8086 microprocessor instruction set with example

8086 Microprocessor Assembly Comparison Example The code below compares two numbers and print if number 1 is equal, greater or less than number 2. This code is implemented using three conditional branches which are JE, JB and JA. Assembly Code JA/JNBE will check the CF and ZF flags. If both are 0, then the IP will jump to the target address. inside their computer. 8086 microprocessor instruction set with example is welcoming in our digital library an online permission to it is set as public consequently you can download it instantly. Our digital library saves in combination countries, allowing you to get the most less latency times to download any of our books once this one. 8086 INSTRUCTION SET DATA TRANSFER INSTRUCTIONS 8086 will generate a type 0 interrupt. All flags are undefined after a DIV instruction. If you want to divide a byte by a byte, you must first put the dividend byte in AL and fill AH with all 0's. Likewise, if you want to divide a word by another word, then put the dividend word in AX and In this article, we are going to discuss about the 6 general formats of instructions. One byte instruction: This is only one byte long and may have implied data and register. Register to register: This instruction is 2 byte long. First byte specified opcode and width (w) of opcode and second byte specified register operand and R/M field. Instruction Set of 8085 Microprocessor & Its Classification. The first commercially successful microprocessor is the 8085 microprocessor by Intel. This microprocessor was mainly developed to eliminate the drawbacks of 8080 architecture. 8085 microprocessor is an 8-bit microprocessor because at a time it works on 8-bits and the technology used 8086 AND logical Instruction The AND instruction is 8086 microcontroller is performs bit by bit logical AND operation of two operands and places the result in the specified destination. Example - Assembly Language Program MOV AL, 10101110b AND AL, 11110110b ; result in AL=10100110b = A6h Emulator Result 8086 OR Logical Instruction The 8086 Microprocessor Kit is a single board computer designed for self-learning the 16-bit microprocessor operations. The CPU is 8086 with 16-bit memory interface. The monitor ROM provides functions for entering 8086 instruction code using onboard hex key, testing code running, single stepping and display user registers. 1. INSTRUCTION SET OF 8086 MICRPOROCESSOR. 2. CATEGORIES The instruction set are categorized into the following types: Data transfer instructions Arithmetic instructions Logical instructions Flag manipulation instructions shift and rotate instructions String instructions 8086 assembler directives. 3. Instruction to transfer a word. MOV − Used to copy the byte or word from the given source to the given destination.; PPUSH − Used to put a word at the top of the stack.; POP - helps in getting a word from the top of the stack to the given location.; PUSHA − Used to keep all the registers into the stack.; POPA − Used to get words from the stack to all registers. Microprocessor Microcontroller 8086 These instructions are used to perform operations where data bits are involved, i.e. operations like logical, shift, etc. We can say that these instructions are logical instructions. In 8086, the destination register may or may not the Accumulator. Let us see the logical instructions of 8086 microprocessor. The 8086 m
