Design Requirements Design a digital system with the following functionality. As shown, the data inputs (A \& B) and output (R) are 4-bits width busses, while Co is only 1-bit width. The M is the control input, which sets the operation of the circuit as indicated in the following table, where M is a bus of width =2. Note:- The (+) represents the arithmetic plus (add) operation. Note:- The (+) represents the arithmetic plus (add) operation. Page 1 of 2 CMPE 263/ Spring 2023 / O Amelle Bedair Design Approach In Logisim, the design should have three levels - Level-1:- A sub-circuit integrating the complete 4-bit adder. Build the 4-bit adder using 1-bit Full Adder. - Level-2:- A sub-eircuit integrating the 4-bit adder sub-circuit and any other required components to complete the circuit. Use any component; e.g. MUX, Decoder, logic gates, etc. - Top-level:- The main working area, only one block with i/o
