Alternative to scipy.lfilter

Installing cusignal on windows 10

QUESTION

Alternative to scipy.lfilter

Asked 2020-Oct-29 at 05:30

is there a way to have an alternative implementation of lfilter within scipy? I want to use the cusignal library and lfilter is not supported at the moment.

Here's my my current code that I want to speed up:

...

Even though your filter is in principle an infinite impulse response (IIR) filter, the impulse response for this particular filter decays very fast. You can compute the impulse response by running an impulse through it with lfilter like lfilter(b, a, [1] + [0]*99). Here is what I get:

As you can see, the taps are nearly zero above sample 20 or so. So you can take the first 20 samples of the impulse response to make an accurate truncated FIR approximation. From there, you can apply that FIR approximation with any FIR filtering function, like np.convolve, scipy.signal.convolve, or scipy.signal.fftconvolve.

Another thought: With any of these filtering functions, you could try casting all the args to np.float32. They might internally switch to a 32-bit float implementation that is faster than the 64-bit float implementation.

Install cusignal

A polyphase resampler changes the sample rate of an incoming signal while using polyphase filter banks to preserve the overall shape of the original signal. The following example shows how cuSignal serves as a drop-in replacement for SciPy Signal's polyphase resampler and how cuSignal interacts with data generated on GPU with CuPy, a drop-in replacement for the numerical computing library NumPy. This code executes on 2x Xeon E5-2600 in 2.36 sec. This code executes on an NVIDIA V100 in 13.8 ms, a 170x increase over SciPy Signal. Next, we'll show that cuSignal can be used to access data that isn't explicitly generated on GPU. In this case, we use cusignal.get_shared_mem to allocate a buffer of memory that's been addressed by both the GPU and CPU. This process allows cuSignal to process data online. This code executes on an NVIDIA V100 in 174 ms. Finally, the example below shows that cuSignal can access data that's been generated elsewhere and moved to the GPU via cp.asarray. While this approach is fine for prototyping and algorithm development, it should be avoided for online signal processing. This code executes on an NVIDIA V100 in 637 ms.
cuSignal has been tested on and supports all modern GPUs - from Maxwell to Ampere. While Anaconda is the preferred installation mechanism for cuSignal, developers and Jetson users should follow the source build instructions below; there isn't presently a conda aarch64 package for cuSignal.

Support

The complete cuSignal API documentation including a complete list of functionality and examples can be found for both the Stable and Nightly (Experimental) releases. cuSignal has about 75% coverage of the SciPy Signal API and includes added functionality, particularly for phased array systems and speech analysis. Please search the documentation for your function of interest and file an issue if you see a gap. cuSignal (Stable) | cuSignal (Nightly).
