Can u explain instruction formats 8086 with example

I think U better explain exactly what it is YOU are asking.

I need instruction formats like one byte ,two byte etc... its explanations

You're still not being specific enough. Since this technology is over 30yrs old I am assuming it's for a class of some sort... am I right?

All of u asking various questions to me... but leaving my question unanswered... right..

We can't answer a question when we're unsure of what EXACTLY your question is...

What your asking for is the instruction code otherwise called the machine language code for a intel 8086. They haven't used those chips in a long time except now they use them in diagnostic tools and in cars to monitor the system.

Machine code - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Machine_code)


These chips became popular in the IBM personal computers when they first came out and the one following it was the 8088.

The rival chip at the time was the 6502. Comonly used in Atari 2600 video game consoles.

The first apples were based on that chip. (6502)

There are numerous sites on the Internet explaining Intel instruction sets and assembly language programming. Google is your friend.

Examples:
Wikipedia: x86 Instruction Listings (http://en.wikipedia.org/wiki/X86_instruction_listings)
The Intel 8086 / 8088/ 80186 / 80286 / 80386 / 80486 Instruction Set (http://home.comcast.net/~fbui/intel.html)
Complete 8086 instruction set (http://www.muslim-programers.com/1/inst.html)

Intel may still have their developer's manuals which included an instruction set reference on their web site, however I wasn't able to locate documentation for processors earlier than the 80386 but I didn't look very hard. The 8086 Family User's Manual (http://matthieu.benoit.free.fr/cross/data_sheets/8086_family_Users_Manual.pdf) may be of interest.
