INTRODUCTION TO MICROPROCESSOR Aim. To study the microprocessor the microprocessor and not accessible to programs. g) Flags. ISIS-II / MACRO ASSEMBLER OPERATOR'S MANUAL, When you .. the least expensive tools available for microprocessor programming. MICROPROCESSOR • Reference Book: – Ramesh S. Goankar, “ Microprocessor Architecture, Programming and Applications with ”, 5th Edition.

Development system[ edit ] Intel produced a series of development systems for the and , known as the MDS Microprocessor System. The original development system had an processor. Later and support was added including ICE in-circuit emulators.

It is a large and heavy desktop box, about a 20" cube in the Intel corporate blue color which includes a CPU, monitor, and a single 8-inch floppy disk drive. Later an external box was made available with two more floppy drives.

This unit uses the Multibus card cage which was intended just for the development system. A surprising number of spare card cages and processors were being sold, leading to the development of the Multibus as a separate product.

The later iPDS is a portable unit, about 8" x 16" x 20", with a handle. It can also accept a second processor, allowing a limited form of multi-processor operation where both processors run simultaneously and independently. The screen and keyboard can be switched between them, allowing programs to be assembled on one processor large programs took awhile while files are edited in the other.

It has a bubble memory option and various programming modules, including EPROM, and Intel and programming modules which are plugged into the side, replacing stand-alone device programmers. All data, control, and address signals are available on dual pin headers, and a large prototyping area is provided.

These instructions are written in the form of a program which is used to perform various operations such as branching, addition, subtraction, bitwise logical , and bit shift operations. More complex operations and other arithmetic operations must be implemented in software. Inserting string in a given array of characters Deleting string in a given array of characters Multiply two eight bit numbers with shift and add method Divide bit number with 8-bit number using shifting technique Sub routine to perform the task of DAA Program to test RAM Program to generate fibonacci number Generate a delay of 0.

Data transfer from one memory block to other memory block.

Find the factorial of a number Find the Square Root of a given number Split a HEX data into two nibbles and store it 3 Add two 4-digit BCD numbers Subtraction of two BCD numbers Generate and display binary up counter Generate and display BCD up counter with frequency 1Hz Generate and display BCD down counter Generate and display the contents of decimal counter Debug the delay routine b.

Binary to BCD conversion Find the 7-segment codes for given numbers HEX to Decimal conversion HEX to binary conversion c. Output byte from SOD pin Generate square wave from SOD pin Transmit message using Receive message using II.

Microprocessor Programs

Traffic Light Control Stepper Motor Control Keyboard interface key-matrix-keyboard Interfacing of eight 7-segment digits Interfacing of 4x4 matrix keyboard and 4 digit 7 segment display Roll a message - 'HELL' In program 1 direct addressing instruction is used, whereas in program 2 indirect addressing instruction is used.

MOV B, M register. In Program 1, direct addressing instructions are used, whereas in Program 2, indirect addressing instructions are used.

The most significant eight bits of the two numbers to be added are in memory locations H and H. Store the result in memory locations H and H with the most significant byte in memory location H Program - 5.

The most significant eight bits of the two numbers are in memory locations H and H. Store the result in memory locations H and H with the most significant byte in memory location H.

Assume the least significant digit is stored at H. Get the original BCD number : Mask higher nibble : Store the result : Terminate program execution 15 12 Statement:Read the program given below and state the contents of all registers after the execution of each instruction in sequence. Assume that data is in register C.

Assume that data is in BC register pair. Assume data is in the HL register pair. The length of the series is in memory location H and the series begins from memory location H. Consider the sum to be 8 bit number. So, ignore carries.

Store the sum at memory location H. Consider the sum to be 16 bit number. Store the sum at memory locations H and H. Store the quotient in memory locations H and H and remainder in memory locations H and H.

The length of the block is in memory location H and the block itself begins in memory location H. The length of the block is in memory location H and the block itself starts from memory location H. Store the maximum number in memory location H.

Assume that the numbers in the block are all 8 bit unsigned binary numbers. The length of the list is in memory location H and the series itself begins from memory location H. Assume the sum to be 8 bit number so you can ignore carries and store the sum at memory location H.

Assume the sum to be bit. Assume byte is in the C register and starting address of the list is H. Writing machine language program is quiet troublesome and leads to error.

This is called assembly language. Program written in assembly language has to be translated into a machine language. A translator, which translates an assembly language program into a machine language program is known as assembler. These programs which are written in English are converted into binary language using program called a compiler or interpreter. The specific operation desired is written in the graphic symbols.

The common flow chart symbols are, It shows direction of program execution. Each code is then has to be stored in memory location. The beginning address is generally xyoo, Where xy represent page no. It can be 8 or 16 bit data, a register or a memory address.

Thus a mnemonic instruction is combination of an opcode and operand.

What do you mean by Architecture?

They play a critical role in users understanding of the logic behind the program. Push reset key. Enter Enter and store all the machine codes sequentially using hexadeciml key board on system. Reset the system.


Enter memory address where the programme begins and push execute key. Debugging the programme: It is nothing but finding the troubleshooting in a programme. Dehugging process can be divided into two parts, 1 Static debugging 2 Dynamic debugging Static debugging:Usually, each storage device holds one bit.

This is a simple single processor mode. Changing the combination of the address bits connected to the chip select changes the address range for the memory chip. Kennesaw State University offers undergraduateAs one of the Souths most innovative institutions in teaching and learning free electronic circuit designs graduate and doctoral degrees across two.

Then it will need 1 memory chip with 64 k locations, or 2 chips with 32 K in each, or 4 with 16 K each or 16 of the 4 K chips, etc.
