Consider the following MARIE Assembly program: label opcode operand hex X LOAD 1107 100 101 SUBT Y 4108 102 SKIPCOND 400 8400 103 JUMP END 9106 104 LOAD X 1107 105 ADD Y 3108 106 END HALT 7000 107 X DEC 3 0003 108 Y DEC 8 0008 What's the value in the AC register after the program executes the SUBT instruction? Express your answer in Decimal

Given the instruction: LD RO, X005 If the instruction is stored in memory at x3000, how will data be moved? Data at address x3005 will be loaded into RO Data in RO will be stored into memory at x3006 Data at address x3006 will be loaded into RO Data in RO will be stored into memory at x0005

20 LDA 50 21 SUB 51 50 100 51 200 Choose the contents of the registers: PC, MAR, MDR, IR, A at the end of fetch-execute cycle for instruction 20: PC MAR MDR IR A

Based on the diagram below, what is the result for register DX after executing the mnemonic opcode/operand instructions? MOV AX, 200h MOV BX, 100h MUL BX АХ BX DX AX CF OF 200h X 100h The resulted DX is 00A2. a. The resulted DX is 0002. The resulted DX is 0012. OC. The resulted DX is 0022. Od.
