Register Transfer Language is a language which is used to transfer data from one register to another register and also describe the sequence of micro-operations.But the description of micro-operation is too lengthy and difficult so we used symbolic notations.This symbol of notation describe by R.T.L.

Symbol                    Describe                    Examples
1)Letters and        Register Name        R1,R2,R3.....
Numerals 

2)Parenthesis       Part of Register      R1(0-7)
                                                                          Dr(11-5)

3)Arrow's               data transfer fr-      R1<--Ac
                                   om one place to
                                   another.

4)Comma(,)          Separate 2 micr-
                                   ooperations.
                                  

5)Control Signal  It is denoted as le-  P:R1<--R2
                                    tter and colon.  


Let us take an example,Show conditional statement by 2 register transfer statement with control function.

if(P==1) then (R1<--R2)
else
if(Q==1) then (R1<--R3)

Sol.  P: R1<--R2
          P'Q: R1<--R3
