Q.5.(25 points) The microoperations in the fetch cycle are as follows: Fetch cycle to: MAR PC 41: MBR Memory PC PC+1 :R MBR TM instruction subtracts 2 times AC from memory location Memory - 2 Nentory + 1 SAT Instruction has direct addressing mode and its opcodeis 10012 Ex: TMI 100H ALU can perform only the following operations: clear AC, increment Ac, decrement AC, shift right Ac, shiftdeft.Ac. 1's complement AC, add MBR. 10 AC. a. Write the microoperations for the execute cycle of SAT inst instruction b. For hardwired control load 1 Write the control signals for the microoperationsin (a). AC . Draw the circuit to be connected to the load input of AC. 6. For microprogrammed control, following microoperation codes are given. Write the binary microcode for the execute cycle of TMI instruction. Assume that the starting address of the TMI routine in the control memoryis 01101000, and Fetch routine starts at address 100000002 microinspruction format: F1 Branch code Branch address F2 microcode 000 001 011 100 101 110 111 address 01101000 01101001 01101010 01101011 01101100 01101101 01101110 01101111 000 001 010 011 100 110 111 Branch code 00 01 10 Mis.cooperation None AC AC-MBR MBR AC MBR Memory AC AC-1 AC she AC ACEO Mis cooperation None MARIRaddt) Memory MBR ACMR AC AC-1 AC sh AC ACAC Branch Unconditional branch Branchit AC=1 Branch if ACCO Mapping
