DIGITAL DIFFERENTIAL ANALYZER
Abstract
Analyses of the fundamentally disparate processing requirements of essential aerospace subroutines demonstrated that radically new digital computer design techniques and more efficient computer mechanizations were required. Mechanizations were optimized for the basic types of computations, then integrated using modal design concepts to achieve a simplified system through new time-sharing techniques. Initial basic theoretical analyses formed the foundations for the integrative efforts. Numerical Stieltjes integration algorithms were derived and developed for input processing and internal computations. Fundamental digital Stieltjes algorithms attained new levels of accuracy in single and multi-increment computers. Invention of second difference computation and communication led to the first general (quotient) algorithm with multi-increment accuracy and a multi-transfer unit which, in cases, equals precision of conventional devices of twice the complexity. In meeting demanding aerospace requirements, serial-parallel arithmetic modal techniques were developed.
