• Speed up floating point math
    I know that Keil has spent lots of time optimizing the floating point routine, but we are hitting a performance wall in our application and we are looking for anything that will keep us in the current...
  • KEIL versus IAR floating point math...
    I've been trying to figure out why the below math benchmark code appears to run about twice as fast on the same eval board, depending on whether I use KEIL or IAR tools to build the project. The pulse...
  • On Cortex-M4F microcontrollers: is fixed point math faster or floating point?
    Hi, I am using S32K14x controllers (Coretx-M4F). It has floating point math unit. I need to perform many mathematical operations as fast as possible. Which will be faster: fixed point q16 or fixed point...
  • Floating Point
    How can I deny a number floating point without utilizat some mathematical operation? How can I take the first 8 bits of the number floating point, those but significant (MSB) or the bit but significant...
