DATA PROCESSING APPARATUS AND METHOD

WIPO Patent Application WO/2018/210339

A1

The present invention relates to the field of data processing and discloses a data processing apparatus and method applied to data processing and for solving the problem of, in a data processing apparatus capable of supporting both of a linear domain data processing mode and a logarithmic domain data processing mode, how to multiplex hardware resources of a logarithmic domain data processing unit when linear domain data processing is performed, so as to enhance utilization of hardware resources. In a specific solution, when performing a multiply-accumulate calculation on input data, a linear domain-to-logarithmic domain unit (22) is first enabled according to a first enable signal to convert the input data into logarithmic domain data, and then a multiply-accumulate calculation is performed on the logarithmic domain data by a logarithmic domain multiply-accumulate unit array (25); and when performing a multiplication calculation on input data, a linear domain data extending and encoding unit (23) is first enabled according to a second enable signal to perform pre-processing of input data, and then a multiplication calculation is performed on the pre-processed data by the logarithmic domain multiply-accumulate unit array (25).
