Fujitsu Microelectronics America's New VOIP CODEC Supports Four Simultaneous Channels, Choice of Vocoders, Embeddable in ASIC

Built around ARC core with DSP extensions, aimed at voice client applications

San Jose, CA, March 13, 2002 — Fujitsu Microelectronics America, Inc. (FMA) today introduced a new, embeddable VOIP CODEC core, along with a test chip and evaluation system, designed for wireless and broadband voice client applications.

Unlike standard VOIP, Fujitsu’s embeddable VOIP core can be easily integrated with any method of physical transmission, including 802.11x wireless LANs, Bluetooth Access points, 802.16 Fixed Wireless Access, and Internet-based multimedia messaging in the emerging 3G and 4G cellular markets. The new CODEC also can be used in ad hoc networked mobile wireless broadband terminals, Ethernet networks, cable modems, residential gateways and IP phones.

The VOIP CODEC supports up to four independent and simultaneous speech vocoders. Each channel can independently run any of the implemented vocoders: G.711, G.726, G.728, G.729AB and G.729E. Each channel provides echo cancellation (G.168), DTMF generation/detection and jitter buffering. The CODEC also supports dial-tone generation and reverse ring-back generation. It also has built-in bus master DMA interface for accessing host controller and system memory. The shared system memory eliminates the need for dedicated memory. The CODEC Serial Port (SPORT) unit provides standard PCM highway for interfacing to external analog circuits. A variety of programmable algorithms are available, so system capabilities can be quickly enhanced or upgraded.

Fujitsu’s VOIP core is based on ARC with DSP extensions and hardware accelerators, providing a flexible, powerful “soft᾿ solution for future algorithm enhancements and upgrades. It can be targeted to any process technology, including Fujitsu’s 0.11-micron flagship process.

“This new VOIP CODEC core is a key part of our program to provide complete SoC ASIC platforms in wireless and broadband markets,᾿ said Keith Horn, FMA’s vice president of marketing. “Communication networks are in transition to an IP-centric approach. This flexible, embeddable technology supports this shift, supporting emerging applications such as 802.11x WLAN, fixed wireless and others.᾿

Test Chip and Evaluation Board
In addition to the VOIP CODEC test chip, Fujitsu has developed a complete evaluation system of an IP phone / Residential Gateway using Ethernet transmission. A host ARC controller on the board runs the application software, real time operating system, network stack and MGCP protocol.

Pricing and Availability
Fujitsu now has samples of the VOIP CODEC test chips, manufactured using the company’s 0.25-micron CMOS technology. The VOIP CODEC soft core is now available to be embedded in any customer ASIC design. Pricing for the development kit starts at $2,495 each; test chips are now available for $100 each.
