Description

I'm trying to design my own FPU but I find that supporting denormal numbers would add huge delay to the hardware logic. So I'm wondering is recoded format able to reduce some delay when dealing with denormal numbers ? Since I find that the biggest difference between recoded format and ieee754 is in denormal numbers. Could you please share some information, like the synthesis results ? Thanks!
