floating point unit (FPU)

A floating point unit (FPU) or numerical processing unit (NPU) is an arithmetic processor that works as a coprocessor for the central

processing unit (CPU) and performs floating point operations. The coprocessor takes over floating-point calculations from the central processing unit and can thus significantly increase the computing speed for mathematical and graphical calculations.

Typical floating-point units are the Intel chips 8087, 80287 and 80387. In modern microprocessors, the floating-point units (FPU) are located on the chip with the CPU.
