Xilinx Virtex-7 FPGA in AMC signal processing module

August 08, 2013 // By Graham Prophet
CommAgility has announced the AMC-V7-2C6678, a high performance Advanced Mezzanine Card (AMC) module based on the Xilinx Virtex-7 FPGA and two TI TMS320C6678 multicore DSPs.

The module also provides fast, flexible I/O including Serial RapidIO (SRIO), Gigabit Ethernet and PCI Express. It is suitable for a range of high performance DSP/FPGA processing applications including telecoms and image processing.

The AMC-V7-2C6678 includes a high density XC7VX415T-2 Virtex-7 FPGA as standard, with other FPGA options available on request. Virtex-7 FPGAs provide high DSP performance and I/O bandwidth, with total power consumption that is 50% less than the previous generation.

The new AMC also provides two TMS320C6678 fixed- and floating-point octal core DSPs from Texas Instruments (TI), based on TI’s KeyStone multicore architecture. The DSPs run at 1.25 GHz, giving a combined performance of 320 GFLOPS and 640 GMACS. With 16 DSP cores and shared memory, the new module delivers high DSP performance. Two fast 5Gbaud PCI Express links are provided to connect the FPGA with each of the two DSPs.

The AMC-V7-2C6678 provides flexible connectivity to the backplane and front panel, delivering high speed I/O to support the FPGA and two DSPs. The Gigabit Ethernet interface uses on-board switches for maximum flexibility and access to all DSPs on the card.

An IDT CPS-1848 Gen2 SRIO switch supports Serial RapidIO at up to 20 Gbps per port. As standard, the board includes a single front panel SFP+ optical interface that links directly to the FPGA, plus a single mini-SAS connector linked to the SRIO switch. Should applications require timing and synchronisation, this is achieved via the front panel or backplane clock I/O, enabling the module to sync easily to other equipment.

2GB of high bandwidth DDR3-1333 SDRAM is provided as standard for each DSP, with an additional 512MB x 16 of DDR3-800 SDRAM and 1GB x 32 of DDR3-1250 SDRAM provided for the FPGA. 256MB of flash memory is also included, which can be used to store multiple FPGA images and software. Separate glue logic is provided for board configuration and management. This allows control, FPGA configuration and
