ATCA and MicroTCA DSP module hosts TI 8-core chips

October 03, 2013 // By Graham Prophet
CommAgility's AMC-2C6678L is a high performance processing board in the mid-size Advanced Mezzanine Card (AMC) format, employing the multicore TMS320C6678 DSP performance for voice, video, image processing, telecoms and stepper control applications.

With 16 DSP cores and shared memory, the new module is suitable as a DSP accelerator or front end processor in AdvancedTCA systems, where it can provide the horsepower required for a range of high performance applications including image sensor processing, voice/video, telecoms and stepper control. The AMC-2C6678L is also suited to use in MicroTCA chassis, or standalone with suitable power and cooling.

The module includes two Texas Instruments TMS320C6678 fixed- and floating-point octal core DSPs, which run at 1.25 GHz core speed, giving a combined performance of 320 GFLOPS and 640 GMACS. I/O includes Serial RapidIO (SRIO) to the backplane for high bandwidth data transfers. PCI Express and Gigabit Ethernet interfaces use on-board switches for maximum flexibility and access to all DSPs on the card, while the SRIO link is directly connected to one DSP and shared using Hyperlink. 4 GB of high bandwidth DDR3-1600 SDRAM is provided as standard, with 2 GB for each DSP. A separate 128 MB of flash memory is also included, which can be used to store DSP boot code.

Available software includes full board support libraries for the DSPs, and an IP stack with Telnet/TFTP for Ethernet-based board control and upgrade. 3L Diamond is available for additional control and management of multiple tasks across all 16 DSP cores. Additional debug support is provided via on-board serial port connectors, plus RS-232 and JTAG debug via the CommAgility AMC-BB Debug Breakout Board. The new module is a mid-size, single width PICMG AMC.0 R2.0 AMC.
