This book deals with computer performance by addressing basic
preconditions. Besides general considerations about performance, several
new approaches are presented. One of them targets memory structures by
introducing the possibility of overlapping non-interfering (virtual)
address spaces. This approach is based on a newly developed jump
transformation between different symbol spaces. Another approach deals
with efficiency and accuracy in scientific calculations. Finally the
concept of a Neural Relational Data Base Management System is introduced
and the performance potential of quantum computers assessed.
