GDA's HyperTransport Tunnel core, code named HyperTunnel, is designed for reuse and it's flexible backend interface makes it easy to be integrated into wide range of applications. The core provides highly scalable upstream and downstream bandwidths through programmable link widths and frequencies.

HyperTunnel core meets today's demand for the increased bandwidth and offers more bandwidth than any existing solutions. The upstream link could be run 24 times faster than a 32 bit, 33 MHz PCI bus. The core is designed to operate the upstream link at up to 800 MHz DDR, yielding an effective transfer rate of 1.6 Gbits per second per wire pair. The design targets networking, telecommunications, embedded systems and any application where high speed, low latency response, low pin counts and scalability are necessary.
