  • Matrix architecture for DSL applications
    Publication number: 20040184451
    Abstract: A Digital Subscriber Line [DSL] or Very High Speed Digital Subscriber Line [VDSL] telecommunication device with a downstream path and an upstream path, each path comprising a plurality of processors interconnected with a plurality of memories. The processors and the memories are arranged as input/output border column and row of an interconnecting matrix architecture constituted by interconnection devices able to interconnect the processors of the column with the memories of the row. This arrangement allows mapping different architectures simply by changing the status of the interconnection devices. The matrix arrangement provides a very flexible simulation platform for different possible applications and, even when implemented on silicon, the ASIC has a maximum of flexibility and can be adapted to different standard.
