METODO E DISPOSITIVO DI MEMORIZZAZIONE DI SEGNALI NUMERICI ORGANIZZATI IN MODO TRIDIMENSIONALE E SOGGETTI A TRASFORMAZIONI ORTOGONALI |
摘要 |
Method of storing signals consisting of a succession of digital samples with three-dimensional structure which have already been bidimensionally transformed, and which are subjected to the transformation along the third dimension requiring the contemporaneous availability of samples of corresponding positions, belonging to Z successive bidimensional groups. <??>The method provides a three-dimensional memory structure of Z planes each having the capacity of a group of samples, and the use of only two addressing modes of said memory alternating every Z groups; the first mode provides succesive positions of the various planes to be addressed in sequence, the second mode provides corresponding positions of Z planes to be addressed with increments by Z on each plane. During each addressing, a reading operation occurs followed by a writing operation of a new sample in the just-read position. <??>A device is also described for the implementation of the method. |
