I am using K65 in life science project. My customer insist to use double.
The built in single precision FPU + DSP will help or not?
Also, what is the impact on the processing speed?
As you know that the K65 with FPU module can only do single precision float operation with hardware, and the DSP instructions in the Cortex-M4 only support integer or fixed point(fractional data) operation. Both the FPU and DSP instruction do not help to operate the double float operation.
Fortunately, the C compilers support double float operation by software simulation, but it takes a long time.
Hope it can help you.
