16 Bit And 32 Bit Microprocessors

M->CREATED

An integrated, practical introduction to 16-bit and 32-bit microprocessors using the Motorola 68000 family as examples for electronics engineering, computer science, and technology students.

In the last few years, a large number of books on microprocessors have appeared on the market. Most of them originated in the context of the 4-bit and the 8-bit microprocessors and their comparatively simple structure. However, the techno-logical development from 8-bit to 16-bit microprossors led to processor components with a substantially more complex structure and with an expanded functionality and also to an increase in the system architecture's complexity. This books takes this advancement into account. It examines 16-bit micro-processor systems and descrihes their structure, their behavior and their programming. The principles of computer or ganization are treated at the component level. This is done by means of a detailed examination of the characteristic functionali ty of microprocessors. Furthermore the interactions between hardware and software, that are typical of microprocessor technology, are introduced. Interfacing techniques are one of the focal points of these considerations. This puplication is organized as a textbook and is intended as a self-teaching course on 16-bit microprocessors for students of computer science and communications, design engineers and users in a wide variety of technical and scientific fields. Basic knowledge of boolean algebra is assumed. The choice of material is based on the 16-bit microprocessors that are currently available on the market; on the other hand, the presentation is not bound to anyone of these microprocessors.

The era of the 16-bit microprocessor began in 1978 with the introduction by Intel of the 8086 and 8088 processors. Embedded controller versions of some of the general purpose cpu's were also added to the families. The 16-bit microprocessors were a follow-on to the previous 8 bit chips. They offered not only greater integer word size, but more address range, and faster operation than their predecessors. Initially implemented in multiple chips, the march of technology finally allowed these 16-bit machines to be a single chips design. Floating point hardware was developed for the 16-bit integer cpu's, and would later be incorporated into the same chip as the later 32-bit processors. At the same time, single-chip versions of some of the popular 16-bit minicomputers evolved. These included the DEC PDP-11 and Data Genera NOVA series. The 16-bit machines finally brought processing power to the desktop to begin to threaten the reign of the mainframes. Just imagine. A computer on every desktop. What would we do with that?

For Design Engineers, Software Architects & Computer Designers, a Guide to Completing Software Systems Using Motorola's MC68000 Family of Microprocessors

Coverage first concentrates on real-mode assembly language programming compatible with all versions of the Intel microprocessor family, and compares and contrasts advanced family member with the foundational 8086/8088. This building block presentation is effective because the Intel family units are so similar that learning advanced versions is easy once the basics are understood.
