Q. Sequential Execution of Instructions in RISC?

Let's describe pipelining in RISC with an illustration program execution sample. Take the given program (R denotes register).

LOAD R_A                               (Load from memory location A)

LOAD R_B                               (Load from memory location B)

ADD R_C ,R_A , R_B                    (R_C = R_A + R_B) )

SUB R_D , R_A , R_B                    (R_D = R_A - R_B) 

MUL R_E , R_C , R_D                   (R_E = R_C × R_D)

STOR R_E                                 (Store in memory location C)

Return to main.
