gwdeveloper 275 Posted October 31, 2011 Share Posted October 31, 2011 The FR5739 has the MPY32 hardware multiplier. I would like to use this to speed up the division of a floating point number, float/int. From what I assume, in place of X/Y, I can use X*(1/Y) and use the hardware multiplier. From http://www.ti.com/lit/an/slaa329/slaa329.pdf it would seem that I lose the remainder when doing the division. Is there a faster way to do floating point division with integers but retain accuracy? Currently, I am using the DMA to speed up ADC conversions but then losing cycles during the division. I know I can use the DMA to directly enter the data into the MPY32 registers but then I'll still lose accuracy. Quote Link to post Share on other sites
