UpZide is developing a reference design utilizing multiple Xtensa LX processors to implement the VDSL2 (second generation Very high-speed Digital Subscriber Line) standard. Because the standard is evolving, it’s essential that the VDSL2 data-path component be designed with the flexibility required to adapt to all possible changes. By designing with highly configurable Xtensa processors rather than RTL, and by extending the instruction set to handle the data-intensive demands of the VDSL2 standard, UpZide will be able to make available for license a fast, efficient, and programmable solution for this rapidly growing market.
The VDSL2 standard provides broadband connections at speeds of up to 100 Mbps symmetrical, which is fast enough to deliver the “triple play” applications of voice, data and video to a wide audience. This technology is seen as key to delivering VoIP (voice over Internet protocol), VoD (video on demand) and HDTV (high-definition television) simultaneously over standard telephone lines.
