Floating - point unit is a special microprocessor circuitry unit that deals with floating - point arithmetic operations , which is widely used in scientific arithmetic , cpu , dsp ( digital signal processing ) and image processing , , the thesis discusses how to implement high - performance floating - point processing unit based on the research of its implementation algorithm and its implementation structure 浮點(diǎn)運(yùn)算單元( fpu )是處理器中專門進(jìn)行浮點(diǎn)算術(shù)運(yùn)算的電路單元,廣泛應(yīng)用在科學(xué)計(jì)算、 cpu 、 dsp和圖象處理。論文從浮點(diǎn)運(yùn)算單元的實(shí)現(xiàn)算法和結(jié)構(gòu)的研究出發(fā),討論如何實(shí)現(xiàn)高性能浮點(diǎn)運(yùn)算單元。
