More Information
Summary:The invention discloses a cubic root solving device and method based on hyperbolic CORDIC. According to the method, cubic root calculation is converted into logarithm and exponent which can be calculated through a CORDIC algorithm under a generalized hyperbolic coordinate system. The device is characterized in that a logarithm input preprocessing module converts any positive number x into 8k*r, alogarithm calculation module is used for calculating a hyperbolic arc tangent value based on 8 through a generalized hyperbolic CORDIC calculation unit working in a vector mode, and then obtaining a logarithm index through shifting and adding operations, and splitting the logarithm index preprocessing module into an integer part I and a decimal part F, and an index calculation module is used for solving a hyperbolic sine value and a hyperbolic cosine value based on 2 through a generalized hyperbolic CORDIC calculation unit working in a rotation mode so as to obtain an index 2F through additionoperation and shift leftw
