WebJan 1, 1998 · We present an efficient approach for the partitioning of algorithms implementing long convolutions. The dependence graph (DG) of a convolution algorithm is locally sequential globally parallel (LSGP) partitioned into smaller, less complex convolution algorithms. The LSGP partitioned DG is mapped onto a signal flow graph … WebThe main motivation is to provide support for the parallelisatio of audio processing operations in OpenCL devices such as GPUs, CPUs and accellerators. The repository includes a complete implementation of fast partitioned convolution, based on the FFT code. This is demonstrated in a csound opcode with accompanying CSD code. WebAn algorithmic approach to partitioned convolution was introduced by Gardner in (Gardner 1995) with a set partitioning of exponentially increasing block sizes. While this method is much more efficient than direct convolution, it misses out on the benefits of reusing the FFTs taken for each block size.
