Denali's Memory Processor Technology Chosen By Clearwater Networks; Memory Processor Enables Clearwater to Achieve Optimal Performance From Their 10-Gbit/s Network Services Processor.Business Editors & High-Tech Writers PALO ALTO Palo Alto, city, California Palo Alto (păl`ō ăl`tō), city (1990 pop. 55,900), Santa Clara co., W Calif.; inc. 1894. Although primarily residential, Palo Alto has aerospace, electronics, and advanced research industries. , Calif.--(BUSINESS WIRE)--June 18, 2001 Denali Software Denali Software, Inc. is an American software company, based in Palo Alto, California. The company produces electronic design automation (EDA) software and intellectual property (IP) design cores for memory and other standard interfaces. Inc., a world leader in high-performance memory subsystem design and verification, today announced that Clearwater Networks Inc. has licensed the company's Databahn(TM) configurable memory processor technology. Clearwater is developing next generation network services processors that provide deep packet processing capabilities at up to 10 Gbps. Clearwater has successfully employed the Databahn memory processor in its latest design, the industry's fastest network services processor. Clearwater Networks' CNP (Certified Network Professional) A professional designation and accreditation given to individual IT networking professionals by the Network Professional Association (www.npa.org). 810SP(TM) Network Services Processor is designed to perform advanced networking services in next-generation networking equipment such as edge routers Also called an "access router," it is a router that sits at the periphery of a network. Contrast with "core router," which is a router that resides in the middle of the network. See router and WAN router. See also edge device. , network appliances and network attached storage servers. It enables multi-gigabit advanced layers 4-7 networking services such as content-aware load balancing The fine tuning of a computer system, network or disk subsystem in order to more evenly distribute the data and/or processing across available resources. For example, in clustering, load balancing might distribute the incoming transactions evenly to all servers, or it might redirect them and traffic shaping Using methods to keep traffic flowing smoothly in a network. Although the term is often used synonymously with "traffic engineering," traffic shaping deals with managing the network moment to moment, whereas traffic engineering refers to the overall strategies employed in a network. , IPv6 gateways, network address translation, and VPN (Virtual Private Network) A private network that is configured within a public network (a carrier's network or the Internet) in order to take advantage of the economies of scale and management facilities of large networks. services. In these applications, the memory subsystem is a critical factor in determining overall system performance. "For advanced networking applications, memory latency In computing, memory latency is the time between initiating a request for a byte or word in memory until it is retrieved. If the data is not in the processor's cache, it takes longer to obtain them, as the processor will have to communicate with the external memory cells. -- the time to access off-chip data -- is the critical processing bottleneck," said Narendra Sankar, senior architect at Clearwater Networks. "When we set out to design the highest performance network services processor, we knew we also had to have the fastest memory subsystem." Sankar added, "The performance of Databahn has been great. Through our partnership with Denali, we have been able to develop a sophisticated memory subsystem that provides up to 300 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. DDR-SDRAM DDR-SDRAM - Double Data Rate Random Access Memory (600 MHz data transfers) while supporting 16 open banks and memory striping Interleaving or multiplexing data to increase speed. See disk striping. striping - data striping along with ECC (1) (Error-Correcting Code) A type of memory that corrects errors on the fly. See ECC memory. (2) (Elliptic Curve Cryptography) A public key cryptography method that provides fast decryption and digital signature processing. . Databahn has enabled us to deliver the industry's highest performance memory subsystem." "Performance is key for us, and we are already looking at Databahn for our next-generation designs," said Bradley Howe, vice president of engineering at Clearwater Networks. "Our long-term relationship with Denali will enable us to extract the maximum performance out of next-generation memory architectures." "Clearwater Networks is designing the highest performance processor for advanced networking services," said Kevin Silver, vice president of marketing at Denali. "These applications have a voracious voracious said of appetite. See polyphagia. appetite for memory bandwidth Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of the commonly used with minimal latency, and we're honored by their commitment to Databahn for their high-speed memory solution. The success of their design confirms that configurable memory processors are a compelling solution for high-performance SoC designs." Among the options available to the Clearwater Networks design team was a Web-based interface to configure the memory processor for optimal performance with Clearwater's memory access profile and the chosen memory configuration. Once integrated into the Clearwater SoC design, the Databahn memory processor enables Clearwater network services processors to extract optimal performance from new and emerging technologies with only minimal reconfiguration of the Databahn intellectual property (IP). About Databahn Databahn is the industry's first configurable memory processor. With Databahn, designers can configure the performance of their memory subsystem based on the type of memory components used and the memory access characteristics of their system. Databahn's online configuration environment enables designers to explore design tradeoffs, analyze product performance, and evaluate memory architectures early in the design cycle. To ensure compatibility with all the latest DRAM memory technologies, Databahn's online configuration process is tightly integrated with a database of more than 3000 memory components at www.eMemory.com. Designers also use the Web-based interface to automatically generate and export the synthesizable IP and related verification IP for their particular design and verification environment. Denali partnered with key customers and semiconductor memory vendors to develop Databahn and as a result, it is a highly integrated, market-focused solution for high-performance memory subsystems.
