[4 Marks CO1, PO1, C2) b) Explain the the multiprocessor syste of the Non-Von Neuman Machine architecture. 15 Marks C01, PO1, C2) c) Arithmetic Logic Unit (ALU) is a digital circuit that performs Arithmetic operations. By using the last number in your ID number (Example: TG1800X) (if X=0,1,2,3,4, choose Y=4) and (if X=5,6,7,8,9. Choose Y=7) Perform Y multiply -4 by using booth algorithm.. ii) Perform Y divide -2 by using restoring division algorithm. [16 Marks CO2, PO3, C3]
