The Basics of Intel® Architecture

Executive Summary
Intel® architecture is a powerful computing architecture that utilizes some fundamental ingredients for specific functions. The basic workings of these ingredients may not be intuitive to those who have never designed with Intel® architecture in the past.
The goal of this paper is to describe the basic operation and function to the platform for the ingredients used in three classes of Intel® architecture platforms. The paper will focus on the platforms featuring the Intel® Atom™ processor, the Intel® Core™ 2 Duo processor, and the Intel® Core™ i7 processor.
The paper will walk through the operation of a processing core’s communication with memory and I/O, the path of interaction between different types of I/O and memory, and a high level description of how the CPU gets and utilizes data. The various system components are described along with the services they provide. A brief introduction to critical support components (clocks, voltage regulators, super I/O) is given.
This paper will also provide an explanation for the common terms used when describing Intel® architecture designs and operation. The final section shall highlight the design aids and collateral that Intel provides customers to help them create successful products.
