More About This Textbook
Overview
Embedded Microcomputer Systems: Real Time Interfacing provides an in-depth discussion of the design of real-time embedded systems using 9S12 microcontrollers. This book covers the hardware aspects of interfacing, advanced software topics (including interrupts), and a systems approach to typical embedded applications. This text stands out from other microcomputer systems books because of its balanced, in-depth treatment of both hardware and software issues important in real time embedded systems design. It features a wealth of detailed case studies that demonstrate basic concepts in the context of actual working examples of systems. It also features a unique simulation software package on the bound-in CD-ROM (called Test Execute and Simulate, or TExaS, for short) - that provides a self-contained software environment for designing, writing, implementing, and testing both the hardware and software components of embedded systems.
Editorial Reviews
From the Publisher
"A complete description of designing embedded systems. One of my students came back from their first job saying this course and the text was helping greatly.""This is a very well thought-out textbook that covers a remarkable range of practical topics in this subject area."

Presents general design methodologies, with examples, using the Motorola 6805, 6808, 6811, and 6812 microcomputers. Includes a detailed study of hardware and software components of embedded systems, programming techniques and style, the development of debugging strategies for embedded systems (from both assembly language and C language perspectives), and detailed case studies. The CD-ROM contains a simulator which allows students to visualize activity occurring internally in the chip and to connect external hardware devices, as well as PDF, Examples, Assembly, and Embed directories, and other features.
