ABSTRACT:
The device and method disclosed relate to the field of electronic devices and methods enabling the transposition of any even-order square matrix, the elements of which are given in sequence. The goal is to provide for the transposition of sequences of data representing elementary image blocks, without any duplication of the memory space needed to store an elementary block, in optimizing the two parameters of operating speed and space occupied on silicon. This goal is achieved by a buffer memory divided into two identical storage half-planes, working together with a device for the sequencing of the reading/writing operations, providing simultaneously for a reading operation on one of the storage half-planes and a writing operation on the other half-plane.
