Can someone help me with a pretty simple assembly language pipelining question in my computer organization class?? Im a little confused on the pipelining concept. Thanks

Q. 6. Suppose you have a non-pipelined DLX computer where every instruction takes five cycles to execute. You run the following program on the machine where the initial values of R3 and R7 are 80 and 0 respectively (2+2+2+5+3+2+2+1-19 points). loop: ADDI R7, R7,1 SW 0(R3), R7 SUBI R3, R3,4 BNEZ R3,_loop Q. 6.
