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.

Bisection Method – Algorithm, Flowchart and Code in C

Bisection Method Illustration

Bisection Method Illustration

The bisection method is one of the simplest and most reliable of iterative methods for the solution of nonlinear equations. This method, also known as binary chopping or half-interval method, relies on the fact that if f(x) is real and continuous in the interval a < x < b, and f(a) and f(b) are of opposite signs, that is,

f(a)*f(b) < 0

then there is at least one real root in the interval between a and b.


How to change upload limit of WordPress hosted on Azure VM

In this tutorial, you’ll learn how to change upload limit of WordPress hosted on Azure VM (Virtual Machine). Recently, after hosting a WordPress website on Azure Virtual Machine (Linux), I was trying to upload media and files to the WordPress site.
