Execution of a full Instruction:

Regard as the instruction:

Add (R3), R1

Executing this particular instruction needed the below described actions:

a) Fetch the instruction

b) Fetch the primary operand (the contents of the memory location pointed to by R3)

c) Perform the addition operation

d) Load the result into R1register

Control Sequence for instruction Add (R3), R1:

PCout, MARin, Read, Select4, Add, Zin
Zout, PCin, Yin, Wait for the MFC
MDRout, IRin
R3out, MARin, Read
R1out, Yin, Wait for MFC
MDRout, Select Y, Add, Zin
Zout, R1in, End

Branch Instructions:

PCout, MARin, Read, Select4, Add, Zin
Zout, PCin, Yin, Wait for the MFC (WFMC)
MDRout, Irin
offset_field_of_IRout, Add, Zin
Zout, PCin, End
