Consider the design of a stalling control for a pipelined implementation of the MIPS data path as is shown below:

.

a) Design the Hazard Detection Unit that triggers the Stall Control Mechanism by activating a flag (hazard detected).

b) Define the control lines that need to be used / added to the figure in Problem 1 to enable the stalling mechanism. Explain how your solution stalls the pipe for the exact number of clock cycles needed. Does your solution work when more than one hazard is found in the pipeline?
