Over View of Microprocessor 8085 and Its Application
IOSR Journal of Electronics and Communication Engineering (IOSR-JECE) e-ISSN: 2278-2834,p- ISSN: 2278-8735.Volume 10, Issue 6, Ver. II (Nov - Dec .2015), PP 09-14 www.iosrjournals.org Over view of Microprocessor 8085 and its application Kimasha Borah Assistant Professor, Centre for Computer Studies Centre for Computer Studies, Dibrugarh University, Dibrugarh, Assam, India Abstract: Microprocessor is a program controlled semiconductor device (IC), which fetches, decode and executes instructions. It is versatile in application and is flexible to some extent. Nowadays, modern microprocessors can perform extremely sophisticated operations in areas such as meteorology, aviation, nuclear physics and engineering, and take up much less space as well as delivering superior performance Here is a brief review of microprocessor and its various application Key words: Semi Conductor, Integrated Circuits, CPU, NMOS ,PMOS, VLSI I. Introduction: Microprocessor is derived from two words micro and processor. Micro means small, tiny and processor means which processes something. It is a single Very Large Scale of Integration (VLSI) chip that incorporates all functions of central processing unit (CPU) fabricated on a single Integrated Circuits (ICs) (1).Some other units like caches, pipelining, floating point processing arithmetic and superscaling units are additionally present in the microprocessor and that results in increasing speed of operation.8085,8086,8088 are some examples of microprocessors(2). The technology used for microprocessor is N type metal oxide semiconductor(NMOS)(3). Basic operations of microprocessor are fetching instructions from memory ,decoding and executing them ie it takes data or operand from input device, perform arithmetic and logical operations and store results in required location or send result to output devices(1).Word size identifies the microprocessor.E.g. -

D-2 I Appendix D An Alternative to RISC: The Intel 80x86 D.1 Introduction MIPS was the vision of a single architect. The pieces of this architecture fit nicely together and the whole architecture can be described succinctly. Such is not the case of the 80x86: It is the product of several independent groups who evolved the architecture over 20 years, adding new features to the original instruction set as you might add clothing to a packed bag. Here are important 80x86 milestones: I 1978—The Intel 8086 architecture was announced as an assembly language– compatible extension of the then-successful Intel 8080, an 8-bit microproces- sor. The 8086 is a 16-bit architecture, with all internal registers 16 bits wide. Whereas the 8080 was a straightforward accumulator machine, the 8086 extended the architecture with additional registers. Because nearly every reg- ister has a dedicated use, the 8086 falls somewhere between an accumulator machine and a general-purpose register machine, and can fairly be called an extended accumulator machine. -

INTRODUCTION 1. Despite Intel’s intentional concealment of specific design choices that it long knew rendered its central processing units (“CPUs” or “processors”) unsecure, it was only in January 2018 that it was first revealed to the public that Intel’s CPUs have significant security vulnerabilities that gave unauthorized program instructions access to protected data. 2. A CPU is the “brain” in every computer and mobile device and processes all of the essential applications, including the handling of confidential information such as passwords and encryption keys. -

Schueckler Professor _~~ _ Professor __~__:--:~-=- _ (Department Head) DEPARTMENT OF ELECTRICAL ENGINEERING COLLEGE OF ENGINEERING ROCHESTER INSTITUTE OF TECHNOLOGY ROCHESTER, NEW YORK MAY, 1988 Abstract This project was originally suggested by J. Schueckler as an aid to teaching students the Intel 8086 Assembly Language. The need for such a tool becomes apparent when one considers the expense of providing students with dedicated hardware that rapidly becomes obsolete, but a Simulator which could be easily updated and runs on a general purpose or timesharing computer system would be accessible to many students for a fraction of the cost. The intended use of the Simulator therefore dictated that it precisely model the hardware, be available on a multiuser system and run as efficiently as possible. -

