for the function and computing performance of the chip that completes the operation. Among them, the multiplier is one of the core components in the chip, and the operational efficiency of the multiplier has become an important feature to measure the computing performance of the chip, which has an important impact on the performance and power consumption of the chip. [0003] In modern machine vision technology, such as the...
