The 2350 uses an M33 processor core, which has a single-precision
hardware floating-point unit.
For double they have an assist co-processor that speeds up parts of the operations with multiple instructions to do the operation.By using the assist processor for the core function they can significantly reduce the hardware while still getting a speed up since the rest of the code to implement the function needs fewer instructions than a full software implementation.
