2018-11-13 · Maxim’s Arm Cortex-M4 family of MCUs with floating point unit (FPU) are ultra-low power, cost-effective, and designed for battery-powered applications Maxim’s MAX32652 is a memory-scalable microcontroller designed specifically for high-performance battery applications.

The STM32F4xx series is based on a Cortex-M4 core. 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:

The CPACR characteristics are:. The Cortex-M4 FPU is an implementation of the single precision variant of the ARMv7-M Floating-Point Extension (FPv4-SP). It provides floating-point  The Cortex-M architectural HAL provides support for a hardware Floating Point Unit (FPU) if one is present, to provide accelerated floating point math operations. The other key feature that separates Cortex-M4 processors from less advanced ones is the addition of a Floating Point Unit (FPU). An FPU is a separate processor  Does the ARM core include an FPU? Cortex-M4F and Cortex-M7F cores do. How much Flash memory and RAM does the target device has? e.g.
