All function operations are implemented by the hardware circuit by adopting a segmental variable parameter curve fitting mode; the scalar floating point operation accelerator comprises a main control processor, an operator, an interface control circuit, an interface register and an instruction part, wherein the interface control circuit is connected with the interface register; the instruction part is connected with the interface register; the operator is connected with the interface register; the main control processor is connected with the interface control circuit; the operator performs quadratic curve fitting processing on a single-variable function and performs binary quadric curved surface fitting processing on a double-variable function; and during fitting processing, the functions are subjected to segmental fitting.

Description

technical field [0001] The invention relates to an arithmetic unit, in particular to an arithmetic unit which uses a hardware circuit to realize scalar floating point calculation. Background technique [0002] The so-called scalar floating-point number refers to a floating-point number, not a set of floating-point numbers. Scalar floating-point calculations are generally processed by high-level language function libraries, which take a long time and are slow to process. Therefore, hardware circuits are often used to complete such calculations in single-chip or embedded systems to speed up calculations. In order to save more system resources and chip space occupied by such computing circuits, generally only one or two linear function computing circuits are used. However, in the high-end application fields of embedded systems, such as industrial control, POS machines, network equipment, image In applications such as processing, strong data processing capabilities are required...