Programmable Digital Microcircuits - a Survey with Examples of Use
- 237 - PROGRAMMABLE DIGITAL MICROCIRCUITS - A SURVEY WITH EXAMPLES OF USE C. Verkerk CERN, Geneva, Switzerland 1. Introduction For most readers the title of these lecture notes will evoke microprocessors. The fixed instruction set microprocessors are however not the only programmable digital mi• crocircuits and, although a number of pages will be dedicated to them, the aim of these notes is also to draw attention to other useful microcircuits. A complete survey of programmable circuits would fill several books and a selection had therefore to be made. The choice has rather been to treat a variety of devices than to give an in- depth treatment of a particular circuit. The selected devices have all found useful ap• plications in high-energy physics, or hold promise for future use. The microprocessor is very young : just over eleven years. An advertisement, an• nouncing a new era of integrated electronics, and which appeared in the November 15, 1971 issue of Electronics News, is generally considered its birth-certificate. The adver• tisement was for the Intel 4004 and its three support chips. The history leading to this announcement merits to be recalled. Intel, then a very young company, was working on the design of a chip-set for a high-performance calculator, for and in collaboration with a Japanese firm, Busicom. One of the Intel engineers found the Busicom design of 9 different chips too complicated and tried to find a more general and programmable solu• tion. His design, the 4004 microprocessor, was finally adapted by Busicom, and after further négociation, Intel acquired marketing rights for its new invention. -

From: [email protected] (J. Bayko) Date: 12 Jun 92 18:49:18 GMT Newsgroups: alt.folklore.computers,comp.arch Subject: Great Microprocessors of the Past and Present I had planned to submit an updated version of the Great Microprocessor list after I’d completed adding new processors, checked out little bits, and so on... That was going to take a while... But then I got to thinking of all the people stuck with the origional error-riddled version. All these poor people who’d kept it, or perhaps placed in in an FTP site, or even - using it for reference??! In good conscience, I decided I can’t leave that erratic old version lying out there, where people might think it’s accurate. So here is an interim release. There will be more to it later - the 320xx will be included eventually, for example. But at least this has been debugged greatly. Enjoy... John Bayko. — Great Microprocessors of the Past and Present (V 3.2.1) Section One: Before the Great Dark Cloud. ————————— Part I: The Intel 4004 (1972) The first single chip CPU was the Intel 4004, a 4-bit processor meant for a calculator. It processed data in 4 bits, but its instructions were 8 bits long. Internally, it featured four 12 bit(?) registers which acted as an internal evaluation stack. The Stack Pointer pointed to one of these registers, not a memory location (only CALL and RET instructions operated on the Stack Pointer). There were also sixteen 4-bit (or eight 8-bit) general purpose registers The 4004 had 46 instructions. -
Computer Architecture Lecture 1: Introduction and Basics Where We Are
Computer Architecture Lecture 1: Introduction and Basics Where we are “C” as a model of computation Programming Programmer’s view of a computer system works How does an assembly program end up executing as Architect/microarchitect’s view: digital logic? How to design a computer that meets system design goals. What happens in-between? Choices critically affect both How is a computer designed the SW programmer and using logic gates and wires the HW designer to satisfy specific goals? HW designer’s view of a computer system works CO Digital logic as a model of computation 2 Levels of Transformation “The purpose of computing is insight” (Richard Hamming) We gain and generate insight by solving problems How do we ensure problems are solved by electrons? Problem Algorithm Program/Language Runtime System (VM, OS, MM) ISA (Architecture) Microarchitecture Logic Circuits Electrons 3 The Power of Abstraction Levels of transformation create abstractions Abstraction: A higher level only needs to know about the interface to the lower level, not how the lower level is implemented E.g., high-level language programmer does not really need to know what the ISA is and how a computer executes instructions Abstraction improves productivity No need to worry about decisions made in underlying levels E.g., programming in Java vs. C vs. assembly vs. binary vs. by specifying control signals of each transistor every cycle Then, why would you want to know what goes on underneath or above? 4 Crossing the Abstraction Layers As long as everything goes well, not knowing what happens in the underlying level (or above) is not a problem. -
