Let's Program the Transistors
In an earlier article, we learned about 2’s complement addition. In this article, we will discuss how to perform 1’s complement addition. We will consider the same example that is taken for the 2’s complement addition. Important Rule: Add the two numbers using the basic rules of binary addition. If there is a carry out…

Many a time, overflow in a binary addition seems like a final carry generation. However, overflow leads to an incorrect sum, whereas carry does not. This is a little confusing if not understood correctly. So, let’s understand the overflow concept clearly. Imagine you have a half-tea-filled cup. Your friend has a jar with some amount…
8085 is a very basic microprocessor with the capability of limited arithmetic and logical operations. It has dedicated arithmetic instructions for addition, subtraction, increment and decrement. If we want to perform a multiplication operation then we need to write a program for it. Multiplication is nothing but repeated addition. This post presents assembly language program…
This post would present you with assembly language program for 16-bit addition in 8085 microprocessor. The following Hex Code is a generic one for both no-carry and carry generation situation. // Manually store 1st 16-bit number in the memory location 2000H & 2001H in reverse order // For Example 1st number = B349H; i.e, 2000<-49H…
This post would present you with assembly language program for 8-bit addition in 8085 microprocessor. We will consider 2 different cases of addition (i) Addition of two 8-bit numbers generating no carry (ii) Addition of two 8-bit numbers generating a carry Addition of two 8-bit numbers generating no carry // Manually store 1st number in the memory…
