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.

  • MOS Technology 6502
    MOS Technology 6502 Le MOS Technology 6502 est un microprocesseur 8 bits conçu par MOS Technology en 1975. Quand il fut présenté, il était de loin le processeur le plus économique sur le marché, à environ 1/6 du prix, concurrençant de plus grandes MOS Technology 6502 compagnies telles que Motorola ou Intel. Il était néanmoins plus rapide que la plupart d'entre eux, et avec le Zilog Z80, brilla dans une série de projets d'ordinateurs qui furent par la suite la source de la révolution d'ordinateurs personnels des années 1980. La production du 6502 était à l'origine concédée par MOS Technology à Rockwell et Synertek puis plus tard à d'autres compagnies ; il est encore fabriqué en 2014 pour équiper des systèmes embarqués. Sommaire 1 Histoire et utilisation 2 Description 3 Des caractéristiques floues 4 Remarques sur le 6502 5 Références 6 Liens externes (en français) Schema d'un circuit MOS 6502. 7 Liens externes (en anglais) Caractéristiques Production 1975 Histoire et utilisation Fabricant MOS Technology Fréquence 1 MHz à 1,55 MHz Le 6502 a été conçu principalement par l'équipe qui avait développé le Motorola 6800. Après avoir quitté Motorola en Finesse de 8000 nm à 8 000 nm bloc, ses ingénieurs ont rapidement sorti le 6501, d'une conception complètement nouvelle mais dont le brochage gravure restait néanmoins compatible avec le 6800. Motorola entama des poursuites judiciaires immédiatement, et bien qu'aujourd'hui l'affaire aurait été déboutée, les dommages que MOS encourut furent suffisants pour que la société Cœur MOS Tech 6502 accepte de cesser de produire le 6501.

    INTRODUCTION TO VLSI DESIGN WITH SYSTEM ON CHIP DESIGN REUSE: A TUTORIAL FOR STUDENTS by Frank J. Ventura Jr. An Applied Project in Partial Fulfillment of the Requirements for the Degree Master of Science in Technology ARIZONA STATE UNIVERSITY EAST March 2005 INTRODUCTION TO VLSI DESIGN WITH SYSTEM ON CHIP DESIGN REUSE: A TUTORIAL FOR STUDENTS by Frank J. Ventura Jr. has been approved March, 2005 APPROVED: ,Chair Dr. Narciso F. Macia Dr. Albert L. McHenry Dr. Don Cottrell Supervisory Committee ACCEPTED: Dr. Lakshmi V. Munukutla Department Chair ii ABSTRACT Due to the absence of a formal class in VLSI design at ASU East, the need arose for a hands-on tutorial that would introduce the students to VLSI design, emphasizing System-on-a-Chip design and the concept of design reuse. When UET 513 – Introduction to VLSI Design was taught at ASU East, The Western Design Center Inc. (WDC) supported this class by donating industry used software tools and their microprocessor Intellectual Property (IP) for the class to use in learning the concepts of VLSI Design. WDC continues to support the students at ASU East that are interested in VLSI design, by offering internships to give the students experience in the VLSI design flow. Students interested in using this tutorial will be able to work at WDC’s office and have access to the software tools and technology. The students will be following the design flow as used by WDC. The students will be exposed to the following design tools: ViewDraw for schematic entry, Silos for Verilog HDL simulation, ICED for laying out an IC, and PSPICE for electrical characterization.

I'm Steve Diamond, and we're doing in oral history of Bill Mensch. Thanks, Bill, for joining us. William David “Bill” Mensch: Well, thank you. Diamond: We'll be talking about a variety of subjects and your perceptions of what's happened in the past and, perhaps, where things are going in the future. Why don't we start out by talking about your youth and your education, and then we'll follow that up into your transition into the semiconductor world? Mensch: All right. Well, thanks for inviting me. It's an honor to be here right now, and I will enjoy telling you what I know about my life, how I got here. And we'll start, then, with my growing up on a farm in Pennsylvania, Bucks County, about 35 miles north of Philadelphia, very rural. The dairy farm had like 26 head of cattle, and I was a middle child of eight children I grew up with. And as a result, I got to explore because it was more fun being outside of the house rather than inside the house. When I was probably about 10 years old, we may have gotten a TV. We had a radio, liked to listen to the Lone Ranger.

Mensch Jr. has developed a rechargable battery powered computer. The Mensch Computer™ is based on the W65C265S, a 16-bit microcomputer which has a W65C816S as its core. The W65C816 is the CPU for the Apple Ilgs™, Super Nintendo™ and Digital Book System™ by Franklin Electronic Publishing. The W65C265S also has four serial ports to interface with a printer, keyboard, modem and PC. Two MenschCard (PCMCIA memory card) slots provide user memory upgrade for application software and data storage. The 240X128 LCD 40 column by 16 line monochrome display is ideal for telecommunications, directory, dictionary, digital books, control, game and hobby uses. The keyboard is full-sized for easy data entry. A Sega controller interface can be used for controlling applications and selecting from menus. This computer is also ideal for evaluating the W65C265S and W65C134S. The CPU module uses the W65C265S. The keyboard module uses the W65C134S as a low power keyboard controller, interfaced through the UART using it's low power CMOS interface.
