Processors without floating point can use the the fixed-point decoder. But there is no fixed-point (integer-only) encoder. So for your application you'd have to use the reference encoder with software floating point emulation, which is indeed slow. I'd expect a 400 MHz XScale could still do that in realtime, but the best approach is to just build the reference code and see if it works. -r
