Introducción a la Organización del Ordenador Usando Ensamblador con un Raspberry Pi

Subsistema del Ordenador

*Subsistema del Ordenador*

[Introduction to Computer OrganizationARM Assembly Language Using the Raspberry Pi] (http://bob.cs.sonoma.edu/IntroCompOrg-RPi/frontmatter-1.html) es un libro electrónico y gratuito que nos enseña cómo funciona el hardware, a bajo nivel, de un ordenador desde el punto de vista del programador.

Para ello, se basa en uno de nuestros “juguetes” favoritos: Raspberry Pi, con Raspbian y usando lenguaje ensamblador para la arquitectura de la CPU de dicho dispositivo: ARM.

El objetivo del libro es que el lector llegue a entender como funciona un ordenador desde el nivel más bajo. Aunque uno prácticamente no escriba aplicaciones directamente en ensamblador, sin duda alguna te hará mucho mejor a la hora de programar, analizar malware, realizar ingeniería inversa, etc.

El libro empieza desde los conceptos más básicos como la preparación de tu Raspberry Pi o el sistema binario, hasta el uso de interrupciones y el GPIO.

El índice del mismo es el siguiente:
