4. The following figure displays a computer system with registers outputs and external input connected to an ALU with two input busses A and B. The register inputs and external output are connected to the output of the ALU. Each register size is 12 bits. The control word supports 32 operations a Insert each section size in bits of the 3 address control word of 32-bit total size b Insert each section size in bits of the 2 address control word of 15-bit total size. o Formulate the 3-address control word to execute: R3 R2+ R1'+1(use Table.4.1 for OPR by converting it to binary bits) d- Formulate the 2-address control word to execute: R1 R2+R1+1,(use Table.4.2 for OPR by converting it to binary bits) Table.4.1 (3 address format) Table.4.2 (2 address format) Transfer A Increment A TransferA D+ A Add ATB Subtract A Decrement A Subtract A-DDA0 Decrement A- D-A- AND A wth D D ND AND A with B D 10R A with D TRORA with D IDeMD IDtAeo XOR A with B D AOB 4.
