Embedded Systems: An Integrated Approach by Pearson

Introduction

In this book, many processors have been discussed; all of them are designated as embedded

processors/microcontrollers.  e key features of these processors are that of having a

CPU and a number of peripherals.  e ‘computing power’ of the chip depends on the

CPU core that is present. For instance, MCUs with an ARM core are more powerful

than those with an 8051 core.  ese kinds of processor cores are referred to as ‘general

purpose’ cores, because they are good at ordinary, that is, general purpose arithmetic and

data processing.

But for specialized arithmetic operations like fast multiply and add, fl oating point

arithmetic, exponentiation, ...
