8085 Program to Calculate the sum of a series of even numbers

In this program, we will write an 8085 Program to Calculate the sum of a series of even numbers in the 8085 microprocessor with a program flow chart and explanation of the program.

8085 Program to Calculate the sum of a series of even numbers

Program Statement

Write a program in the ALP of 8085 to calculate the sum of a series of even numbers. Assume that the length of the series is stored at memory location D000H and the series itself begins at memory location D001H. Store the result in memory location E000H.

Explanation of Program

  • Initialize the sum to zero. Load the count of numbers in register C. Initialize the pointer to start the series.
  • To check whether the number is even we will AND the number with 01 H. If the result of ANDing is zero it indicates that the number is even. We will add this even number to the initialized sum.
  • Decrement count. Increment source pointer to next location. Continue the process till the sum of all even numbers is found. Store the sum at memory location E000 Н.

Assembly Language Program

MOV C, AInitialize counter
MVI B, 00HSum = 0
LXI H, D001HInitialize pointer
BACK:MOV A, MGet the number
ANI 01 HMask bit-1 to bit-7
JNZ SKIPDon’t add if the number is ODD
MOV A, BGet the sum
ADD MSum = sum + data
MOV B, AStore the result in B register
SKIP:INX HIncrement pointer
DCR CDecrement counter
JNZ BACKIf counter ≠ 0 , repeat
STA E000HStore the sum (result)
HLTTerminate program execution
