Denaliís Databahn Memory Controller Delivers MPEG-2 to NTT HDTV CODEC

5/9/2003 - Denali Software, Inc., the leading provider of semiconductor intellectual property (SIP) and electronic design automation (EDA) tools for chip interface design and verification, announced that NTT Electronics Corp. (NEL) is now shipping an HDTV CODEC that incorporates the DatabahnTM memory controller core. The single chip solution, jointly developed by NTT Cyber Space Laboratories and NEL, delivers advanced image processing capabilities to HDTV video applications based on MPEG-2 standards.

The NEL VASA (Versatile and Advanced Signal Processing Architecture) chip, the worldís first single-chip MPEG-2 HDTV CODEC, integrates Denaliís Databahn memory controller core, which enables the chip to interface with external DDR-SDRAM memory running at clock rates up to 200MHz (400MHz data transfers).

"We are very pleased with Denaliís Databahn Memory controller cores," said Dr. Ryota Kasai, General Manager, 1st Product Group, Electronics Business Group of NEL. "Image processing applications require high-performance memory systems. Using the Databahn core, we were able to quickly configure the optimal memory controller for our application, and focus on our core competencies. With Denali's help, we were able to meet our performance targets and get our product to market in record time."

"NELís success with Databahn in its VASA chips is another demonstration of the flexibility and performance capabilities of our Databahn cores," said Kevin Silver, vice president of marketing at Denali. "A single NEL VASA chip performs the work for what used to require several dedicated chips for processing HDTV video data. We are proud that NEL has chosen Databahn for the memory system in this very complex system-on-chip design."

The NEL VASA (Versatile and Advanced Signal Processing Architecture) chip is the world's first single-chip MPEG-2 HDTV CODEC. The 60-million-transistor VASA chip delivers advanced image processing capabilities to HDTV applications based on the MPEG-2 standard. Because huge volumes of calculations are required for processing video data, in the past, several dedicated chips had been used for encoding (compression) and decoding (decompression) HDTV video. NEL's new single-chip solution not only paves the way for smaller, and lower cost HDTV systems, but by using several of these chips, it will open the door for applications in digital cinema, stereo 3D TV, multi-angle TV, and a wide range of other large-screen video applications of the future.
