AVR CPU Core

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

Figure 3. 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 exe-

cuted, the next instruction 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.

The fast-access Register File contains 32 x 8-bit general purpose working registers with

a single clock cycle access time. This allows single-cycle Arithmetic Logic Unit (ALU)

operation. In a typical ALU operation, two operands are output from the Register File,
