(FPU) In computing, a specially designed chip that performs floating-point calculations. Computers equipped with an FPU perform certain types of applications much faster than computers that lack one. In particular, graphics applications are faster with an FPU.
Some microprocessors, such as the Intel 80486, have a built-in FPU. With other microprocessors, an FPU can usually be added by inserting the FPU chip on the motherboard.
Drugi naziv za matematički koprocesor. Posebno se odnosi na matematički koprocesor koji je ugrađen u mikroprocesor, što je slučaj sa procesorima 486 i Pentijum.
