10.3.7. Floating Point Unit

Each Arm* Cortex*-A9 processor includes full support for IEEE-754 floating point operations.

The floating-point unit (FPU) can execute half-, single-, and double-precision variants of the following operations:

  • Add
  • Subtract
  • Multiply
  • Divide
  • Multiply and accumulate (MAC)
  • Square root

The FPU also converts between floating-point data formats and integers, including special operations to round towards zero required by high-level languages.
