Hardware

From Casper

Many CASPER instruments use reconfigurable open-source hardware built around Xilinx FPGAs.

A typical CASPER instrument will have one or two ADC boards connected to an IBOB or ROACH for signal acquisition and a small amount of pre-processing and will send data over a network link to a BEE2, other ROACHes or commodity CPUs and GPUs, which will perform the bulk of the signal processing.
