An $8bit$ data path is to be set up using two $4bit$ ALU's and suitable multiplexers. The ALU's accept two operands $A$ and $B$ on which a total of $16$ operations can be performed. The operand $A$ is from one of two registerarrays ... on a bus. List the data path control signals, and estimate the minimum width of a signal microcode word needed for the generation of these signals.
