Xilinx Virtex-7 FPGA in AMC signal processing module
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 flash reprogramming over the SRIO or SPI interfaces.
Available software includes a full MicroBlaze board support library for the FPGA, and full board support libraries for the DSPs. 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 compact full-size, single width PICMG AMC.0 R2.0 AMC, and is suitable for use in both ATCA carriers and MicroTCA chassis. It can also operate standalone, with suitable power and cooling. A range of build options is available, and further customisation is possible in volume, to enable the best technical and commercial fit to a customer application to be achieved.
