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. Note: The Cortex-M series includes three new 16-bit Thumb-1 instructions for sleep mode: SEV, WFE, WFI. VA41620 – Radiation Hardened Arm® Cortex®-M4 w/ FPU MCU 32-Bit ARM® Cortex®-M4 RADIATION HARDENED Microcontroller This rad-hard Hi-Rel MCU is manufactured with HARDSIL® technology offering superior radiation performance and latch-up immunity. For Cortex-M4, the optional FPU is 32-bits, i.e. single precision FP. Note that this means that double precision (i.e.

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).
