A data type is an attribute that specifies the type of data that the object can hold : integer data , character data , monetary data , date and time data , binary strings , and so on 數(shù)據(jù)類型是一種屬性,用于指定對(duì)象可保存的數(shù)據(jù)的類型:整數(shù)數(shù)據(jù)、字符數(shù)據(jù)、貨幣數(shù)據(jù)、日期和時(shí)間數(shù)據(jù)、二進(jìn)制字符串等。
Transformations can also include error outputs , which provide information about the error that occurred , together with the data that failed : for example , string data that could not be converted to an integer data type 轉(zhuǎn)換還可以包含錯(cuò)誤輸出,它們提供關(guān)于發(fā)生的錯(cuò)誤以及失敗的數(shù)據(jù)的信息,例如,無法轉(zhuǎn)換為整數(shù)類型的字符串?dāng)?shù)據(jù)。
After comparing several kinds of data type operating time , the integer and long integer data are used to reduce the data calculating time . so it satisfies the device ' s real time request quite well 通過對(duì)幾種數(shù)據(jù)類型各種運(yùn)算的運(yùn)算時(shí)間比較,確定在本系統(tǒng)中所有參數(shù)采用整型數(shù)或長(zhǎng)整型數(shù)的計(jì)算方法,優(yōu)化了程序的設(shè)計(jì),在保證計(jì)算精度的前提下更好的滿足裝置對(duì)實(shí)時(shí)性的要求。
Ck510 only handles integer data and uses dhrystone , a famous benchmark for measuring integer computing performance , to evaluate its performance . in ck510 project i was in charge of iu ( integer unit ) design . iu consists of three pipeline stages : register file , execution and write back 我的研究課題就是c - core中整數(shù)單元的設(shè)計(jì)研究,為了實(shí)現(xiàn)c - core的總體目標(biāo),優(yōu)化整數(shù)單元的邏輯設(shè)計(jì),探索和實(shí)現(xiàn)提高處理器的cpi和降低整數(shù)單元的功耗的技術(shù)是這次研究課題的主要目標(biāo)。
