main data memory

基本解釋

According to the features of main memory data, the data organizing mode and index structure Ttree are introduced.
根據(jù)內(nèi)存數(shù)據(jù)的特點，介紹了其數(shù)據(jù)組織方式和索引結(jié)構(gòu)T樹。
After each data processing step, you set up both a PUT to transfer the data to main memory and a GET to get the next batch of data.
在每個數(shù)據(jù)處理步驟之后，設(shè)置一個 PUT（將數(shù)據(jù)傳輸?shù)街鲀?nèi)存）和一個 GET（獲得下一組數(shù)據(jù)）。
Instead of having multiple directly accessible arguments, you get a pointer into main memory and the SPE has to issue DMA requests to get the pointed-to data from main memory.
它沒有使用多個可直接訪問的參數(shù)，而是使用一個指向主存的指針，SPE 需要發(fā)出 DMA 請求來從主存中獲取指針所指向的數(shù)據(jù)。
