DIVISION OF TWO 8 BIT NUMBERS

AIM:
     To perform the division of two 8 bit numbers using 8085.
     
ALGORITHM:
     1) Start the program by loading HL register pair with address of memory location.
     2) Move the data to a register(B register).
     3) Get the second data and load into Accumulator.
     4) Compare the two numbers to check for carry.
     5) Subtract the two numbers.
     6) Increment the value of carry .
     7) Check whether repeated subtraction is over and store the value of product and
        carry in memory location.
     8) Terminate the program.
     

PROGRAM:
               LXI  H, 4150
               MOV  B,M      Get the dividend in B – reg.
               MVI  C,00       Clear C – reg for qoutient
               INX  H
               MOV A,M       Get the divisor in A – reg.
NEXT:     CMP B             Compare A - reg with register B.
               JC  LOOP         Jump on carry to LOOP
               SUB  B             Subtract A – reg from B- reg.
               INR C               Increment content of register C.
               JMP NEXT      Jump to NEXT
 LOOP:    STA 4152         Store the remainder in Memory
               MOV A,C
               STA 4153         Store the quotient in memory
               HLT                  Terminate the program.

OBSERVATION:   

    Input:
F (4150)
FF (4251)
    Output:
01 (4152) ---- Remainder
    FE (4153) ---- Quotient
   
RESULT:
Thus the program to divide two 8-bit numbers was executed.

  1. It's very straightforward to find out any matter on web as compared to textbooks, as I found this piece of writing at this website.

    Take a look at my web page raspberry ketones

  3. hahaha what a dumbass programm check mine out more simple:

    LXI H 3000h
    MOV A M
    INX H
    MOV B M
    MVI C 00h
    L: SUB B
    INR C
    CMP B
    JNC L
    REMAINDER: STA 2051h
    MOV A C
    QUOTIENT: STA 2050h
    HLT

    1. store dividend at 3000h and divisor at 3001h rest is history hehe

    2. its not correct.you are substracting before you comparing the numerator and denominator .
