The Myth of the Innovator Hero - Business - the Atlantic

Print | Close By Vaclav Smil Every successful modern e-gadget is a combination of components made by many makers. The story of how the transistor became the building block of modern machines explains why. WIKIPEDIA: Steve Jobs, Thomas Edison, Benjamin Franklin We like to think that invention comes as a flash of insight, the equivalent of that sudden Archimedean displacement of bath water that occasioned one of the most famous Greek interjections, εὕρηκα. Then the inventor gets to rapidly translating a stunning discovery into a new product. Its mass appeal soon transforms the world, proving once again the power of a single, simple idea. But this story is a myth. The popular heroic narrative has almost nothing to do with the way modern invention (conceptual creation of a new product or process, sometimes accompanied by a prototypical design) and innovation (large-scale diffusion of commercially viable inventions) work. A closer examination reveals that many award-winning inventions are re-inventions. Most scientific or engineering discoveries would never become successful products without contributions from other scientists or engineers. Every major invention is the child of far-flung parents who may never meet. These contributions may be just as important as the original insight, but they will 1 of 4 11/20/2011 8:48 PM The Myth of the Innovator Hero - Business - The Atlantic http://www.theatlantic.com/business/print/2011/11/the-myth-of-the-inno... not attract public adulation. -

541 COMPUTER ENGINEERING Niyazgeldiyev M. I., Sahedov E. D
COMPUTER ENGINEERING Niyazgeldiyev M. I., Sahedov E. D. Turkmen State Institute of Architecture and Construction Computer engineering is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software. Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware–software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture. Usual tasks involving computer engineers include writing software and firmware for embedded microcontrollers, designing chips, designing analog sensors, designing mixed signal, and designing operating systems. Computer engineers are also suited for research, which relies heavily on using digital systems to control and monitor electrical systems like motors, communications, and sensors. In many institutions of higher learning, computer engineering students are allowed to choose areas of in–depth study in their junior and senior year because the full breadth of knowledge used in the design and application of computers is beyond the scope of an undergraduate degree. Other institutions may require engineering students to complete one or two years of general engineering before declaring computer engineering as their primary focus. Computer engineering began in 1939 when John Vincent Atanasoff and Clifford Berry began developing the world's first electronic digital computer through physics, mathematics, and electrical engineering. John Vincent Atanasoff was once a physics and mathematics teacher for Iowa State University and Clifford Berry a former graduate under electrical engineering and physics. -

This development has enabled us to store hundreds of thousands of transistors into one chip. That was a precondition for the manufacture of microprocessors. The first computers were made by adding external peripherals such as memory, input/output lines, timers and others to it. Further increasing of package density resulted in creating an integrated circuit which contained both processor and peripherals. That is how the first chip containing a microcomputer later known as a microcontroller has developed. This is how it all got started... In the year 1969, a team of Japanese engineers from BUSICOM came to the USA with a request that a few integrated circuits for calculators were to be designed according to their projects. The request was sent to INTEL and Marcian Hoff was in charge of the project there. Having experience working with a computer, the PDP8, he came up with an idea to suggest fundamentally different solutions instead of the suggested design. This solution presumed that the operation of integrated circuit was to be determined by the program stored in the circuit itself. It meant that configuration would be simpler, but it would require far more memory than the project proposed by Japanese engineers. -
Microprocessor (Edited from Wikipedia)
Microprocessor (Edited from Wikipedia) SUMMARY A microprocessor is a computer processor which incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, clock-driven [crystal oscillator-driven], register based, digital-integrated circuit which accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary numeral system. Combinational logic is a type of digital logic which is implemented by Boolean [true or false] circuits, where the output is a pure function of the present input only. This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input. In other words, sequential logic has memory while combinational logic does not. The integration of a whole CPU onto a single chip or on a few chips greatly reduced the cost of processing power, increasing efficiency. Integrated circuit processors are produced in large numbers by highly automated processes resulting in a low per unit cost. Single-chip processors increase reliability as there are many fewer electrical connections to fail. As microprocessor designs get better, the cost of manufacturing a chip (with smaller components built on a semiconductor chip the same size) generally stays the same. Before microprocessors, small computers had been built using racks of circuit boards with many medium- and small-scale integrated circuits. -

Amer Iqbal Qureshi M icrotronics Pakistan Teach Yourself PIC Microcontrollers | www.electronicspk.com | 2 About This Book This book, is an entry level text for those who want to explore the wonderful world of microcontrollers. Electronics has always fascinated me, ever since I was a child, making small crystal radio was the best pro- ject I still remember. I still enjoy the feel when I first heard my radio. Over the period of years and decades electronics has progressed, analogs changed into digital and digital into programmable. A few years back it was a haunting task to design a project, solely with gates and relays etc, today its ex- tremely easy, just replace the components with your program, and that is it. As an hobbyist I found it extremely difficult, to start microcontrollers, however thanks to internet, and ex- cellent cataloging by Google which made my task easier. A large number of material in this text has its origins in someone else’s work, like I made extensive use of text available from Mikroelectronica and other sites. This text is basically an accompanying tutorial for our PIC-Lab-II training board. I wish my this attempt help someone, write another text.

How Microprocessors Were Born
WHAT IS A MICROPROCESSOR A microprocessor is an electronic component that is used by a computer to do its work. It is a central processing unit on a single integrated circuit chip containing millions of very small components that work together. Since the first microprocessor To the latest microprocessor 1970s 2019s The Intel4004 is considered the first microprocessor, its creation by Intel came down to a combination of hard work, the right timing and just plain luck. The plain of the chip begins in 1969 when the Busicom conrtracted wit Intel to buil a chips needed for a new calculator. It operated on 4 bit and it was ideated by Federico Faggin e Marcian Hoff 8(also called Ted Hoff). Intel 4004 Federico Faggin Marcian Hoff THE APPLE A13 The Apple A13 Bionic is a 64-bit ARM-based system on a chip, designed by Apple Inc. It appears in the IPhone 11 and Iphone 11 Pro. The Apple A13 Bionic features an Apple-designed 64-bit ARMv8.3-A six-core CPU, with two high-performance cores running at 2.65 GHz called Lightning and four energy- efficient cores called Thunder. The Lightning cores feature machine learning accelerators called AMX blocks. Apple claims the AMX blocks are six times faster at matrix multiplication than the Apple A12's Vortex cores. The AMX blocks are capable of up to one trillion 8-bit operations per second.
