physical memory location

基本解釋

For example, one PPE-side mailbox register appears as a write-only physical memory location.
例如，一個 PPE 端的郵箱寄存器會作為一個只寫的物理內(nèi)存位置出現(xiàn)。
Past that is unmapped memory -- memory for which no corresponding physical location has been assigned either in RAM or on disk.
該地址之后是未被映射的內(nèi)存 —— 用于在 RAM 或者硬盤中沒有分配相應(yīng)物理位置的內(nèi)存。

This way we did not have to care about the physical location of our data within memory, we simply used its identifier whenever we wanted to refer to our variable.
這樣我們就不必關(guān)心我們的數(shù)據(jù)在內(nèi)存中的實際物理位置，我們每次想引用我們的變量時只需使用它的標(biāo)識符即可。
