Magnetic Core Memory Decoded is a detailed work describing the operation and development of a magnetic core memory system of the type originally implemented in the 1940's through to the 1960's. Core memory was a major stepping stone in the development of modern digital computer systems and is a fascinating technology which encompasses many engineering disciplines. A full explanation of the technology is provided from the basics of magnetic core flux responses through the design and implementation of circuits required to create a fully functional memory system. The system presented in this book is a non-trivial design and while it is relatively small in terms of its storage capacity it is still large enough to give the reader a full account of the technology and the amazing secrets of this technology. This book is a must for anyone interested in the history of computing or is simply interested in the development of engineering technology.
This book describes the various tradeoffs systems designers face when designing embedded memory. Readers designing multi-core systems and systems on chip will benefit from the discussion of different topics from memory architecture, array organization, circuit design techniques and design for test. The presentation enables a multi-disciplinary approach to chip design, which bridges the gap between the architecture level and circuit level, in order to address yield, reliability and power-related issues for embedded memory.
Drawing on current research in psychology, a new philosophical account of remembering as imagining the past. In this book, Kourken Michaelian builds on research in the psychology of memory to develop an innovative philosophical account of the nature of remembering and memory knowledge. Current philosophical approaches to memory rest on assumptions that are incompatible with the rich body of theory and data coming from psychology. Michaelian argues that abandoning those assumptions will result in a radically new philosophical understanding of memory. His novel, integrated account of episodic memory, memory knowledge, and their evolution makes a significant step in that direction. Michaelian situates episodic memory as a form of mental time travel and outlines a naturalistic framework for understanding it. Drawing on research in constructive memory, he develops an innovative simulation theory of memory; finding no intrinsic difference between remembering and imagining, he argues that to remember is to imagine the past. He investigates the reliability of simulational memory, focusing on the adaptivity of the constructive processes involved in remembering and the role of metacognitive monitoring; and he outlines an account of the evolution of episodic memory, distinguishing it from the forms of episodic-like memory demonstrated in animals. Memory research has become increasingly interdisciplinary. Michaelian's account, built systematically on the findings of empirical research, not only draws out the implications of these findings for philosophical theories of remembering but also offers psychologists a framework for making sense of provocative experimental results on mental time travel.
The technological marvel that facilitated the Apollo missions to the Moon was the on-board computer. In the 1960s most computers filled an entire room, but the spacecraft’s computer was required to be compact and low power. Although people today find it difficult to accept that it was possible to control a spacecraft using such a ‘primitive’ computer, it nevertheless had capabilities that are advanced even by today’s standards. This is the first book to fully describe the Apollo guidance computer’s architecture, instruction format and programs used by the astronauts. As a comprehensive account, it will span the disciplines of computer science, electrical and aerospace engineering. However, it will also be accessible to the ‘space enthusiast’. In short, the intention is for this to be the definitive account of the Apollo guidance computer. Frank O’Brien’s interest in the Apollo program began as a serious amateur historian. About 12 years ago, he began performing research and writing essays for the Apollo Lunar Surface Journal, and the Apollo Flight Journal. Much of this work centered on his primary interests, the Apollo Guidance Computer (AGC) and the Lunar Module. These Journals are generally considered the canonical online reference on the flights to the Moon. He was then asked to assist the curatorial staff in the creation of the Cradle of Aviation Museum, on Long Island, New York, where he helped prepare the Lunar Module simulator, a LM procedure trainer and an Apollo space suit for display. He regularly lectures on the Apollo computer and related topics to diverse groups, from NASA's computer engineering conferences, the IEEE/ACM, computer festivals and university student groups.
