Question: Write a combined microroutine that can implement the BGT (Branch if > 0), BPL (Branch if Plus), and BR (Branch Unconditionally) instructions. The branch conditions

Write a combined microroutine that can implement the BGT (Branch if > 0), BPL (Branch if Plus), and BR (Branch Unconditionally) instructions. The branch conditions for the BGT and BPL instructions are Z + (NV) = 0 and N = 0, respectively. What is the total number of microinstructions required? How many microinstructions are needed if a separate microroutine is used for each machine instruction?
