Study on Double Precision Floating Point Division
Mingyan Yu · Microprocessors · 2011
Based on the IEEE754 standard,a double precision floating point division is designed.The whole design include six parts,which are preprocess,exp_sub,fra_div,format_rounding,overflowing and exception.The fra_div is implemented by five different arithmetic,which include SRT radix-4,improved parallel radix-4,radix-8,radix-16 and radix-256.This paper also analyses the result of the simulation and logic synthesis,and find out they can be used on different places because of their virtue.If considering factors of clock,delay and area,parallel radix-8 and radix-16 arithmetic is perfect choice.
