Microprocessors/microcomputers: Architecture, Software, and SystemsA new edition of the only book on the market that may be taught using either a general or a chip-specific approach. Updated to include 16-bit micros, magnetic disk memories, advanced direct memory access capabilities, and also a new chapter on interval timers and counters, including programmable timer-counter chips. The three sections of the book cover the hardware aspects of the microprocessor chip and its support chips, the systems hardware involving interfacing memory and input-output chips with the microprocessor, and the software. Topics covered include data flow in the microcomputer, macro- and micro-instructions, I/O transfers, flowcharting, assemblers, operating systems, and much more. The Z80, 8080A, and 8085 families are covered. |
