I'll start with what I'm about.I have relatively complex mathematics in flat or double I wonder how long these calculations will take
If I didn't need an FPU, I would use the STM32F103 for simulations, for which a simulator is also available with peripherals https://developer.arm.com/documentation/ka002225/latest
Unfortunately, there is no complete simulator including peripherals for the STM32F303 (Cortex M4).I'm not interested in peripherals, as long as the FPU is not considered a peripheral and Core M4 simulation is supported accordingly https://www2.keil.com/mdk5/simulation
Question. How can I achieve this so that I can simulate part of the code, for example, for the STM32F303, i.e. the CortexM4 core, the code in which is not about peripherals, but purely about calculations?
