FPGA Based Scaled Down Model for Heterogeneous Spectrometers in Radio Astronomy Applications
Radio astronomy is a non-commercial, passive user of the radio frequency spectrum. It is also the branch of fundamental scientific research that provides them with the most useful data on the origins of the people universe. This paper is about a heterogeneous design, allowing them to benefit from the strengths of FPGAs. A design called the Packetized Astronomy Signal Processor, or PASP, is run on the FPGA. PASP splits up the large band into smaller bands that can be processed using off the shelf servers. The sub bands are put into packets on the FPGA and sent over a gigabit Ethernet switch to a cluster of servers.
