I am looking for a book explained how to make a computer by using Arm core processors?
Have you had a look at
Getting started with Arm Microcontroller Resources
If you really want to make your own thing then the mbed.org website might be a place to look at, for instance you'll find this nice little DIP there plus lots of other straightforward starter boards and software for microcontroller board development
