Abstract

The invention provides a data processing method and device. The method comprises the following steps: acquiring to-be-processed data and an operation code thereof; wherein the operation code is used for indicating the type of a function for calculating the to-be-processed data; preprocessing the to-be-processed data; the preprocessed data to be processed comprises a first data segment, a second data segment and a third data segment, the first data segment is used for generating a table look-up address, the second data segment is used for participating in function calculation, and the third data segment is used for indicating a decimal point position of the second data segment; generating a table look-up address according to the first data segment and the operation code, and looking up a quadratic polynomial coefficient in a coefficient table through the table look-up address; and performing interpolation calculation according to the quadratic polynomial coefficient and the second data segment, performing post-processing on an interpolation calculation result, and obtaining a calculation result of the to-be-processed data according to the decimal point position indicated by the third data segment. According to the method, high-precision and high-speed calculation of a plurality of different functions is realized, and the overhead of calculation and storage resources is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method and device. Background technique [0002] Embedded computing is ubiquitous and requires a large number of real-time elementary function calculations, especially the calculation of transcendental functions such as reciprocals and square roots. Although these elementary functions can be accurately approximated by software, the timeliness is poor for vector calculation or real-time systems. Hardware implementation has more advantages than software implementation in function computing. It can further increase throughput through hardware-level parallelism, and has a greater advantage in latency. In the communications industry, ever-increasing throughput demands and latency demands further drive the development of high-speed, low-latency, high-throughput computing. Correct and efficient calculation of these elementary functions is very importa...
