Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the calculation device and method oriented to nonlinear functions provided in the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0032] Linear and nonlinear are often used to distinguish the dependence of the function y=f(x) on the independent variable x. A linear function is a linear function. In the coordinate system, the image of a linear function can be expressed as a straight line, which describes the proportional and linear relationship between quantities and quantities, and represents regular and smooth motion in space and time; and Non-linear function, in the coordinate system, its image representation is not a straight line, it describes the relationship between quantities that are not proportional and not in a straight line, and represents non-linear motion and mutation. Although method...

Description

technical field [0001] The invention relates to the field of computing, in particular to a computing device and method for nonlinear functions. Background technique [0002] The nonlinear function is a kind of function form, and the calculation of the nonlinear function is involved in many technical fields. The calculation of nonlinear functions usually includes a series of complex operations such as multiplication, division, exponential and trigonometric functions. The calculation is relatively cumbersome, and usually requires the use of arithmetic logic units and other components to complete the corresponding operations. Correspondingly, the complexity of the design of the operation circuit higher. [0003] The general-purpose arithmetic logic unit used in the prior art, such as the ALU in the CPU, has a series of problems such as low resource utilization, slow execution speed, and large circuit hardware overhead in the calculation of nonlinear functions, which cannot mee...
