Which stm32 MCU can do fastest DSP, arithmetic & floating point calculation?

[parth kothiya]

I want to make​ robotic arm , CNC controller for this purpose which STM32 is capable to do DSP, arithmetic and floating point calculation Faster (less clock cycle for execution)without much execution code delay?

So interpolation and ​trigonometric functions execute faster and machine axis runs without any leg in calculation.

Suggest me any DSP or MCU ic available which can perform above task​.

Probably the STM32H725/735, has double and single precision FPU, clocks at 550 MHz. The FPU itself does not support transcendental functions directly, for that you'd perhaps look at Intel Atom or similar/equivalent x86 processors.

Well check the STM32G4 which has cordic and Fmac, tainted for motor application. Due to cost to make a chip, float or double seems not always required.... in robotics
