Debut of NEC's 3D Graphics Technology a Success at SIGGRAPH

(August 29, 2001)
The fastest graphics accelerator technology ever made by NEC was the showcase of the company's technology demonstration at SIGGRAPH 2001 in Los Angeles. The technology preview demonstrations, which showed NEC's line of graphics accelerator boards working on high-end, 32-bit systems using CAD, digital content creation, and broadcast postproduction applications, were a precursor to anticipated shipment of NEC's TE 5 graphics accelerator line in the fourth quarter of 2001.

A highlight among the technology demonstrations was NEC's TE 5 HD (High Definition) board, which, when available, will be aimed at the post-production market in preparation for HDTV broadcast. The TE 5 HD and a companion board demonstrated the functionality necessary to synchronize and edit various data streams and create a single output set. The task was performed with one workstation rather than a variety of independent hardware units.

The NEC TE graphics accelerator series utilizes a unique architecture that implements onboard local memory to store OpenGL display lists and instructions. This technique avoids bus bottlenecks within the workstation and makes display processing independent of other I/O traffic.

Recent Viewperf CDRS-03 tests indicate a projected performance of 65+, which exceeds the closest competitive products. Conservative preliminary estimates of other Viewperf 6.1.2 benchmark scores will be published after I/O driver tuning has been accomplished.

NEC TE 5 technology highlights:

  • Two custom-designed ASICs with 0.18u technology.

  • GRAPE LSI geometry engine - a highly-tuned 33Mvertex geometry engine with local memory for accelerating vertex data access.

  • PEAR LSI rendering engine - four pixel pipelines and a wide DDR SDRAM interface for unified video memory.

  • Up to 512MB local memory.

  • Up to 256 MB unified video memory for texture and frame buffer.

  • Full-scene anti-aliasing.

    The TE 5B and HD are expected to be announced in the US and Europe this fall and to appear in workstations from industry-leading vendors early next year.
