Bifrost

"A stream processing framework, created to ease the development of high-throughput processing CPU/GPU pipelines. It is specifically designed for digital signal processing (DSP) applications within radio astronomy. A portable C API is provided, along with C++ and Python wrappers.

The heart of bifrost is a flexible ring buffer implementation that allows different signal processing blocks to be connected to form a pipeline. Each block may be assigned to a CPU core, and the ring buffers are used to transport data to and from blocks. Processing blocks may be run on either the CPU or GPU, and the ring buffer will take care of memory copies between the CPU and GPU spaces.

The purpose of bifrost is to allow rapid development of streaming DSP pipelines; that is, it is designed for stream-like data. A simple example of a data stream is the time series voltage data from a radio telescope’s digitizer card. Unlike file-like data, stream-like data has no well defined start and stop points. One can of course take a series of files, each containing a chunk of a time stream, and treat them as a stream.
