Logic design and its effects on the HITAC M-880 basic scalar processor are described. The M-880 is a high end mainframe computer which uses current high speed circuits and packaging technologies, as well as logic methods, to improve performance. An optimal pipeline stage evaluation method is proposed, together with a new cache access method termed merge access. The combined effect of the logic methods is a 10% improvement in processor performance with online transaction processing.>
