Pipeline Simulation For each of the modules from Figure 4.51 (page 304 of P&H) that are listed in the table below, specify what the inputs and outputs are in each cycle for the following code. You do not need to specify values for those modules, inputs, or outputs not listed in the table. Manually simulate (i.e., fill out the table) until the sw has completed (i.e., left the write-back stage). [Hint: the table already has the first couple of cycles filled out. If a value depends on an instruction before or after the code below, report it as X.]
