Roach System


(ROACH - Reconfigurable Open Architecture Computing Hardware)


A major and unique product offering from Digicom is its ROACH (Reconfigurable Open Architecture Computing Hardware) system that was developed with major universities and research labs throughout the world.

The ROACH system takes the baseband data from the most powerful radio telescopes, changes it from analog to digital, and applies sophisticated digital signal processing filtering techniques to derive information about our universe. These systems are customized for each application as some applications require downloading a tremendous amount of data quickly, while others want to selectively download the data. Intricate modules and box-build projects, such as the ROACH system, IADC (analog to digital conversion boards), and IBOB (interconnect break-out boards), are totally turnkey.

ROACH is a Virtex5-based upgrade to current CASPER hardware. It merges aspects from the iBOB and BEE2 platforms into a single board. The CX4/XAUI/10GbE interfaces of both are kept, while combining the Z-DOK daughter board interface of the iBoB with the high bandwitdth/capacity DRAM memory and standalone usage model of the BEE2. ROACH is a single-FPGA board, dispensing with the on-board inter-FPGA links in favor of 10GbE interfaces for all cross-FPGA communications.
