Please explain A64 architecture.

[HighwayAssassins]

Hey. Are A64s true x86 processors? And what is all the x86-64 business? Oh yea...and what the hell does x86 mean besides 386, 486 etc...

Google.com!

Anyway, I googed A64 Architecture x86 and look what popped up. Read this, and it will explain everything.

Also, I have a link to an image in my sig. I'm sure you'd appreciate the part about VIA

Here it is if you're too lazy to copy and paste. I know I almost am at this point.

I drew it myself

too lazy to copy and paste, but not too lazy to draw wtf lol.

You like that picture dont you? Yeah you do!

But the general idea is there.

This should explain it in sufficient detail

Those rendered hammers are freaking awesome! Thanks for the link.

x86 means exactly that.
once upon a time, intel released the 8086 processor, (along with the 8088 which only had an 8 bit address bus but that's not important), and IBM thought it was good. So they made a computer around it. And people thought the computer was good, so peopel made more.

This was the late seventies so the idea of an ISA (instruction set architecture) had taken root, that is multiple different CPUs woudl be built using the same instruction set, and software written for one of those CPUs would work on the all the rest.
The basic 8086 instruction set is still what we're saddled with today, the various chips in the line, intel took to naming 80x86, 'x' denoting the architectual generation. 286 was the second generation chip based on the 8086 ISA, 80368 the third ect ect ect. until now we have P4 which is the 7th generation 8086 chip.
Each generation of chip has extended the 8086 ISA to meet the needs of the day, but if you really wanted to get down and running some pure 8086 assembly code on your brand spanking new desktop, it would work.

If this doesnt explain it, then nothing will. literally. holy crap. pause... holy crap
