NAMC-ADSP

NAMC-ADSP

Advanced Mezzanine Card (AMC) CPU Board with either 8 or 16 Blackfin DSPs

The NAMC-ADSP is a multi-purpose (tele-)communication resource board in AMC (Advanced Mezzanine Card) form factor, being equipped with either 8 or 16 Blackfin DSPs from Analog Devices.

The NAMC-ADSP is targeted at applications in communication environments with extensive need for voice or data computation. The module is designed to process standard telecom algorithms like voice and data compression and decompression or DTMF detection and generation. The NAMC-ADSP is suitable for any voice/data application in any signalling or VoP solution such as in ISDN, SS7, ATM, VoIP or 3G environments are suitable.

The module is capable of handling individual timeslots transmitted via I-TDM protocol over backplane Gigabit-Ethernet. The design is optimized for handling in parallel as many timeslots (TDM data) as possible. The TDM data streams are supplied by a standard I-TDM backplane interface located on port 0 and port 1 (redundant configuration) or port 8 of the AMC connector.
