Fundam.ntals of digital Logic and m.crocom.uter design , has long been hailed for its clear and sim.le presentation of the principles and basic tools required to design typical digital system. such as m.crocom.uters. In this Fifth Edition, the author focuses on com.uter design at three levels: the device level, the logic level, and the system.level. Basic topics are covered, such as num.er system. and Boolean algebra, com.inational and sequential logic design, as well as m.re advanced subjects such as assem.ly language program.ing and m.croprocessor-based system.design. Num.rous exam.les are provided throughout the text. Coverage includes: digital circuits at the gate and flip-flop levels Analysis and design of com.inational and sequential circuits m.crocom.uter organization, architecture, and program.ing concepts design of com.uter instruction sets, CPU, m.m.ry, and I/O System.design features associated with popular m.croprocessors from.Intel and m.torola Future plans in m.croprocessor developm.nt An instructor's m.nual, available upon request Additionally, the accom.anying Cd-ROm. contains step-by-step procedures for installing and using Altera Quartus II software, m.Sm.6.11 (8086), and 68asm.im.(68000), provides valuable sim.lation results via screen shots. Fundam.ntals of digital Logic and m.crocom.uter design is an essential reference that will provide you with the fundam.ntal tools you need to design typical digital system..
