WebNov 12, 2008 · Use fixed-point when the hardware doesn't support floating-point or the hardware implementation sucks. Also beware when making classes for it. Something you think would be quick could actually turn out to be a dog when it comes to profiling due to (un)necessary copies of classes. That is another question for another time however. Share WebMar 29, 2024 · Not only floating point operations have numerical problems, they can lead to performance problems as in the following (simplified) example: ARM designed the Cortex-M4 architecture in a way it is possible to have a FPU added. For example the NXP ARM Cortex-M4 on the FRDM-K64F board has a FPU present.

WebMar 6, 2024 · In most projects the cost of the device is the driving factor that it makes floating-point processing prohibitively expensive, and therefore fixed-point is usually … WebFixed point is only really worthwhile when you don't have an FPU - most modern x86 CPUs have two FPUs so there is nothing to be gained from using fixed point, and performance may even be significantly worse with fixed point.

On any iOS device that supports iOS 9, using short floats for DSP computation (multiply-accumulates) for most DSP algorithms is as fast or faster than using 32-bit scaled integers.
