Introduction to X86 Assembly
CS342 Computer Security Handout # 5 Prof. Lyn Turbak Monday, Oct. 04, 2010 Wellesley College Lab 4: Introduction to x86 Assembly Reading: Hacking, 0x250, 0x270 Overview Today, we continue to cover low-level programming details that are essential for understanding software vulnerabilities like buffer overflow attacks and format string exploits. You will get exposure to the following: • Understanding conventions used by compiler to translate high-level programs to low-level assembly code (in our case, using Gnu C Compiler (gcc) to compile C programs). • The ability to read low-level assembly code (in our case, Intel x86). • Understanding how assembly code instructions are represented as machine code. • Being able to use gdb (the Gnu Debugger) to read the low-level code produced by gcc and understand its execution. In tutorials based on this handout, we will learn about all of the above in the context of some simple examples. Intel x86 Assembly Language Since Intel x86 processors are ubiquitous, it is helpful to know how to read assembly code for these processors. We will use the following terms: byte refers to 8-bit quantities; short word refers to 16-bit quantities; word refers to 32-bit quantities; and long word refers to 64-bit quantities. There are many registers, but we mostly care about the following: • EAX, EBX, ECX, EDX are 32-bit registers used for general storage. • ESI and EDI are 32-bit indexing registers that are sometimes used for general storage. • ESP is the 32-bit register for the stack pointer, which holds the address of the element currently at the top of the stack. -

CS 331 GDB and X86-64 Assembly Language
CS 331 Spring 2016 GDB and x86-64 Assembly Language I am not a big fan of debuggers for high-level languages. While they are undeniably useful at times, they are no substitute for careful coding. If code is well structured, I usually find it easier to debug analytically (i.e, by staring at it) than by running it through a debugger. In any event, monkey-coding with a debugger is still monkey-coding, and I don’t want to fly in an airplane being guided by monkey-code. The situation in assembly language is quite different. Assembly instructions can be opaque, especially if you aren’t used to programming in assembly language. In addition, I/O at the assembly level is quite complex; printing values at various places in your code is often not an option.. Debuggers are frequently the only way to discover what your code is actually doing. There are nicer assemblers than the gas (gnu assembler) that we will use, but the gas-gdb combination works quite well and is easy to use. In this document we’ll go briefly through the essential commands for gdb. There is more complete documentation available on any of the Linux systems; just type info gdb And, of course, there is no end of documentation online. To assemble your program with hooks for gdb use the hyphen g flag. For example, if your assembly language program is foobar.s you would assemble it wth gcc foobar.s –g –o foobar and then run gdp with gdb foobar You should always have the program visible in an editor that includes line numbers while you run gdb. -

To achieve this goal, analytical review of modern scientific-and-technical, normative, technical, and medical literature involving scientific and technical problems has been performed; the research area has been chosen and justified, including the definition of optimal electrodes and their affixing to the body of the patient, the definition of the best suitable power source and its operation mode, the definition of the best suitable useful signal amplifiers, and a system of filtering off external noises. A neuro-device mock-up has been made for recognizing electrophysiological signals and transmitting them to the exoskeleton, also the software has been written. -
Medidor Online De Temperatura Y Humedad De Bajo Consumo
Medidor online de temperatura y humedad de bajo consumo Estudiante: Jesús Santiago Fernández Prieto “Ingeniería Técnica de Informática de Sistemas” Consultor: Jordi Bécares Ferrés 11 de Junio de 2013 When I read commentary about suggestions for where C should go, I often think back and give thanks that it wasn't developed under the advice of a worldwide crowd. (D. Ritchie) A mi familia, novia y amigos. 2 Resumen Para este proyecto se ha diseñado un dispositivo con capacidad de conexión a Internet a través de un punto de acceso WIFI para el envío de datos y alertar en caso de posibles temperaturas y humedades críticas, definidas con un valor mínimo y un máximo. El diseño de este dispositivo se ha hecho teniendo en cuenta el reducir el consumo de energía para maximizar autonomía. El dispositivo está basado en una mota LPC1769 que posee un procesador Cortex-M3 de ARM el cual ejecuta nuestro programa desarrollado. Este programa hace uso del sistema operativo FreeRTOS (Free Real Time Operating System) que facilitará y nos asegurará estabilidad. La mota llevará conectada un chip WiFly que se usará para poder conectarnos por WiFi al punto de acceso. Cuenta además con un sensor SHT15 que permite, a la mota, tomar las mediciones de temperatura y humedad relativa. Estos serán posteriormente enviados al servidor. En caso de que en alguno de esos valores esté fuera del rango de seguridad se avisará al usuario a través de dos leds conectados también a la mota. Se le puede configurar una dirección de correo electrónico donde se enviarán alertas para enviar un correo al usuario advirtiéndole de un posible problema.
