ABSTRACT:
Disclosed is a memory-based switching matrix for cross-connecting the content of a plurality of input flows into the content of a plurality of output flows, the input flows being in the form of frames and said content being Time Division Multiplexed or packet data or whatever, the matrix comprising a number of physical memories for memorizing incoming input flows to be output in a predesigned order. The matrix is characterized in that the number of physical memories comprises a first number of memories having a writing role and a second number of memories having a reading role, with the second number being higher than the first number, and in that the role of each memory changes after at least one clock cycle. The arrangement according to the invention saves a number of physical memories with respect to known arrangements.
