Paperback. Condition: new. Paperback. Rich in very diverse railroad history CSX Transportation (CSXT) is the largest eastern railroad and also one of the safest in the country. CSXT is the end result of over 150 years of railroad evolution in the United States. The largest part of CSXT consists of elements of the Chessie System and the Seaboard Coast Lines. Dozens of "fallen flag" lines such as the Baltimore & Ohio, Chesapeake & Ohio, Western Maryland, Atlantic Coast Line, Richmond, Fredericksburg, and Potomac, Family Line, s and many more make up the modern CSXT.CSXT's rail spans the United States east of the Mississippi exclusive of New England. The northern portion, the Chessie system heritage serves the industrial northeast and the coal fields of Maryland, West Virginia, Pennsylvania and Kentucky. The southern section, from the SCL, handles minerals, chemicals and ocean ports. The building blocks of CSXT are the history, roadbed, and hard work of hundreds of predecessor roads, from the very beginning of flanged wheel on iron rail in America.From a 50 year old SW1200 workhorse switching cars in a yard, to mile-long unit coal trains headed by 15,000 horsepower of modern AC traction, CSXT never sleeps. CSXT uses locomotives from major United State's manufacturers General Electric (GE) and Electromotive Division (EMD), as well as new-comer NRE. The CSXT fleet of locomotives at the end of 2018 numbered around 4,000 locomotives.As this book was being prepared, CSX has 3873 units on its roster, with 800 being stored. That gives some 13,225,000 raw horsepower available. This is a data book, not a color picture book, to keep costs down. There are numerous websites and books with nice color pictures of CSX locomotives mentioned in the Reference and Resources sections. Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.

It is somewhat architecture-neutral, but does restrict the discussion to binary computation in digital computers based on software and microelectronics technology. To understand why we need the complexity of floating point for scientific, engineering, and financial calculations, we need to review number systems, integer calculations in binary and decimal, and other representations systems, as well as the concept of negative numbers and zero. This work contains a broad list of floating point units and software packages.Both software and hardware approaches are discussed for 8-bit to 64-bit integer machines. The IEEE standard for floating point is discussed, as well as the previous mainframe era standards. A glossary and list of references are included.

By the 1990's, it was becoming increasingly obvious that Massively Parallel Microprocessor-based Systems (MPMS) were becoming significant new forces in the marketplace. It is important to realize that in a rapidly moving, trendy area such as MPMS, by the time information is published, it is probably obsolete. By the time a book is published, it is probably only of historical significance. This book is intended for the hardware or software practitioner to use as an introduction to the subject. It assumes that the reader know something about the internals of computer systems, architecture, and instruction execution. It would be relevant for an advanced undergraduate or graduate level course in computer design or architecture. It discusses the chip level of MPMS, and looks at the design trade-offs at the systems level. This document covers the field of MPMS. This is a subset of the field of Massively Parallel Computers. Although this variety of computer has been around for a long time, it only started to make an impact on the computer industry in the 1990's, as an alternative to supercomputers. The goal of this document is to give the reader an introductory look at the fundamentals of MPMS design, to allow the reader to understand the trade-offs, limitations, speed, cost, complexity, and architectures. The reader will be shown the history and the trends of the technology of this rapidly moving field. To achieve these goals, we'll review the basics and background of the technology, to understand where the trade-offs are. We'll then look at real-world design examples to see how the trade-offs were made. It is essential to realize that in MPMS technology, as in many cutting edge endeavors, there are no wrong answers in the marketplace, but a multitude of right ones. The wrong answers either never make it to the market, or don't last long there.

This book surveys the history and architecture of 8-bit microprocessors. We actually start with 4-bit microprocessors, look at a strange 1-bit processor, and look at 8-bit, then 12 bit micros. The 16-bit processors will be the subject of another book. Eight bit processors are still manufactured and used. This book is not an exhaustive view of the field, but the major players are covered. There is a review of computer architecture, binary math, and digital logic that can be skipped. The evolution of the 8-bit processors is a history of the advance of semiconductor technology from the first transistors, to the breakthrough of multiple transistors on a chip, the integrated circuit. A lot of this happened when the "Silicon Valley" of northern California was mostly known for its citrus crops. The tools that made all this happen were large mainframe computers with vacuum tube technology, punched card input, and memory drums with the staggering capacity of a thousand words. The growth of the integrated circuit shows what Gordon Moore observed was an exponential growth law: the complexity increased about every 18 months. Naturally, this growth rate is not sustainable forever. But, in the age of multi-core 64 bit microprocessor systems on a chip, so far, so good.Modern computers started out using relays and vacuum tubes, switching to mechanical relays for switching elements. The semiconductor revolution provided diodes for logic functions, and transistors for switching. As the technology allowed for putting multiple transistors and other elements on a single substrate, the integrated circuit began to be widely used. The complexity of the devices increased according to an exponential growth law, the technology feeding upon itself. This allowed for functions such as an arithmetic-logic unit to occupy one chip. Then, at around 4,000 transistors capacity, an entire 4-bit cpu that executed instructions. Not much later came the 8-bit cpu. Memory and I/O functions also benefited from the increasingly complex solid state-electronics.glossary, bibliography, and pictures are included.The author built an Intel 8080-based Altair 8800 computer in 1975. He went to the Big Computer Faire in Atlantic City, and saw two guys, both named Steve, from California, with a wooden-cased project that probably wasn't going to go anywhere commercially. His Aerospace career has revolved around support for space-based microprocessors and computers for NASA since 1971.Mr. Stakem received a Bachelor's Degree in Electrical Engineering from Carnegie Mellon University, and masters in Physics and Computer Science from the Johns Hopkins University. He has followed a career as a NASA support contractor, working at every NASA Site. He is associated with the Graduate Computer Science Department at Loyola University in Maryland, and the Whiting School of Engineering of the Johns Hopkins UniversityAnother book by the author discusses 16-bit microporcessors.

