New Video Networking Chips Use High-Performance Memory Controller Cores From Denali

VIXS digital video networking system-on-chip (SOC) gets memory bandwidth from Denali's Databahn™ memory controller cores

Palo Alto, Calif.,---October 21, 2002 Denali Software, the leader in memory system design and verification, today announced that its Databahn™ memory controllers have been licensed and successfully implemented in two new chips from ViXS: XCode – a content-secured multi-stream real-time transcoding chip; and Matrix – an IEEE 802.11a compliant baseband processor optimized for Rate-Range-Resilience and video delivery over IP networks. ViXS, the leading developer of end-to-end solutions for digital video networking, developed the two chips as part of an IP-based video distribution system with applications that include QoS delivery of broadcast quality video to clients like PCs, TVs & PDAs. XCode has already begun production ramp, while Matrix is set for sample by Q4 2002.

"Our Databahn memory controller solution offers high performance coupled with complete configurability to handle a very wide range of application requirements," said Kevin Silver, Vice President of Marketing at Denali. "ViXS is a great customer; they have some very exciting product applications with unique and demanding memory system requirements. We are very pleased to be a part of two successful chips with them."

"Denali has established a deep domain expertise in memory system design and verification," said Hugh Chow, Co-Founder / Vice President of Engineering at ViXS. "Memory system performance is critical to our application. By working with Denali, we were able to configure their Databahn memory controller core to perform exactly as required by our system design. Denali's support was also a key for the swift time-to-market of our product."

The two ViXS chips incorporate a 64bit memory interface to DDR-SDRAM. The Databahn memory controller is configured for 166MHz operation (333MHz data transfers), provides ECC (Error Correction Code), and supports various memory device configurations of up to a total of 256MB. The DDR sequencer was tested and fully functional using state-of-the-art DDR parts of both 128Mb and 256Mb.

About Databahn
The Databahn solution enables customers to configure a memory controller to match the exact application for the ASIC in order to achieve 100% bus utilization. Customization is supported by an online infrastructure at Denali's eMemory.com site where a browser-based GUI enables fast efficient configuration of various performance and interface options. To ensure compatibility with all the latest high-speed DRAM memory technologies, the configuration process is tightly integrated with a database of more than 4000 memory components, including the latest DDRII-SDRAM, DDR-SDRAM, FCRAM, and RLDRAM devices. The configuration process creates a machine readable specification file that drives the generation of the RTL from a single Verilog code base, which can then be simulated online to validate performance. Once the performance targets are met, other deliverables are generated, including verification routines, synthesis scripts, static timing analysis scripts, and documentation. The Databahn IP is library independent and covers solutions from .18u to .11u technologies, and DRAM device frequencies from 100-250MHz (200-500MHz data rate).
