Design a variant $($explained below$)$ of an unsigned $8-$bit integer restoring divider. In a restoring divider, the divisor is subtracted from the partial remainder; if the resulting partial remainder is negative, the divisor is added back to restore it to an earlier value. In this variant, after subtraction, the sign of the resulting partial remainder is checked; if it is negative, the partial remainder is not updated in the remainder register. Show the design of the Datapath and the controller. Write Verilog code & test bench.
