Using Logisim implement the following circuit. The outputs of four registers, RO, R1, R2 and R3 are connected through 4-1 Mux to the input of fifth Register. Each register is eight bits long. The required transfers are dedicated by four timing variables TO through T3 as follows: TO: R5RO T1: R5ERI T2: R5R2 T3: R5ER3 The timing variables are mutually exclusive, which means that only one variable is equal to 1 at any given time, while the other three are equal to 0. Draw a circuit diagram on Logisim showing the hardware Implementation of the register transfers. Include the connections necessary from the four timing variables to the selection inputs of the multiplexers and to the load input of register R5
