NAMC-ODSP-M Media Processing Acceleration for ATCA and MTCA

NAT's NAMC-ODSP-M modules add video and audio acceleration to AdvancedTCA and MicroTCA systems. It provides a broad range of audio/video codecs and algorithms, including H.264, MPEG4, H.263, and G.711, G.729, SILK and Opus, in a compact AMC module. An onboard FPGA simplifies management while extend and customize the module to suit the exact needs of the customers 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.
