SUNNYVALE, Calif.--Advanced Micro Devices Inc. today said chip testers from Teradyne Inc. and physical interface (PHY) design cores from Dolphin Technology Inc. will be available to support AMD's next-generation I/O data bus, called HyperTransport.
AMD said Boston-based Teradyne will offer testers incorporating HyperTransport I/O links for chips that connect to the new data bus. The HyperTransport bus was launched by AMD earlier this year to support its upcoming 64-bit microprocessors (see Feb. 14 story).
Five-year-old Dolphin Technology in Milpitas, Calif., has been collaborating with AMD to develop new HyperTransport PHY interfaces for integrated circuits that attach to the bus. The high-speed interface circuits transmit and receive digital data along wire pairs using analog signals.
AMD's move to line up test equipment and chip-interface support is part of its efforts to build momentum behind the HyperTransport technology. The Sunnyvale MPU company is also forming a new consortium of companies to back the high-speed data bus as well so that it can compete with Intel in the 64-bit processor markets (see May 4 story).
"We have selected Teradyne's J973EP with the inSync differential test option as one of the testing systems for the HyperTransport bus," said Gabriele Sartori, director of technology evangelism at AMD.
Teradyne has worked closely with AMD "to ensure that innovative and cost effective test solutions were in place to support the engineering and production ramp of this technology," said Rod Stewart, product marketing manager at Teradyne. "The HyperTransport bus is designed to enable semiconductor devices to communicate with each other at an unprecedented 1.6 Gbps gigabits per second," he added.
To enable a range of chip suppliers to quickly offer ICs with HyperTransport I/O capability, AMD turned to Dolphin Technology. "At the high speeds within HyperTransport technology, minor electrical variations may create interoperability issues," noted Mo Tamjidi, president of Dolphin Technology. He said his company has worked closely with AMD to develop a physical interface (PHY) that is "designed to allow companies to ensure product compatibility."
The HyperTransport bus was initially developed for high-performance PC and server platforms, but AMD claims it is now also gaining momentum in networking and communications devices, embedded applications, and other non-PC devices. In total, 150 companies are cooperating to drive HyperTransport technologies, according to AMD.
