Assembly Language Program to Obtain the Largest of the Contents in a Memory Location

Question: Write an assembly language program to obtain the largest of the contents of memory location 2222H and 2223H and store the number to next memory location i.e. 2224H


Introduction to Assembly Language with Examples

Assembly programming language is a language closer to what machines can understand. Assembly language is an example of low level language. In an assembly language, each machine language instruction is assigned a code. So, instead of having to remember a string of 0’s and 1’s, the programmer would only need to remember short codes like ADD, SUB, DIV, JMP, MOV, HALT, GO called mnemonics.


Assembly language program to count the number of 1’s in a byte stored in memory location 2000H

Write an assembly language program to count the number of 1’s in a byte stored in memory location 2000H.

Step 1: Point to memory location 2000H

Step 2: Load register A (Accumulator) with the content of memory location

Step 3: Set a counter to loop through each bits of number, Say C

Step 4: Set a counter to store the number of one’s (1’s) in the byte, Say B

Step 5: Rotate the content of accumulator to left through carry

Step 6: If no carry found from Step 5 then jump to Step 8

Step 7: Else increase the counter B by one (if carry found)

Step 8: Decrease counter C by one

Step 9: Until the value at counter C is 0 repeat from Step 5

Step 10: Terminate the program.
