MICROPROCESSOR To perform addition of two 8 bit numbers using 1) Start the program by loading HL register pair with address of memory . Enter the address location in which line program was executed. 4. Press “ Execute” key.

Write a program using Microprocessor for Decimal, Hexadecimal addition and subtraction of two Numbers. 2. Write a program using Microprocessor. Program 8: Binary to BCD conversion. Program 9: Addition of a series of numbers. 19 . The microprocessor was made by Intel in mid s. Microprocessor cannot understand a program written in Assembly language. • A program known as Assembler is used to convert a Assembly language program.
The starting addresses of array l, array2 and array3 are H, H and H, respectively. Statement: Write an assembly language program to separate even numbers from the given list of 50 numbers and store them in the another list starting from H.
Statement: Write assembly language program with proper comments for the following: A block of data consisting of bytes is stored in memory starting at H. This block is to be shifted relocated in memory from H onwards.
Do not shift the block or part of the block anywhere else in the memory. Therefore it is necessary to transfer last byte first and first byte last.
The length of the string is in memory location H and the string itself begins in memory location H. Place even parity in the most significant bit of each character.
The only 8-bit ALU operations that can have a destination other than the accumulator are the unary incrementation or decrementation instructions, which can operate on any 8-bit register or on memory addressed by HL, as for two-operand 8-bit operations. Direct copying is supported between any two 8-bit registers and between any 8-bit register and a HL-addressed memory cell, using the MOV instruction. An immediate value can also be moved into any of the foregoing destinations, using the MVI instruction.
Arrange in ascending order
Due to the regular encoding of the MOV instruction using nearly a quarter of the entire opcode space there are redundant codes to copy a register into itself MOV B,B, for instance , which are of little use, except for delays.
Adding HL to itself performs a bit arithmetical left shift with one instruction.
Adding the stack pointer to HL is useful for indexing variables in recursive stack frames. Subtraction and bitwise logical operations on 16 bits is done in 8-bit steps. Operations that have to be implemented by program code subroutine libraries include comparisons of signed integers as well as multiplication and division.
Undocumented instructions[ edit ] A number of undocumented instructions and flags were discovered by two software engineers, Wolfgang Dehnhardt and Villy M.
Sorensen in the process of developing an assembler.
These instructions use bit operands and include indirect loading and storing of a word, a subtraction, a shift, a rotate, and offset operations.
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. Find smallest of two 8-bit numbers Find largest from an array Find smallest from an array Binary to BCD conversion BCD to Binary conversion Sort the array in ascending order Sort the Array in descending order Factorial of 8 bit number Generate a fibonacci series Calculate the sum of series of numbers Multiplication of two bit numbers Division of two bit numbers Square wave generator Triangle wave generator Sawtooth wave generator Hopefully, this app will give a great help to the users.
Thank you for using this application.Some of them are followed by one or two bytes of data, which can be an immediate operand, a memory address, or a port number.
Get higher byte of the first number SBB H: Increment pointer2 INX B: Source program MVI E, Add two lower digits DAA: Get first operand INX H:
