Considering the following sequence of MIPS code, your task is to use pipelining building blocks to execute this set of instructions.

add $R2, $R0, $R0
lw $R1, 0($R2)
addi $R3, $R1, 20
add $R1, $R2, $R0
or $R1, $R2, $R0

a. How many stall cycles would occur in a MIPS pipelining without Pipeline Forwarding? Using the pipelining building blocks to explain your result.
b. How many stall cycles would occur in a MIPS pipelining with Pipeline Forwarding? We assume that Pipeline Forwarding exists between DM-to-ALU, ALU-to-ALU, and DM-to- DM. Using the pipelining building blocks to explain your result.

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately
