hi i am new 2 microprocessors i wanna know how 2 design a microprocessor with programming and for special purposes...can any body help me with it.

 

Have you selected the microcontroller you would like to use?

I read your post as indicating that you want to literally design a special purpose microprocessor. Can you clear this up?

 

custom microprocessor? i would start out looking for a good cpu core
most people do that because a fully custom cpu can cost.. if you want to have one you design from scratch made.. CAD emulation/simulation software is the trick... but you need a fast computer to run sims of a fast cpu at full speed..

now if your talking about programming micro chips like mpu's and such atmel chips are easy to get started with you can make a programmer with just a few resistors

i'm not sure if i understand your question... hope this helps
