fast_upfirdn: CPU & GPU implementations of scipy.signal.upfirdn

Project description

Fast Upfirdn

The core low-level function implemented here is an equivalent of scipy.signal.upfirdn but with support for both CPU (via [NumPy]) and GPU (via [CuPy]).

The version of upfirdn here supports several signal extension modes. These have been contributed upstream to SciPy and are available there for SciPy 1.4+.
