IP Telephony News Wrap-up for Mar, 21 2002

1. Fujitsu Introduces Embeddable VoIP CODEC Core
Fujitsu Microelectronics America has introduced a new embeddable VoIP CODEC core along with a test chip and evaluation system. The technology can be integrated with any method of physical transmission including 802.11x, Bluetooth, 802.16, and Internet based multimedia messaging in the 3G and 4G cellular markets. The CODEC call also be used in ad hoc networked mobile wireless broadband terminals, Ethernet networks, cable modems, residential gateways, and IP phones.

Fujitsu’s CODEC supports up to 4 independent and simultaneous speech vocoders. Each channel can independently run any of the implemented vocoders including G.711, G.726, G.728, G.729AB and G.729E. Each channel provides echo cancellation, DTMF generation/detection and jitter buffering. The technology supports dial-tone generation and reverse ring-back generation. It has a 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 unit provides standard PCM highway for interfacing to external analog circuits. A variety of programmable algorithms are available, so system capabilities can be enhanced or upgraded.

The CODEC is based on ARC with DSP extensions and hardware accelerators, providing a soft solution for future algorithm changes.

Fujitsu has also introduced a complete evaluation system of an IP phone/residential gateway using Ethernet transmission. A host ARC controller on the board runs the application software, RTOS, network stack, and MGCP protocol.

The CODEC soft core is currently available. The development kit starts at $2,495. The test chips go for $100 each.
