CIRCUIT ELEMENT - CROSS-POINT BETWEEN TWO BUS LINES

摘要

20104-8536ABSTRACTDisclosed is a cross-point intended for ATD multiplexingdigital information in the form of packets of fixed lengthsbetween two buses (A-B and C-D); it is constituted by: a firstshift register (RAB), a first buffer register (RTE), a RAM (MRAM),a second buffer register (RTS), a second shift register (RCD), andlogic circuits constituted by decision units for packet extraction(DE) and insertion (DI), associated with decision Tables (TEX andTIN), and a management unit of the RAM (GM). Packet extractionsand insertions are effected in an asynchronous manner relative toeach other.
