The primary contents and innovations of this article are introduced below . in order to take advantage of the high speed of calculation , and at the same time , improve the accuracy and dynamic - range of the algorithm , three kinds of multi - input floating point adder algorithm ( fpa ) are summarized and a high - performance multi - input fpa structure is put forward with a self - defined floating point format . the performance of the high - performance structure on calculation speed and logic resource consuming is better than the normal structure 論文的主要工作及創(chuàng)新點如下:為了充分利用fpga處理速度快的特點,同時盡量提高算法的精度及動態(tài)范圍,本文在對浮點加法器算法進(jìn)行深入研究的基礎(chǔ)上,規(guī)納總結(jié)了三種不同的多輸入浮點加法器算法,并創(chuàng)造性地提出了一種高效的多輸入浮點加法器結(jié)構(gòu)及一種適合于fpga實現(xiàn)的自定義浮點數(shù)格式,這種高效的結(jié)構(gòu)在所需的邏輯資源和運算速度上均遠(yuǎn)優(yōu)于傳統(tǒng)的多輸入結(jié)構(gòu)。
