| Unit | Time |
|---|---|
| Adder | 257.86 ns |
| Logic Unit | 101.14 ns |
| Shifter | 186.31 ns |
| Multiplier | 1050.40 ns |
| Control Unit | 151.04 ns |
| 8-bit Register | 38.88 ns |
Therefore, the critical path inside the chip would include the adder, the control unit, and the input register. This sums to 447.78 ns. We can run our chip at speeds less than 2.23 MHz.
