Mitsubishi's Graphics Memory Products Power REAL 3D's R3D/PRO-1000 Graphics Engine; 3D-RAM and Cached DRAM add quality and speed to image generator's graphics capability.

NEW ORLEANS--(BUSINESS WIRE)--Aug. 6, 1996--The Electronic Device Group of Mitsubishi Electronics America, Inc., and REAL 3D(R), a Lockheed Martin Company, jointly announced today that REAL 3D uses two of Mitsubishi's specialty graphics memory products as part of its high-end R3D/PRO-1000 real-time 3-D graphics engine. 

With Mitsubishi's 3D-RAM functioning as the frame-buffer memory and its Cached DRAM as the texture memory, the R3D/PRO-1000 provides a professional-level, standalone, real-time 3D graphics engine. The R3D/PRO-1000 offers a combination of low-cost and high image quality for commercial training, engineering visualization, and location-based entertainment applications. 

Mitsubishi's 3D-RAM improves data transfer rates in the R3D/PRO-1000 by integrating key functions on-chip, including an arithmetic logic unit (ALU) to accelerate Z-buffering and alphablending. In this way, the 3D-RAM helps eliminate read-modify-write bottlenecks and enables high-speed graphics architectures to achieve blistering-fast 3D graphics performance. 

The Cached DRAM (CDRAM) incorporates high-speed, on-board SRAM cache enabling fast texel access. The chip provides a high internal bandwidth that allows large blocks of data to transfer from the DRAM to the SRAM segments of the chip rapidly -- in a single DRAM cycle. Unlike other high-bandwidth memories, the Cached DRAM maintains low latency even under the demanding requirements of tri-linear MIP mapping. 

According to Walt Steiner, REAL 3D's high-performance graphics systems architect, "We selected Mitsubishi's Cached DRAM for the R3D/PRO-1000 for a number of reasons. The cache fill rate is very high, the cost is reasonable, the DRAM and cache are independently addressed, and it's available in 4 Mbit and 16 Mbit densities. Having cache memory on-board meant we didn't have to spend gates putting cache on our ASIC."

Said John Lenyo, REAL 3D's sales and marketing director, "When we decided to develop a high-performance, low-cost graphics engine for real-time image generator markets, it was most important for us to establish a new price-performance standard in the industry. This requirement was pervasive throughout the design, including selecting the optimum frame-buffer and texture memory devices for our leading-edge graphics architecture." 

"We are delighted that REAL 3D chose the 3D-RAM and Cached DRAM graphics memory products for their high-performance, cost-sensitive commercial systems," said Alan Wessel, Mitsubishi's product marketing manager for application-specific memories. "Their choice of our products helps confirm our leadership position in the 3D graphics memory market." 

Mitsubishi is demonstrating its 3D-RAM and CDRAM performance in REAL 3D's R3D/PRO-1000 graphics engine at the SIGGRAPH 96 graphics trade show in New Orleans, during the week of August 5, 1996.
