Question
Answer the following questions considering pipelining: You have a system with a
single memory port, but a separate port is available dedicated to the stack. So you need to be
careful when accessing the memory. Consider the following pipelining scenario to identify the
types of the hazards and indicate the numbers of related instructions (which pair of instructions)
along with the reason why they occurred. Note that out instruction uses an I/O port isolated
from the memory.
