Introduction to Special Section on Programmable Logic Arrays

IN AN earlier paper [1], aspects of LSI were discussed that provide strong motivation for using programmed logic arrays for implementation of computer functions. These factors include extended use of a single chip design, the necessity to design for function, effective fault analysis and testing, and minimal design errors and changes. The approach to LSI exemplified by PLA´s will continue to be useful in VLSI, since the factors cited for large-scale integration will be even more prominent in the very large-scale integration environment with its demand for more on-chip function.
