Explanation / Answer

please rate - thanks I'm really not enjoying this and I don't have to do it, I onlystarted it since you asked, but it should give you an idea. to get the controls and ALU you have to pack, the way Iunpacked good luck #include intRegDst,ALUSrc,MemtoReg,RegWrite,MemRead,MemWrite,Branch,ALUOp1,ALUOp0; int sub,c1,c0; inst[32]={0}; unsigned int of,ff,cont,alu; void control(); void alu_control(); void unpackop(); void unpackff(); main (){ int i;    printf("hmwrk5: "); printf("op field: "); scanf ("%x",&of); unpackop(); printf("function field: "); scanf("%x",&ff); unpackff(); control(); printf("control signals: %9x ",cont); printf("alu control: %3x ",alu); getch(); return 0; } void unpackop() {unsigned int mask=0x100000; int i; for(i=31;i>=26;i--)       {if((of&mask)==mask)           inst[i]=1;        mask=mask>>4;        } for(i=31;i>=26;i--)        printf("%d ",inst[i]); printf(" "); } void unpackff() {unsigned int mask=1; int i; for(i=0;i
