The present disclosure relates to the technical field of trigonometric function calculations, and in particular to a trigonometric function calculation device and electronic equipment, which are used to solve the technical problem in the related art that the software takes a long time to perform trigonometric function calculations and occupies large CPU resources. The trigonometric function calculation device includes a bus interface, a function register connected to the bus interface, and a trigonometric function accelerator connected to the function register: the bus interface is configured to connect electronic equipment; the function register is configured to store The calculation data required for calculating the trigonometric function sent by the electronic device through the bus interface and the result data calculated by the trigonometric function accelerator using the calculation data; the trigonometric function accelerator is configured to After the calculation data is stored in the register, a preset trigonometric function calculation algorithm is triggered to perform calculation according to the calculation data, and the calculated result data is sent 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...
