23 Jul 2020 This ultra-low-power dual Arm Cortex-M4 MCU with floating-point unit (FPU) and Bluetooth Low Energy 5.2 (BLE 5.2) extends the device's battery 29 Jun 2010 an optional Memory Protection Unit (MPU). • a Floating Point Unit (FPU) unit, in the Cortex-M4F processor. Page 16. Introduction. ARM DDI 22 Jan 2015 32-bit Cortex.

Description. The STM32F427xx and STM32F429xx devices are based on the high-performance Arm Cortex-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm single-precision data-processing instructions and data types. The FPU in the Cortex-M4 supports: Round to nearest (default) Round toward plus infinity Round toward minus infinity Round toward zero The ARM Cortex-M4 processor with floating-point unit (FPU) has a 32-bit instruction set (Thumb-2 technology) that implements a superset of 16 and 32-bit instructions to maximize code density and performance. 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.

Although the Cortex-M4 seems to be a simple 32-bit core, it supports sophisticated mechanisms, such as exception pre-emption, internal bus matrix and debug units.
