AVR CPU Core

5.1

Introduction

This section discusses the AVR core architecture in general. The main function of the CPU core

is to ensure correct program execution. The CPU must therefore be able to access memories,

perform calculations, control peripherals, and handle interrupts.

Architectural Overview

Block Diagram of the AVR Architecture

In order to maximize performance and parallelism, the AVR uses a Harvard architecture – with

separate memories and buses for program and data. Instructions in the Program memory are

executed with a single level pipelining. While one instruction is being executed, the next instruc-

tion is pre-fetched from the Program memory. This concept enables instructions to be executed

in every clock cycle. The Program memory is In-System Reprogrammable Flash memory.
