Problems solved by technology

[0003] However, the existing CORDIC processors can only implement a single calculation function, for example, only the function of rotation, or the function of solving the arctan angle, etc.
When the system requires multiple computing functions, multiple single-function CORDIC processors need to be deployed, which consumes more resources and increases system power consumption

Abstract

The embodiment of the invention discloses a coordinate rotation digital processor. The processor has a mode selection function. When a mode selection signal is a first value, the processor can achieve the coordinate rotation function, and an initial input signal is rotated by a first angle to obtain a rotated output signal; when the mode selection signal is a second value, the processor achieves the arctan solution function. The processor can achieve the coordinate rotation function and the arctan angle solution function respectively according to selected modes. Compared with an existing single-function processor, the CORDIC processor can effectively reduce the requirements for system resources and lower system power consumption.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a coordinate rotation digital processor. Background technique [0002] The CORDIC (Coordinate Rotation Digital Computer) method was first proposed by J.D. Volder1 in 1959 and is mainly used for the calculation of trigonometric functions, hyperbolas, exponentials, and logarithms. The algorithm replaces the multiplication operation with the basic addition and shift operation, so that the calculation of the rotation and orientation of the vector no longer needs functions such as trigonometric functions, multiplication, square root, inverse trigonometric, and exponent. [0003] However, the existing CORDIC processors can only implement a single calculation function, for example, only the function of rotation, or the function of solving the arctan angle, etc. can only be realized. When the system requires multiple computing functions, multiple single-function CORDIC processors...
