Assume that each memory location stores two ASCII characters.Memory LocationValue Stored100101102 3.(2 points) Draw the block diagram for the hardware that implements the following:y + xz: AR  BR + CRwhere AR, BR and CR are n-bit registers and x, y, and z are control variables. Include the logic gates for the control function and a block labeled ‘adder’ for the addition function. (Remember that that the symbol + designates an OR operation in the control function, but an arithmetic plus in a microoperation.) 4.
