We can use an assignment statement (x := value) to describe what the RTM circuit does. Which of the following statements is the circuit NOT able to execute in one clock cycle? Select one: O a. R3:= 7 O b. R2 := 4 + R3 C.RO := RO + R1 d. R1 := R2 + R3 What might happen if the clock runs slower than it should? Select one: a. Glitches would be impossible O b. Programs running on the circuit might be unnecessarily slow O c. The logic gates would have a longer gate delay O d. The circuit could get the wrong answers Suppose a demultiplexer is being used to control a register file with 16 registers. Then the number of address bits that must be input to the demultiplexer is
