The U54 FPU provides full hardware support for the IEEE 754-2008 floating-point standard for 32-bit single-precision and 64-bit double-precision arithmetic. The FPU includes a fully pipelined fused-multiply-add unit and an iterative divide and square-root unit, magnitude comparators, and float-to-integer conversion units, all with full hardware support for subnormals and all IEEE default values.
