Degrees of parallelization for a typical BCI software application. Figure shows processing steps applied by a BCI application to a stream of neural data. (A) No parallelization, i.e. all processing steps are executed sequentially in one thread on a single CPU core. (B) Each processing step is executed in a separate thread. The computations of each thread can be handled by a different core. (C) Independent substream parallelization. Feature extraction and movement decoding steps are split into functionally independent computations, e.g. by computing the features for each channel in a different thread.
