A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements.

  • Sistema Operativo
    Sistema Operativo L.I. Francisco Ruiz Sala Instituto de Astronomía UNAM Definición: Un Sistema Operativo del acrónimo en ingles OS (Operating System) es un programa o programas que gestiona los recursos de hardware y provee servicios y las aplicaciones, una herramientas de software que permiten la interacción con el núcleo o Kernel (Nucleo) y este es el encargado de enviar e interpretar las instrucciones en código de máquina. Evolución histórica 1ª Generación (1945 -1955) Estas máquinas estaban construidas por medio de tubos de vacío. Eran programadas en lenguaje de máquina. 2ª Generación (1955 – 1965) Las características de la segunda generación son las siguientes: Están construidas con circuitos de transistores. Se programan en nuevos lenguajes nemotécnicos como el Ensamblador. 3ª Generación (1965 – 1975) Las características de esta generación fueron las siguientes: Su fabricación electrónica está basada en circuitos integrados. Su manejo es por medio de los lenguajes de control de los sistemas operativos, Lenguajes de Alto Nivel. 4ª Generación (1975 – 1990) Aquí aparecen los microprocesadores que es un gran adelanto de la microelectrónica, son circuitos integrados de alta densidad y con una velocidad impresionante. Las microcomputadoras con base en estos circuitos son extremadamente pequeñas y baratas, por lo que su uso se extiende al mercado industrial. Aquí nacen las computadoras personales, Lenguajes Interpretes y de Alto nivel. Tipos de SO: -Monoprocesos, Multiprocesos, Monousuarios y multiusuarios Kernel: El núcleo o Kernel (de la raíz germánica Kern, núcleo, hueso) es la parte fundamental del sistema operativo, y se define como la parte que se ejecuta en modo privilegiado (conocido también como modo núcleo).

  • ARM Architecture from Wikipedia, the Free Encyclopedia
    ARM architecture From Wikipedia, the free encyclopedia ARM is a family of instruction set architectures for computer ARM architectures processors based on a reduced instruction set computing (RISC) architecture developed by British company ARM Holdings. A RISC-based computer design approach means ARM The ARM logo processors require significantly fewer transistors than typical Designer ARM Holdings CISC x86 processors in most personal computers. This approach reduces costs, heat and power use. These are Bits 32-bit, 64-bit ​ desirable traits for light, portable, battery-powered devices— Introduced 1985 including smartphones, laptops, tablet and notepad computers, and other embedded systems. A simpler design Design RISC facilitates more efficient multi-core CPUs and higher core Type Register-Register counts at lower cost, providing improved energy efficiency Branching Condition code for servers.[3][4][5] Open Proprietary ARM Holdings develops the instruction set and architecture for ARM-based products, but does not manufacture 64/32-bit architecture products. The company periodically releases updates to its Introduced 2011 cores. Current cores from ARM Holdings support a 32-bit address space and 32-bit arithmetic; the ARMv8-A Version ARMv8-A architecture, announced in October 2011,[6] adds support Encoding AArch64/A64 and AArch32/A32 use for a 64-bit address space and 64-bit arithmetic. Instructions 32-bit instructions, T32 (Thumb2) for ARM Holdings' cores have 32-bit-wide fixed-length uses mixed 16- and 32-bit instructions. instructions, but later versions of the architecture also support ARMv7 user-space compatibility[1] a variable-length instruction set that provides both 32-bit and 16-bit-wide instructions for improved code density.
