The third instruction increments the memory pointer HL flowchartt and now it will contain h The 4th instruction reads a byte from memory location h and load it in register B.
So micrkprocessor points to h. Type h in the address field iii. If the sum is larger than eight bits FFHit sets the carry flag. The program to add two 8-bit numbers stored in memory is shown below along with the opcode and the physical locations where the program will be loaded in memory.

Press NEXT key, you microproceszor find that the next memory address is automatically displayed v. To execute the program: Probrams output can be verified as: The opcode is The letter ‘E’ will be displayed in the 7-segment address field to indicate that the prgram executed successfully.
Prlgrams the next opcode in the data field of the display vi. The instruction is stored in memory at location, and The two 8-bit numbers are stored in memory location h and h and the result of addition is to be save in memory at location WAP using and verify for: The next instruction at location having opcode 23 increments the HL pair.
The 1st instruction LXI H, h is a 3 byte instruction. The flowchart to add two 8-bit numbers is shown below: Addition of two 8-bit numbers with carry. The theory is explained at the begining of the 1st approach.

Press NEXT key on the kit. To Check the Output: The program given below gives the complete listing of the addition of two 8-bit numbers, the program listed below also shows the the machine opcode and the addresses where the program is to be loaded in memory.
The pcode 7E is stored in memory at location Program Listing for 1st Method using the immediate 8-bit data: The 5th instruction adds the content of register A and B.
The fourth instruction STA h is used to store the result content of accumulator in memory at location h and this instruction having opcode 32 is a 3 byte instruction stored at locationand The last instruction HLT is used to end the execution of the program.

The result 4A is seen in the data field of the 7-segment display. Entering the Program in memory of Programmer kit: Press GO key on the Kit ii.
Type the starting address of the prgram in the address field iii. The 1st instruction MVI A,93h, which is a two byte instruction, loads an immediate byte 93h in the accumulator. 885
Entering the the number in the memory: To check the result: Type the starting address in the address field of the 7-segment display iii. The 2nd instruction reads a byte from memory and loads it in accumulator A.
The opcode for this instruction is 0E and is stored at addressthe 8-bit operand B7h get stored at location The third instruction ADD C has the opcode 81 stored at addressafter this instruction is executed the result get stored in accumulator.
Press NEXT; mkcroprocessor type the opcode in the data field.
