Compared with Cortex-M3 products such as STM32F1/F2, the biggest advantage of STM32F4 is the addition of hardware FPU unit and DSP instructions. At the same time, the main frequency of STM32F4 has also increased a lot, reaching 168Mhz (which can obtain 210DMIPS processing power). STM32F4 is especially suitable for applications that require floating-point operations or DSP processing. It is also called: DSC, which has a very wide range of application prospects.
