Boards for Roach
The ROACH (Reconfigurable Open ArchitectureComputing Hardware) board family is a series of FPGA boards developed by UC Berkeley's CASPER (Collaboration for Astronomy Signal Processing and Electronics Research) group. https://casper.berkeley.edu/wiki/Hardware
These boards incorporate a large FPGA (Xilinx Virtex-5 in ROACH-1, or Virtex-6 in ROACH-2), memory, high-speed (10Gb/s) interconnect, and a standardized interface for data converters, allowing the development of highly compute-intensive instruments for radio astronomy and other scientific applications. CASPER maintains a large gateware library to permit streamlined implementation of complex designs using a high-level (Matlab Simulink) tool flow.
The ROACH-1 Board
The ROACH-2 Board
Over the last several years I've developed a number of data conversion boards and a frequency conversion board for the ROACH family. The hardware and gateware designs are all open-source: schematics are available here, and source code is available on the CASPER website. I build small quantities of some of these boards and offer them for sale, and sometimes have some in stock.