The Transputer was a microprocessor too far ahead of its time. Update the clock speeds, and the architecture would be impressive today. It was a actually a microcomputer, having a cpu, memory, and I/O on one chip. External logic required was minimal. Large arrays of Transputers were easily implemented. However, like many advanced technological artifacts, it was hard to understand. It took a while to get used to the software approach. The tools were difficult to use. In fact, the software approach, the conceptual model, was what made the Transputer powerful. The implementation in silicon came later. You had to understand and buy into the conceptual model and then the software to maximize your return from the Transputer. A steep learning curve was involved. In the end, the Transputer was overtaken by simpler, better-funded, mainstream approaches. This book gives an overview of the Transputer history and architecture. Two real-world project case studys and over 300 references are included.

The x86 describes not only a line of microprocessor chips dating back to 1978, but also an instruction set architecture (ISA) that the chips implement. The chip families were built by Intel and other manufacturers, and execute the same instructions, but in different manners. The results are the same, arithmetically and logically, but may differ in their timing. Why the focus on the Intel x86? It was the basis of the IBM personal computer (PC) family and its spin-offs. It has transitioned from a 16 to a 32 to a 64-bit architecture, keeping compatibility for more than 30 years. It's an de-facto industry standard that has withstood the test of time. This book covers the Intel ISA-16 and ISA-32 architectures from the 8086/8088 to the Pentium, including the math coprocessors. A chart of ISA processors is included. The purpose of this book is to provide the basic background information for an understanding of the 80x86 family, the IBM Personal Computer (pc), and programming in assembly language as an introduction to the broader field of Computer Architecture. It will stress the pervasiveness of this pc-based technology in everyday things and events. It will provide an introduction to Software System Engineering and the Design for Debugging methodology. This book is a spin-off of a course in Computer Architecture/System Integration, taught in the graduate Engineering Science Program at Loyola College (now, Loyola University in Maryland). If we learn to program in the language c, for example, we can take our skills to any computer with a set of c-based tools. If we learn IA-32 assembly language, we have to relearn a language if we switch to a different architecture. So, why do we learn assembly language? Because it gives us insight into the underlying hardware, how it is organized, and how it operates. This book is dedicated to the graduate students in Engineering Science at Loyola College, Columbia Campus, who took the course EG-611, "System Integration I, the x86 Architecture and Assembly Language." The course was given to hundreds of students over a span of 15 years by myself and others. An Extensive bibliography is provided.

This book discusses.the use of microprocessors in space missions, from the earliest 4-bit machines to the most current 64-bit implementations. It covers the transition from monolithic processors with extensive glue logic, to IP cores instantiated in FPGA's. It gives the high-lights of the microprocessors sent and being sent into space, and the problems of sustaining their operations there. Microprocessors orbit the earth, sit on other planets, and have left the Solar system into interstellar space. They are the key components for spacecraft autonomy, and for collecting, storing, and returning the volumes of information that we receive from off-planet sources. Spacecraft microprocessors are a special subset of embedded computers. Most spacecraft include 10's ro 100's of processors, doing tasks such as attitude and orbit control, power monitoring and control, telemetry formatting and command handling, data storage management, and instrument control. Without these microprocessors, the amount that we know about our neighboring planets and the intervening space would be vastly limited. Early flight computers were custom designs, but cost and performance issues have driven the development of variants of commercial chips. Aerospace applications are usually classic embedded applications. Space applications are rather limited in number, and, until recently, almost exclusively meant NASA, ESA, or some other government agency. Flight systems electronics usually require MIL-STD-883b, Class-S, radiation-hard (total dose), SEU-tolerant parts. Specific issues of radiation tolerance are disucssed. Class-S parts are specifically for space-flight use. Because of the need for qualifying the parts for space, the state-of-the-art in spaceborne electronics usually lags that of the terrestrial commercial parts by 5 years. The new Cubesat concept bring the idea of a personal satellite within the reach of University Programs, and even for some individuals.Processors used in aerospace applications, as any semiconductor-based electronics, need to meet stringent selection, screening, packaging and testing requirements, and characterizations because of the unique environment. Most aerospace electronics, and the whole understanding of radiation effects, were driven by the cold war defense buildup from the 1960's through the 1980's. This era was characterized by the function-at-any-cost, melt-before-fail design philosophy. In the 1990, the byword was COTS -- use of Commercial, Off-The-Shelf products. Thus, instead of custom, proprietary processor architecture's, we are now seeing the production of specialized products derived from commercial lines. In the era of decreasing markets, the cost of entry, and of maintaining presence in this tiny market niche, are prohibitively high for many companies.
