Floating-point unit - Wikipedia

    https://en.wikipedia.org/wiki/Floating-point_unit
    Some floating-point hardware only supports the simplest operations: addition, subtraction, and multiplication. But even the most complex floating-point hardware has a finite number of operations it can support – for example, no FPUs directly support arbitrary-precision arithmetic.

Using STM32 Hardware Floating Point Support – VisualGDB ...

    https://visualgdb.com/tutorials/arm/stm32/fpu/
    Aug 24, 2014 · STM32F4 floating-point unit only supports 32-bit floating point numbers (float type, but not the double type). If you are using an older GCC version, it will still try to generate hardware floating-point instructions for operations with double that will cause a …

Instruction Sets Floating Point – Arm Developer

    https://developer.arm.com/architectures/instruction-sets/floating-point
    The Arm architecture provides high-performance and high-efficiency hardware support for floating-point operations in half-, single-, and double-precision arithmetic. It is fully IEEE-754 compliant with full software library support. This page describes floating-support relative to Cortex-A and Cortex-R processors. For information relative to Cortex-M, please refer to our DSP for Cortex-M page.

ARMCC: How to enable the hardware FPU support for Cortex-M7

    http://www.keil.com/support/docs/3716.htm
    Jan 25, 2017 · QUESTION: I know that Cortex-M7 has the option to support a hardware Floating Point Unit (FPU). For instance, I'm using the device Atmel ATSAMV71 that has the hardware FPU support for double floating-point operations. How can I enable this hardware FPU support in my project? ANSWER: For this spec...

Hardware floating point support? NXP Community

    https://community.nxp.com/thread/300751
    Sep 20, 2013 · seems to imply support for hardware floating point. Does the kernel on the micro-SD shipped with i.MX53 QSB support floating point natively? We need just standard IEEE-754 double precision floating point. If not, is there kernel and tool chain with hardware floating point supported? Where. can it be downloaded? Thanks, WayneReviews: 2
