數(shù)據(jù)交換：這是指實(shí)現(xiàn)CPU與控制器之間、控制器與設(shè)備之間的數(shù)據(jù)交換。對(duì)于前者，是通過數(shù)據(jù)總線，由CPU并行地把數(shù)據(jù)寫入控制器，或從控制器中并行地讀出數(shù)據(jù)；對(duì)于后者，是設(shè)備將數(shù)據(jù)輸入到控制器，或從控制器傳送給設(shè)備。為此，在控制器中須設(shè)置數(shù)據(jù)寄存器。
狀態(tài)說明：標(biāo)識(shí)和報(bào)告設(shè)備的狀態(tài)控制器應(yīng)記下設(shè)備的狀態(tài)供CPU了解。例如，僅當(dāng)該設(shè)備處于發(fā)送就緒狀態(tài)時(shí)，CPU才能啟動(dòng)控制器從設(shè)備中讀出數(shù)據(jù)。為此，在控制器中應(yīng)設(shè)置一狀態(tài)寄存器，用其中的每一位來反映設(shè)備的某一種狀態(tài)。當(dāng)CPU將該寄存器的內(nèi)容讀入后，便可了解該設(shè)備的狀態(tài)。

接收和識(shí)別命令：CPU可以向控制器發(fā)送多種不同的命令，設(shè)備控制器應(yīng)能接收并識(shí)別這些命令。為此，在控制器中應(yīng)具有相應(yīng)的控制寄存器，用來存放接收的命令和參數(shù)，并對(duì)所接收的命令進(jìn)行譯碼。例如，磁盤控制器可以接收CPU發(fā)來的Read、Write、Format等15條不同的命令，而且有些命令還帶有參數(shù)；相應(yīng)地，在磁盤控制器中有多個(gè)寄存器和命令譯碼器等。
地址識(shí)別：就像內(nèi)存中的每一個(gè)單元都有一個(gè)地址一樣，系統(tǒng)中的每一個(gè)設(shè)備也都有一個(gè)地址，而設(shè)備控制器又必須能夠識(shí)別它所控制的每個(gè)設(shè)備的地址。此外，為使CPU能向(或從)寄存器中寫入(或讀出)數(shù)據(jù)，這些寄存器都應(yīng)具有*的地址。
