MUSIC Semiconductors' New Harmony 1M and 2M Ternary CAMs Perform over 100 Million Packet Searches per Second.Business & Technology Editors NOTE TO MEDIA: Photo is available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com and at www.newstream.com MILPITAS, Calif.--(BUSINESS WIRE)--Aug. 15, 2001 MUSIC Semiconductors, Inc. addresses the needs of the market for faster packet header processing with the introduction of the MUAD16K136, the first member of the Harmony(TM) Ternary (programming) ternary - A description of an operator taking three arguments. The only common example is C's ?: operator which is used in the form "CONDITION ? EXP1 : EXP2" and returns EXP1 if CONDITION is true else EXP2.

CAM provides the most efficient address lookup and packet classification, as well as being the easiest type of device to program. CAM simultaneously compares the desired packet header information against an array of data, achieving a search time far less than with RAM-based algorithms. Harmony is designed to provide high-speed packet classification and lookup of Ethernet, IPv4 and IPv6 addresses as well as packet classification in switches, routers and firewalls. The versatility of the MUAD also allows the creation of multiple search tables with multiple word widths within the same device. Lee Goldberg For the weather forecaster, see . Lee Goldberg is a novelist and television writer whose TV writing and/or producing credits include Diagnosis Murder, A Nero Wolfe Mystery, Hunter, Spenser For Hire, She-Wolf of London, , Senior Technology Editor for Chip Center(TM) on-line magazine (www.chipcenter.com) said, "MUSIC is leveraging their long expertise in delivering high performance general purpose CAMs." He explained, "Their ternary CAMs eliminate search steps and provide the flexibility for complex search techniques as packets are more thoroughly examined for content. As data flows and pipelines become regulated to guarantee a minimum rate, deep packet analysis and classification will be critical to resolve QoS issues." Mr. Goldberg cited the product's inherent benefit as, "...MUSIC's Harmony devices will help designers address the needs of subscribers who are going one step further in anticipating future bandwidth requirements Bandwidth requirements (communications) The channel bandwidths needed to transmit various types of signals, using various processing schemes. Every signal observed in practice can be expressed as a sum (discrete or over a frequency continuum) of sinusoidal ." Harmony is functionally compatible with other ternary CAM devices from all major manufacturers, and is fully socket compatible with Lara Networks' LNI LNI Lecture Notes in Informatics LNI Local Network Interconnect LNI Lamprey Networks Incorporated LNI Lecture Notes of Informatics 7010 and LNI7020. However, the MUSIC chip is a faster, moderate power device. Harmony also boasts architectural features such as a double data rate I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output , search power management, and multi-match output. Harmony simplifies the handling of associated data with its glueless interface to industry standard synchronous SRAMs, giving designers a competitive edge by easily incorporating high performance ternary search capability into network equipment. The MUAD16K136 is a 16K by 136 bit device, with a capacity of 2.2 million ternary data elements. The MUAD8K136 is 8K by 136 bits wide and supports 1.1 million elements. Both are configurable as 8K/4K by 272 or 32K/16K by 68 bits. Harmony performs over 100 million searches per second on a 68- or 136-bit field, and over 50 million searches per second in a 272-bit configuration. It is packaged in a 272 BGA (Ball Grid Array) A popular surface mount chip package that uses a grid of solder balls as its connectors. Available in plastic and ceramic varieties, BGA is noted for its compact size, high lead count and low inductance, which allows lower voltages to be used. . Availability MUAD16K136 devices are currently sampling, available for $70.00 each in production quantities. Available tools include SWIFT simulation and IBIS models as well as a BSDL (Boundary Scan Description Language) An IEEE language used to describe structures for boundary scan testing. See scan technology. file. Verilog code for an FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. is available to interface Harmony to a variety of network processors on the market.
