The Design of Microcomputer Systems.
Abstract:
The nature of integrated circuit technology dictates an upper limit on the number of gates that can be placed on a single chip and still permit production that is economically feasible. This upper limit is constantly being increased by improving technology. The first integrated circuits had a small number of individual gates on a chip. As technology progressed, medium-scale-integrated MSI chips were produced with complex functions such as multiplexers, counters and shift registers. Early in the 1970s the maximum number of gates had increased to the point where a complete system or subsystem, such as a microprocessor could be placed on a single chip. This technology is referred to as large-scale-integration LSI. Author
