CSIS 250 Assembly Language Programming Assignment 03 - AddSub Movsx Add and Sub Signed Operations with Different Data Sizes Create the 403-AddSub MovSX.asm file. Assemble
CSIS 250 Assembly Language Programming Assignment 03 - AddSub Movsx Add and Sub Signed Operations with Different Data Sizes Create the 403-AddSub MovSX.asm file. Assemble and link Copy the completed asm and .exe files to your C:\CSIS250 folder. Command Prompt Type a data segment with these signed byte, word and dword variables: Dunp of offset e .data 1. OF bNume1 SBYTE 127 bNume2 SBYTE -80 Dunp of offset 0 bNume3 SBYTE 32 2. Result SBYTE ? Dump of offset on wNume1 SWORD 32000 3. 0868318 wNume2 SWORD -4096 WNume3 SWORD 256 Dunp of offset 0 wResult SWORD ? SBFC dwumi SDWORD 2eeeeee ; 2.2 million Dunp of offset Be dwume2 SDWORD - 1600000 -1.6 million 5. FBSP dwume3 SDWORD 6e0e dwResult SDWORD ? Durp of offset Be Perform these seven calculations, displaying the indicated results. 6. 8888832 Use the 32-bit registers (EAX and EBX) for all calculations except Dunp of offset e for numbers 4 and 5 below, where the AX register can be used for all operations, since every operand has the 16-bit word site. 7.FFFF9DF1 Use the movex command to preserve the sign when byte and word values (less than word in size) are loaded to a 32-bit register. Load the calculated values in the appropriate variable with the mos operation bResult = Numei + bNum2 . Nume3 display bResult Use 32-bit registers for arithmetic after loading word operands with moves wResult = WNumei + WNum2 - Nume3 display wResult Use 32-bit registers for arithmetic atlet loading word operands with moves 3. dwResult = dwNume1 + dwNumez - dwNume3 display dwResult movess operator is not required to load these 32-bit operands (uemes) (00063101 - 394,000) 4. wResult - 60800 - WNum@1 + 8092 - WNume3 display wResult Use the AX register for all these 16-bit operations (mors not required) 5. WResult - WNume2 - 1 WNume3 + 2480 display wResult Use the AX register for all these operations, use the de operation to subtract from AX) dwResult = bNum2 + WNume - bNum1 + 1 display dwResult Use the ine operation to add to the accumulator (last term) 7. dwResult = -bNumei + dwNume wnumei + 1024 display dwResult Use the seg operation to make the bNumbl value negative after loading into 32-tegister with movest Add these two instruction lines right before the exit command to keep the display window open, call Crlf call WaitMsg 1. 6.
