NAMC-ODSP-M: DSP based Media Processing/Gateway

Audio and video detection,transcoding and acceleration for VoIP and SS7 solutions in AMC formfactor (MicoTCA and AdvancedTCA)

The NAMC-ODSP-M is a DSP based media processing/gateway AMC (AdvancedMC) that enables you to add video and audio acceleration to your AdvancedTCA® (ATCA®) and MicroTCA® (µTCA, MTCA) systems. It provides a broad range of audio/video codecs and algorithms in a compact AMC module, including H.264, MPEG4, H.263, G.711, G.729, SILK and Opus, DTMF, VoP, ISDN, SS7, ATM, VoIP, 3G protocols , I-TDM and TDM.

We have enhanced this standard functionality with additional video and voice quality features. An on-board FPGA simplifies management while enabling you to extend and customize the module to suit the exact needs of your application.

Integrated media gateway software provides rich audio and video applications with many codecs and protocols included and a simple configuration API so no DSP programming is required.

The NAMC-ODSP-M combines a powerful FPGA with an array of DSPs, an on-board switch and advanced media gateway software in a single-width, mid-size AMC module package to make it easier for you to add video and audio acceleration to your communications and networking systems.

Subsystem Processor
The on-board Xilinx Kintex-7 FPGA provides a local Linux processor for low-overhead management to the interfacing host system, while also giving you headroom for further extension and customization.

Media Processing Array
Up to eight Octasic OCT2224M DSPs, each with twenty-four DSP cores, provide the specialized processing power needed for video and audio media processing. Each DSP is equipped with its own private external 512MB DDR3 memory. This pool of DSPs is controlled from a host application over Ethernet using one of the redundant 1/10GbE ports of the NAMC-ODSP-M.

Interfaces
The AMC Ethernet ports are connected to the onboard managed Ethernet switch, to which each individual DSP is also connected by two separate 1GbE links to support, for example, 1080p video conferencing functions.

An FPGA-based ITDM to TDM controller enables one or two 8k channel ITDM interfaces, resulting in up 16k ITDM channels.

The NAMC-ODSP-M provides two redundant 10GbE interfaces at ports 4-7 and 8-11, and two redundant 1GbE interfaces at ports 0 & 1 of the common options region of the AMC backplane connector.

API
We provide an integrated Ethernet-based API for simple connection and configuration, and to enable the attachment of media gateway software.

Media Gateway Software
The NAMC-ODSP-M comes with Octasic’s Vocallo media gateway software, providing rich audio and video applications based on IP and TDM, with many codecs and protocols included, such as high density H.264, MPEG4, H.263 video codec and G.711, G.729, SILK, Opus and EVS voice transcoding. Octasic has enhanced this standard functionality with video and voice quality features such as video scaling, mixing and keying as well as echo cancellation, conferencing and adaptive noise reduction.

This covers many advanced audio / video applications, conferencing systems, audio / video transcoding, video surveillance and T.38 fax relay applications. The software provides an Ethernet packet-based configuration API so no DSP programming is required. It offers a very flexible architecture so that you can easily prototype, develop and deploy.

Application Optimization
N.A.T. can adapt the NAMC-ODSP-M to suit your application-specific needs with for example, fewer DSPs or a larger FPGA. Please contact us to discuss your requirements.
