Efficient channelization on a graphics processing unit

Bruce Merry

Cited by 0Open access

Abstract

We present an implementation of a channelizer (F-engine) running on a graphics processing unit (GPU). While not the first GPU implementation of a channelizer, we have put significant effort into optimizing the implementation. We are able to process 4 antennas each with 2 Gsample / s, 10-bit dual-polarized input and 8-bit output, on a single commodity GPU. This fully utilizes the available peripheral component interconnect express (PCIe) bandwidth of the GPU. The system is not as optimized for a single high-bandwidth antenna but handles 6.2 Gsample / s, limited by single-core central processing unit (CPU) performance.
