Introduction:
The ACS team members made many fundamental contributions to computer architecture, and in the process created the first true superscalar machine design (including issuance of multiple interlock-controlled out-of-order instructions per machine cycle). As a result, the ACS team pioneered architectural methods that have become fundamental to many of today's high-performance VLSI PC processors. To learn more about this remarkable project, see the extensive historical reconstruction compiled by Dr. Mark Smotherman of Clemson University.
