• Fixed-point multiplication
    I want to multiply two fixed point numbers. After the multiplication I have to shift the result so that the binary point is correct. Example: int a; int b; int c; c = (a * b) >> 10 The multiplication...

  • 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...

  • How high is the precision of fixed-point processors for floating-point numbers?
    Recently I came into contact with the DSP processor. I have two questions about the fixed-point processor processing floating-point operations. I developed it in C language. A 16-bit processor. Two floating...
