A parallel algorithm for rotating-frame zeugmatography.
An algorithm, which utilizes a high degree of parallel processing, has been developed for two-dimensional rotating-frame zeugmatography so that a picture of 256 X 256 pixels can be generated with a minicomputer system 2 sec after data accumulation. An array processor is employed as a second processor and, the refresh memory of a display unit is used as a fast data storage entity. Approximately half the calculations are carried out in the array processor during the nuclear relaxation period. Data movement to and from the display memory occurs largely during, and in parallel with, the array processing. The sequence can be run at a repetition rate of 35 msec per free induction decay and the algorithm can be implemented in any two-dimensional experiment of the Fourier transform genre.
