Implement an 8-bit carry-lookahead adder and an 8-bit carry-ripple adder using CLA-4 \& CLG-4 modules. Identify the critical path in the adders and determine expressions for propagation delay in both types of adders in terms of module delays. Discuss the implementation of a 4-bit arithmetic unit having five different functions - ADD,ADDC,SUB,CS \& INC. Derive expressions for the various control signals and show the implementation of the control logic block to generate
