GDA Technologies and Xilinx announced a HyperTransport compatibility test platform that they co-developed to support the HyperTransport Consortium's Compatibility Program.

The GDA HT8000 HyperTransport test platform consists of a 12.3 by 6.5-inch board which includes a Xilinx Virtex-II FPGA and two 16-bit HyperTransport interfaces for testing of host, tunnel, switch, or cave based HyperTransport configurations. The platform also provides a 16-bit SPI-4.2 and Gigabit Ethernet interface, enabling it to validate cores that bridge HyperTransport, SPI-4.2 and Gigabit Ethernet technologies. The board is controlled by a Motorola MPC8245 PowerQUICC II processor supported by 8MB Flash Memory, 128 MB SDRAM, and a serial port, and is supported by a GDA-provided Embedded Linux Operating System Port kit.

HyperTransport is described as a “universal chip-to-chip interconnect technology replaces and improves upon existing multilevel buses used in systems such as personal computers, servers and embedded systems while maintaining software compatibility with PCI I/O technologies.” The technology is said to provide up to 12.8 GB/second aggregate bandwidth using “easy to manufacture dual, unidirectional point-to-point links,” based on 1.2V low-power LVDS signaling and dual-data rate data transfers, with a packet-based data protocol.
