This includes a floating-point unit (FPU) which offers hardware support for single-precision IEEE-754 floats. It can improve your application's performance if you are performing floating-point operations. Here are some useful points to consider before using the FPU of your processor: High-performance advanced line, Arm Cortex-M4 core with DSP and FPU, 2 Mbytes of Flash memory, 180 MHz CPU, ART Accelerator, Chrom-ART Accelerator, FMC with SDRAM, Dual QSPI, TFT, MIPI-DSI, HW crypto STM32F469IE 32-bit Arm® Cortex®-M4, Single Precision Floating Point Unit (FPU), JTAG / SWD debug interfaces; Peripherals: 104 Configurable GPIO pins 3 UART interfaces 3 I2C interfaces 3 SPI interfaces 2 CAN 2.0B Ethernet 10/100 MAC Full-duplex SpaceWire interface DMA controller (4-Channel) 8-Ch Analog-to-digital converter (12-bit, 600ksps) 2019-03-29 · The answer is that the ARM Cortex-M4F has only a *single precision* (float) FPU, and not a double precision (double) FPU. As such it only can do float operations in hardware but not for double type. The solution in this case is to use float (and not double) constants. If the Cortex-M4 / M7 / M33 / M35P has a FPU, then it is known as the Cortex-M4F / Cortex-M7F / Cortex-M33F / Cortex-M35PF.

Compared with Cortex-M0+, Cortex-M4 performance is about 6 times higher performance. Also, because Cortex-M0+ adopted the 2 stage pipeline, it would not get such faster clock speed as Cortex-M4.
