CPUFPU
CPUFPU is a term that refers to the Floating-Point Unit (FPU) within a Central Processing Unit (CPU). The FPU is a specialized part of the processor designed to perform arithmetic operations on floating-point numbers, which are numbers with decimal points. Unlike the main arithmetic logic unit (ALU) of the CPU, which handles integers, the FPU is optimized for the complex calculations required for scientific, engineering, graphics, and multimedia applications.
The FPU was first introduced as a separate coprocessor chip in the early days of personal computing,
Common operations handled by the FPU include addition, subtraction, multiplication, division, square roots, and trigonometric functions,
