The authors take a 'No Mysteries' approach to computer systems. They interrelate three different viewpoints to provide a unique understanding of the subject: the perspective of the logic designer, the assembly language programmer, and the computer architect. The book has up-to-the-minute coverage of the latest developments in microprocessors, including ALU, pipelining, memory hierarchy, networks and the Internet. And, rather than focusing on a single type of architecture, Heuring and Jordan examine both CISC and RISC models at the ISA level using the unambiguous language of RTN (Register Transfer Notation), allowing for a more in-depth appreciation of different machine structures and functions. The authors examine general purpose machine, machine languages, and digital logic, some real machines, processor design, processor design - advanced topics, computer arithmetic and the arithmetic unit, memory system design, input and output, peripheral devices, communications, networking and the Internet. For computer science and engineering professionals.
