8085 Program to Multiply two 8 bits numbers
In this program, we will see how to multiply two 8-bit numbers using 8085 microprocessor.Problem StatementWrite 8085 Assembly language program to multiply two 8-bit numbers stored in a memory location and store the 16-bit results into the memory.DiscussionThe 8085 has no multiplication operation. To get the result of multiplication, we should use the repetitive addition method. After multiplying two8-bit numbers it may generate 1-byte or 2-byte numbers, so we are using two registers to hold the result.We are saving the data at location 8000H and 8001H. The result is storing at location 8050H and 8051H.InputAddressData......8000DC8001AC......Flow DiagramProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80LXIH, 8000HLoad first ...

In the Central Nervous System, Human Brain is the main organ. It comprises of the cerebrum, the brain stem, and the cerebellum. It controls the vast majority of the body activities, processing, incorporating, and coordinating the data it gets from the sensory organs and deciding the instructions sent to the rest of the body. The mind is contained in and secured by the skull bones of our head.The human cerebrum is mainly made up of neurons, glial cells, and veins. Interneurons, pyramidal cells including Betz cells, motor neurons, and cerebellar Purkinje cells are the various types of neurons. Betz cells are ...
Read MoreProgram to Divide two 8 Bit numbers in 8051 Microprocessor
Here we will see the division operation. This operation will be used to divide two 8-bit numbers using this 8051 microcontroller. The register A and B will be used in this operation. No other registers can be used for division. The result of the division has two parts. The quotient part and the remainder part. Register A will hold Quotient, and register B will hold Remainder.We are taking two number 0EH and 03H at location 20H and 21H, After dividing the result will be stored at location 30H and 31H.AddressValue …20H0EH21H03H …30H00H31H00H …Program MOV R0, #20H ; set source address 20H ...

Here we will see how to multiply two 8-bit numbers using this 8051 microcontroller. The register A and B will be used for multiplication. No other registers can be used for multiplication. The result of the multiplication may exceed the 8-bit size. So the higher order byte is stored at register B, and lower order byte will be in the Accumulator A after multiplication.We are taking two number FFH and FFH at location 20H and 21H, After multiplying the result will be stored at location 30H and 31H.AddressValue …20HFFH21HFFH …30H00H31H00H …Program MOV R0, #20H ; set source address 20H to R0 ...

Now, in this section we will see how to subtract two 8-bit numbers using 8051 microcontroller. The register A (Accumulator) is used as one operand in the operations. There are seven registers R0 – R7 in different register banks. We can use any of them as second operand.We are taking two number 73H and BDH at location 20H and 21H, After subtracting the result will be stored at location 30H and 31H.AddressValue …20H73H21HBDH …30H00H31H00H …Program MOV R0, #20H ; set source address 20H to R0 MOV R1, #30H ; set destination address 30H to R1 ...
