Draw the gates: How many XOR gates are required to generate the parity bit for an eight-bit data value? How many XOR gates are required to check the parity bit for an eight-bit data value (plus one parity bit)?

Give all gates output

show how to design a 8-bit Function Unit Combining Arithmetic Logic Unit (ALU) and a Shifter that can perform the operations given in table 1 below. Use X and Y as 8 bits input and F as 8 bits output as shown in Figure 1. S0,S1,S2 and S3 represent the selction code in the operation set table Three statue bits V (over flow), C (carry), N (negative) and are related to arrithmatic operations and statue bit Z (zero) is relataed to both arrithmatic and logic operation. Test your designed Function Unit with necessary tables.
