Microprocessors have become a part of our daily lives and it would be difficult to imagine life without them today. From digital wrist watches, to pocket calculators, from microwaves, to cars, toys, security systems, navigation, to credit cards, microprocessors are ubiquitous. All this has been made possible by remarkable developments in semiconductor technology enabling in the last 30 years, enabling the implementation of ideas that were previously beyond the average computer architect’s grasp. In this paper, we discuss the various microprocessor technologies, starting with a brief history of computing. This is followed by an in-depth look at processor architecture, design philosophies, current design trends, RISC processors and CISC processors. Finally we discuss trends and directions in microprocessor design. Brief Historical Overview Mechanical Computers A French engineer by the name of Blaise Pascal built the first working mechanical computer. This device was made completely from gears and was operated using hand cranks. This machine was capable of simple addition and subtraction, but a few years later, a German mathematician by the name of Leibniz made a similar machine that could multiply and divide as well. After about 150 years, a mathematician at Cambridge, Charles Babbage made his Difference Engine.

ISAs include accumulator architectures, general-purpose register architectures, stack architectures, and a brief history of ARMv7 and the x86. We also review the controversial subjects of high-level-language computer architectures and reduced instruction set computer architectures. Th e history of programming languages includes Fortran, Lisp, Algol, C, Cobol, Pascal, Simula, Smalltalk, C+ + , and Java, and the history of compilers includes the key milestones and the pioneers who achieved them. Accumulator Architectures Hardware was precious in the earliest stored-program computers. Consequently, computer pioneers could not aff ord the number of registers found in today’s architectures. In fact, these architectures had a single register for arithmetic instructions. Since all operations would accumulate in one register, it was called the accumulator , and this style of instruction set is given the same name. For example, accumulator Archaic EDSAC in 1949 had a single accumulator. term for register. On-line Th e three-operand format of RISC-V suggests that a single register is at least two use of it as a synonym for registers shy of our needs.

  • Hardware Goal: a Motorola 6809 Processor Running on a Board
    MC6809/6502 ATX/6U Computer aka COLOSSUS Hardware Goal: A Motorola 6809 processor running on a board which will mount in an ATX case or in a 6U card cage. Board dimensions are 160mm x 233.35mm (6.3” x 9.2”). A Propellor subsystem provides a VGA terminal and PS/2[?] keyboard interface. Timer, parallel ports, and a separate serial port are included. The design is based on the original “6x0x” board which operates as an ECB peripheral. A second CPU socket will be provided for either a 6502 or 6802 CPU chip. This chip may be installed and operated if the 6809 is removed. Software Goal: It looks like NitrOS9 level 2 is the most powerful s/w we could bring up on this board; but a paged MMU is required. This software goal is now driving the hardware design effort. Design Strategy: Recently the project was divided into smaller, more manageable pieces. A master schematic sheet now indexes close to a dozen independent subsystems. If individual subsystems can be handled by persons with expertise in a particular area, this will save passing around one huge schematic. Integration of an update to one subsystem which does not affect other parts of the system will be as simple as replacing one subsystem schematic with an updated version. Kicad facilitates this with the “schematic hierarchy,” and this looks to ease some of the integration headaches. Technical Stuff CPU-1: The design is for a 2Mhz MC68B09 chip. Note this is not the 6809E. The -E suffix chip is electrically different.

  • Bringing Back the VOICE of Speak & Spell
    Bringing Back THE VOICE of Speak & Spell Created by Phillip Burgess Last updated on 2019-10-25 07:00:23 AM UTC Overview This project makes an Adafruit Trellis M4 faithfully replicate the voice of Speak & Spell. The Texas Instruments Speak & Spell and its descendants were electronic educational toys sold from the late 1970s into the early 1990s. If you were around for it, chances are you know that voice, even if you don’t recall the spelling games that went with it. © Adafruit Industries https://learn.adafruit.com/bringing-back-the-voice-of-speak-spell Page 3 of 11 Like any of our senses, sound can summon strong nostalgic feelings. The Yamaha DX7 synthesizer left its fingerprints all over 1980s pop music. Chiptune aficionados will insist that analog peculiarities of a real Commodore 64’s SID chip can never be perfectly emulated in software. Stephen Hawking was so known for his specific accent that he kept (or emulated) it even as better-sounding technology came along. © Adafruit Industries https://learn.adafruit.com/bringing-back-the-voice-of-speak-spell Page 4 of 11 And so it goes with early speech synthesis technology. A Votrax SC-01 (used in MicroVox and Heathkit HERO 1) was distinct from S.A.M. (Software Automatic Mouth) was distinct from the General Instrument SPO256 IC (which could be had from Radio Shack) and so forth. Each has its own peculiar flavour. I can’t explain why I wanted to bring back the Speak & Spell voice specifically. I just…did. It’s that nostalgia thing, and anybody who knows and hears it will laugh.

  • Microprocessors: from Basic Chips to Complete Systems
    - 237 - MICROPROCESSORS: FROM BASIC CHIPS TO COMPLETE SYSTEMS R. W. Dobinson,*) University of Illinois, Urbana, Illinois, USA. "Good-morning, good morning!", the General said When we met him last week on our way to the line. Now the soldiers he smiled at are most of them dead, And we're cursing his staff for Incompetent swine. "He's a cheery old card," grunted Harry to Jack As they slogged up to Arras with rifle and pack. * * * * But he did for them both by his plan of attack. Siegfried Sassoon April 1917 1. AIMS OF THESE LECTURES Microprocessor technology has, since its conception and birth in the early 1970's, entered very many areas of our lives. No end to its growth is in sight, and new uses appear almost daily. The semiconductor industry continues to produce ever more powerful integrated circuits (known far and wide as chips); more functionality and speed at lower cost is every salesman's cry. These lectures aim to present and explain in general terms some of the characteristics of microprocessor chips and associated components. They will show how systems are synthesized from the basic integrated circuit building blocks which are currently available; processor, memory, input-output (I/O) devices, etc. It is not my intention to discuss in detail the many different microprocessors now available on the market, nor will a complete catalogue of support chips be presented. Time will not permit this. Instead, emphasis will be placed on explaining the basic principles of different types of chip. As far as possible X will avoid talking too much about any specific devices; thus I will spend some time discussing a generic microprocessor accessing generic memory and talking to the outside world via generic I/O devices.
