== Integrated FPUs == In some cases, FPUs may be specialized, and divided between simpler floating-point operations (mainly addition and multiplication) and more complicated operations, like division. In some cases, only the simple operations may be implemented in hardware or [[microcode]], while the more complex operations are implemented as software. In some current architectures, the FPU functionality is combined with [[Single instruction, multiple data|SIMD]] units to perform SIMD computation; an example of this is the augmentation of the [[x87]] instructions set with [[Streaming SIMD Extensions|SSE]] instruction set in the [[x86-64]] architecture used in newer Intel and AMD processors.
