Hi, I'm using the TWR-K60F120M Tower module. I have the FPU enabled 'FPU with hard vfp passing' and ''c9x' model. I have code that performs 100,000 floating point adds in a loop. The results are as follows:
Kinetis FPU enabled ~120ms
Kinetis No FPU (software) ~500ms
Coldfire MCF52259CAG80 ~150ms
Does these numbers seems resonable. I guess I was expecting the Kinetis to be a magnitude better than the Coldfire (which does not even have an FPU). Can the Kinetis w/FPU be only marginally better that the Coldfire libraries, or do I have something not configured correctly?
