The use of the edsac for mathematical computation

  • M. V. Wilkes


In order that a problem may be solved on an automatic digital calculating machine it must be expressed as a sequence of orders each calling for an elementary arithmetical or transfer operation. The paper describes the way this is done in the case of the EDSAC, a machine which has been built in the University Mathematical Laboratory at Cambridge. Special attention is paid to the use of conditional orders and to the handling of ’subroutines’, that is sequences of orders designed to perform some component part of a calculation such as the evaluation ot a square root.
