Abstract

The invention relates to the technical field of trigonometric function calculation, in particular to a trigonometric function calculation device and electronic equipment, and aims to solve the technical problem that software needs to consume for a long time to perform trigonometric function operation and occupies large CPU resources in related technologies. The trigonometric function calculation device comprises a bus interface, a function register connected to the bus interface and a trigonometric function accelerator connected to the function register, wherein the bus interface is configured to be connected with electronic equipment; the function register is configured to store calculation data which is sent by the electronic equipment through the bus interface and is used for calculating a trigonometric function and result data calculated by the trigonometric function accelerator by utilizing the calculation data; and the trigonometric function accelerator is configured to trigger the use of a preset trigonometric function calculation algorithm for calculation according to the calculation data after the function register stores the calculation data, and send the calculated result data to the function register.

Description

technical field [0001] The present disclosure relates to the technical field of trigonometric function calculations, in particular to a trigonometric function calculation device and electronic equipment. Background technique [0002] In the field of microcontrollers, generally speaking, trigonometric function operations can be calculated by software, and different algorithms can be used to achieve different functions (sin / cos / arctan), different performance (10μs / 5μs), and different precision (8 / 16bit effective digits), the advantage of this is that it can be flexibly configured, and customized software design can be done according to your own project requirements. For example, STMicroelectronics has launched a set of math libraries. According to its own chips, sin and The trigonometric function algorithm of cos, but not optimized for arctan. Contents of the invention [0003] The present disclosure provides a trigonometric function calculation device and electronic equip...
