Here we will see how to check whether two nibbles of a number are same or not.Problem StatementWrite 8085 Assembly language program to check whether upper nibble and lower nibbles are same or not.DiscussionTo check the nibbles, we have to mask at first. So we need to mask the lower nibble and upper nibble and store them into different registers. The upper nibble will be shifted to the right four bits to make it lower nibble. Then we can check both are same or not. If they are same store 00 at F150 location, otherwise store FF at F150 location.InputAddressDataF050FE AddressDataF050AA Flow ...

While creating vertical slider, we can set custom values as well. Let us take three integer variable and set the int values for min, max as well as the initial value of the slider −int val = 50; int min = 0; int max = 100;Set it to the slider while creating a new slider. Here, we have set the constant to be VERTICAL, since we are creating a vertical slider −JSlider slider = new JSlider(JSlider.VERTICAL, min, max, val);The following is an example to create a vertical slider with custom values −Examplepackage my; import java.awt.Color; import java.awt.Font; import javax.swing.JFrame; import ...

Here we will see how to divide two 16 bit numbers using 8085.Problem StatementWrite 8085 Assembly language program to divide two 16-bit numbers.Discussion8085 has no division operation. To perform division, we have to use repetitive subtraction. To perform 16-bit division, we have to do the same but for the register pairs. As the register pairs are used to hold 16-bit data.The Divisor is stored at location FC00 and FC01, the dividend is stored at FC02 and FC03. After division, the quotient will be stored at FC04 and FC05, and the remainder will be stored at FC06 and FC07.InputAddressDataFC008AFC015CFC025AFC031D Flow Diagram ProgramAddressHEX CodesLabelsMnemonicsCommentsF00001, ...
