Which is the oating point unit in MIPS?

Instead, the oating point operations were carried out on a physically separate chip called the oating point coprocessor or oating point unit (FPU) which in MIPS is called coprocessor 1. The FPU for MIPS has a special set of 32 registers for oating point operations, named $f0, $f1, … $f31. Recall that double precision oats require two words.
