Flexible virtual design for voice processes
SANTA BARBARA, CA, May 16, 2006 – D2 Technologies announces today that its vPort™ VoIP software has been implemented on the ARM926e RISC processor embedded within the Texas Instruments OMAP 1710 and OMAP 850 SoC (system on a chip). This allows fully-featured VoIP applications to be offered with or without the need for DSP hardware, resulting in a flexible virtual DSP design that can address a wide variety of applications.
D2’s integrated software solution, called vPort, includes audio drivers, voice processing functions (like compression, echo cancellation, Caller ID, DTMF, packet loss concealment, etc), RTP packetization, Jitter Buffer, SIP signaling and application layer. For dual mode wireless applications on the OMAP850, where the DSP is committed to other baseband signal processing functions, vPORT can execute entirely on the ARM CPU. In other applications where the ARM processor is needed for high level functions, the voice signal processing subsystem of vPORT can be executed on the attached DSP on the OMAP1710. Introduced three years ago, D2’s vPort software is deployed in residential end-point products, and is designed for CPE end-point products such as wired/wireless Voice-enabled Terminal Adapters, routers and gateways, as well VoIP phones and handsets.
ARM Processors Make Efficient Use of Silicon
“ARM processors make efficient use of silicon and memory, which allows semiconductor companies to make economical semiconductor devices with the low power consumption required of wireless or portable devices. This, coupled with efficient signal processing instructions useful for voice algorithms make the ARM an ideal platform for running D2’s VoIP software,” according to D2 President, David Wong.
The Texas Instruments OMAP 1710 is an effective platform for use in handsets for single-mode WiFi applications or dual-mode WiFi/cellular applications. Its unique multi-engine design provides software/hardware accelerators for improved multimedia and graphics performance. Plus the 1710 has integrated hardware and software security features and ultra-low standby power consumption.
D2 is a Member of the ARM Connected Community
D2 has also joined the ARM Connected Community, which is a global network of companies aligned to provide a complete solution for products based on the ARM architecture. ARM offers a variety of resources to Community members, including promotional programs and peer-networking opportunities that enable a variety of ARM Partners to come together to provide end-to-end customer solutions.
